Bolesławiec ( pronounced [bɔlɛˈswavʲɛt͡s] , Silesian : Bolesławiec , German : Bunzlau ) is a historic city situated on the Bóbr River in the Lower Silesian Voivodeship , in south-western Poland . It is the administrative seat of Bolesławiec County , and of Gmina Bolesławiec (being an urban gmina in its own right). As of June 2021, it has a population of 38,280. Founded in the 13th century, the city is known for its long-standing pottery -making tradition and heritage Old Town.

169-672: The name Bolesławiec is a patronymic name derived from the Slavic name Bolesław, composed of two elements of the old Polish, currently unused term bole(j) meaning very and sław meaning fame. This name literally means "very famous" and was given to the city in honor of the founder Bolesław I the Tall , who founded the city around 1190, granting it numerous privileges. In his list of place names in Silesia, published in Wrocław in 1888, Heinrich Adamy mentions

338-526: A German; according to the historian Kazimierz Jasiński , she was probably a member of the comital house of Everstein , Homburg , or Pappenheim . They had seven children: In German and Polish historiography there exists a controversy about the relations between Silesia and the Holy Roman Empire in the early medieval period. According to some German historians the date of 1163, when Bolesław and his brothers were allowed to return to Silesia,

507-592: A Roman denarius with a spear blade was discovered in Bolesławiec, followed in 1941 by a denarius of Gordian III from the years 238-244. These coins may prove the existence of a trade route in the area as early as the first half of the 1st millennium. What draws attention, however, is the discovery of a settlement (pottery) of the Luboszycki culture in Bolesławiec. Slightly further north of the city, in Parkoszów ,

676-468: A cemetery of this culture was found with five graves equipped with pottery and fragments of corpses as well as melted glass and a fragment of a comb. It is thought that settlement during this period occupied a small area along the Beaver River. The Slavs arrived in Silesia in the 7th century, but no traces of their residence at that time have been found in the Bolesławiec area, nor have the remains of

845-441: A distinctive Bunzlauer style are ball-shaped jugs and screw-lidded jars, often decorated with applied cartouches filled with intricate floral design. At first the entire pot, including the decorations, was covered in the same brown slip. Later examples used a yellowish lead glaze for the applied decorations which then stood out against the darker surface of the vessel (Adler, 95). A famous example of Bunzlauer pottery from this period

1014-529: A field study published in 2021 by researchers at Stockholm University found that they are often transferred from water to air when waves reach land, are a significant source of air pollution , and eventually get into rain. The researchers concluded that pollution may impact large areas. In 2024, a worldwide study of 45,000 groundwater samples found that 31% of samples contained levels of PFAS that were harmful to human health; these samples were taken from areas not near any obvious source of contamination. Rain

1183-556: A further diminution of his authority when he was compelled to give Głogów to his youngest brother Konrad. After this defeat, Bolesław retired from the Polish political scene and concentrated his efforts on the rule over his duchy. His brother Konrad's death without issue in 1190 resulted in the return of Głogów to his domains. During the last years of his reign, Bolesław devoted himself to economic and business activity. Colonization, initially from poor German areas, substantially accelerated

1352-458: A guild in order to enforce their monopoly of pottery making. Early Bunzlauer pottery is exceedingly rare today. The majority of a potshop's production would have been intended for farm and kitchen use: kraut containers, cheese sieves, pickling and preserve jars, baking forms, food molds, storage vessels, and so forth. Most of these stock-in-trade storage or cooking items have either disappeared or go unrecognized and undated today. What has survived

1521-786: A histonc complex of a psychiatric hospital was built between the current Piast and Tysiąclecia Streets, where the Provincial Hospital for the Nervous and Mentally ill now operates. Many Bolesław citizens took part in the Franco-Prussian War and in the battles of the First World War. The latter were commemorated with monuments: In the Evangelical church and in the municipal forest in the present Jelenlogórska Street (both no longer extant). Despite these wars,

1690-483: A long duration. The final droplet size distribution is an exponential distribution . The number of droplets with diameter between d {\displaystyle d} and D + d D {\displaystyle D+dD} per unit volume of space is n ( d ) = n 0 e − d / ⟨ d ⟩ d D {\displaystyle n(d)=n_{0}e^{-d/\langle d\rangle }dD} . This

1859-627: A moving sermon in St Mary's Church. The sermon caused a large part of the townspeople to convert to the Protestant side. In time, the Dominican monastery was abolished and St Mary's Church was turned into a Lutheran church, a state of affairs that did not change until 1629, when the church was returned to Catholics. The church housed the first known library of Boleslawiec. It was a so-called chain library, consisting of around 150 volumes. From 1525

2028-535: A native of Boleslawiec, was Andreas Scultetus. The city suffered severely during the Thirty Years' War, when Swedish troops passed through Bolesławiec more than once, leaving ruins in their wake. In addition, in June 1623, the city was hit by a major plague epidemic that led to deaths Despite the great destruction, the city managed to recover from the losses it had suffered, as evidenced by the subsequent rebuilding of

2197-521: A non-existent entity, a product of pre-war German historiography. The poorly attested settlement in this area in the early medieval period was initially due to the existence of a so-called zonal boundary running through a strip of forest between the Lusatian Neisse and the Beaver. With the development of settlement - Silesian on the one hand, and Lusatian-Milczański on the other - in connection with

2366-468: A number of books and leaflets in Bolesławiec, but the newspapers brought them the greatest fame. In addition to the city newspaper Bunzlauer Stadtblatt, the printing house also published specialized newspapers - the most famous title was Der Photograph, which was published on a global scale. The Fernbachs were finally dispossessed of their property in 1942 by the Nazi authorities. In 1913, the "Metropol" cinema

2535-460: A particular air temperature. How much water vapor a parcel of air can contain before it becomes saturated (100% relative humidity) and forms into a cloud (a group of visible tiny water or ice particles suspended above the Earth's surface) depends on its temperature. Warmer air can contain more water vapor than cooler air before becoming saturated. Therefore, one way to saturate a parcel of air

2704-410: A physical barrier such as a mountain ( orographic lift ). Conductive cooling occurs when the air comes into contact with a colder surface, usually by being blown from one surface to another, for example from a liquid water surface to colder land. Radiational cooling occurs due to the emission of infrared radiation , either by the air or by the surface underneath. Evaporative cooling occurs when moisture

2873-543: A point are estimated by using the value of reflectivity data at individual grid points. A radar equation is then used, which is Z = A R b , {\displaystyle Z=AR^{b},} where Z represents the radar reflectivity, R represents the rainfall rate, and A and b are constants. Satellite-derived rainfall estimates use passive microwave instruments aboard polar orbiting as well as geostationary weather satellites to indirectly measure rainfall rates. If one wants an accumulated rainfall over

3042-406: A rare rainfall event occurring on average once every 10 years. The rainfall will be greater and the flooding will be worse than the worst storm expected in any single year. A 100-year storm describes an extremely rare rainfall event occurring on average once in a century. The rainfall will be extreme and flooding worse than a 10-year event. The probability of an event in any year is the inverse of

3211-407: A result of this warming, monthly rainfall is about 28% greater between 32 and 64 km (20 and 40 mi) downwind of cities, compared with upwind. Some cities induce a total precipitation increase of 51%. Increasing temperatures tend to increase evaporation which can lead to more precipitation. Precipitation generally increased over land north of 30°N from 1900 through 2005 but has declined over

3380-491: A retouched base and two large scale fragments of splinters). The location of the finds is closely related to the mountainous character of the Bóbr. The valley of this river, 500 to 3,500 m wide, was under water in the spring and during continuous rainfall . The groundwater level meant that it drained slowly. As a result, the valley was difficult to access for a long time. For their own safety, late Palaeolithic man therefore stayed in

3549-543: A revolt by Mieszko Tanglefoot in 1172. In a major disturbance in the Silesian ducal family, Mieszko supported Jarosław, the eldest son of Bolesław, who was resentful against his father because had been forced to become a priest due to the intrigues of his stepmother Christina, who wished for her sons to be the only heirs. The rebellion was a complete surprise to Bolesław, who was forced to escape to Erfurt , Germany. This time, Frederick Barbarossa decided to support Bolesław with

3718-486: A strong armed intervention to restore him to his Duchy. Eventually Mieszko III the Old was sent by the high duke to calm the fury of the emperor and keep him away from Polish affairs. Mieszko III gave Barbarossa 8000 pieces of silver and promised him the restoration of Bolesław, who finally returned home at the beginning of 1173. However, despite his reconciliation with his brother and son, he was forced to divide Silesia and create

3887-649: A teardrop. The biggest raindrops on Earth were recorded over Brazil and the Marshall Islands in 2004 — some of them were as large as 10 mm (0.39 in). The large size is explained by condensation on large smoke particles or by collisions between drops in small regions with particularly high content of liquid water. Raindrops associated with melting hail tend to be larger than other raindrops. Intensity and duration of rainfall are usually inversely related, i.e., high-intensity storms are likely to be of short duration and low-intensity storms can have

4056-425: A tendency to break up at larger sizes. Smaller drops are called cloud droplets, and their shape is spherical. As a raindrop increases in size, its shape becomes more oblate, with its largest cross-section facing the oncoming airflow. Large rain drops become increasingly flattened on the bottom, like hamburger buns; very large ones are shaped like parachutes . Contrary to popular belief, their shape does not resemble

4225-470: A time period, one has to add up all the accumulations from each grid box within the images during that time. Rainfall intensity is classified according to the rate of precipitation, which depends on the considered time. The following categories are used to classify rainfall intensity: Terms used for a heavy or violent rain include gully washer, trash-mover and toad-strangler. The intensity can also be expressed by rainfall erosivity R-factor or in terms of

4394-462: A tinsmith before being shipped off by wagon or on the back of peddlers to customers in Prussia, Bohemia, and Poland, even as far away as Russia. The simple blue-on-white spongeware and swirlware productions of the 1880s and 1890s with their clear feldspathic glazes were successful initially, but something still more colorful and forceful was needed if modern customers were to be attracted. This demand

4563-541: Is water droplets that have condensed from atmospheric water vapor and then fall under gravity . Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectric power plants , crop irrigation , and suitable conditions for many types of ecosystems . The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts . If enough moisture and upward motion

4732-472: Is a grassland biome located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes , with rainfall between 750 and 1,270 mm (30 and 50 in) a year. They are widespread on Africa, and are also found in India, the northern parts of South America, Malaysia , and Australia. The humid subtropical climate zone is where winter rainfall is associated with large storms that

4901-511: Is a time when air quality improves, freshwater quality improves, and vegetation grows significantly. Tropical cyclones , a source of very heavy rainfall, consist of large air masses several hundred miles across with low pressure at the centre and with winds blowing inward towards the centre in either a clockwise direction (southern hemisphere) or counterclockwise (northern hemisphere). Although cyclones can take an enormous toll in lives and personal property, they may be important factors in

5070-654: Is accompanied by plentiful precipitation year-round. The Mediterranean climate regime resembles the climate of the lands in the Mediterranean Basin , parts of western North America, parts of Western and South Australia , in southwestern South Africa and in parts of central Chile . The climate is characterized by hot, dry summers and cool, wet winters. A steppe is a dry grassland . Subarctic climates are cold with continuous permafrost and little precipitation. In 2022, levels of at least four perfluoroalkyl acids (PFAAs) in rain water worldwide greatly exceeded

5239-718: Is added to the air through evaporation, which forces the air temperature to cool to its wet-bulb temperature , or until it reaches saturation. The main ways water vapor is added to the air are wind convergence into areas of upward motion, precipitation or virga falling from above, daytime heating evaporating water from the surface of oceans, water bodies or wet land, transpiration from plants, cool or dry air moving over warmer water, and lifting air over mountains. Water vapor normally begins to condense on condensation nuclei such as dust, ice, and salt in order to form clouds. Elevated portions of weather fronts (which are three-dimensional in nature) force broad areas of upward motion within

5408-563: Is also causing changes in the precipitation pattern, including wetter conditions across eastern North America and drier conditions in the tropics. Antarctica is the driest continent. The globally averaged annual precipitation over land is 715 mm (28.1 in), but over the whole Earth, it is much higher at 990 mm (39 in). Climate classification systems such as the Köppen classification system use average annual rainfall to help differentiate between differing climate regimes. Rainfall

5577-413: Is archaeological evidence for pottery being turned in the region as early as the 7th century. Documentary evidence demonstrates potting activity in Bolesławiec itself by the 14th century . High-fired earthenware covered in brown and yellow lead glazes was being produced in Bolesławiec from the late 15th century. By 1473, five separate potteries were at work in the city, and in 1511 they came together to form

5746-626: Is because it was located on the borderline between the Luboszycka culture and the Legnic region of the Przeworsk culture . The aforementioned finds from the period of Roman influence (1st century BC - 6th century AD) are not impressive. Between 1932 and 1933, two Roman coins (one bronze) were discovered in Bolesławice, which were in private possession and are now considered lost. Much earlier (1820)

5915-520: Is because the end of a belt of the so-called Blatnica type was found, coming from the Blatnica-Mikulżice zone dated to 790-830. It is distinguished by wares created after the fall of the Avar caganate, referring to Western wares. The end of the belt found in Bolesławiec has Carolingian features. The spur found, on the other hand, is an imitation of early Carolingian wares. Thus, Bolesławiec is located on

6084-842: Is commonly referred to as the Marshall–Palmer law after the researchers who first characterized it. The parameters are somewhat temperature-dependent, and the slope also scales with the rate of rainfall ⟨ d ⟩ − 1 = 41 R − 0.21 {\displaystyle \langle d\rangle ^{-1}=41R^{-0.21}} (d in centimeters and R in millimeters per hour). Deviations can occur for small droplets and during different rainfall conditions. The distribution tends to fit averaged rainfall, while instantaneous size spectra often deviate and have been modeled as gamma distributions . The distribution has an upper limit due to droplet fragmentation. Raindrops impact at their terminal velocity , which

6253-685: Is considered to be the moment when Silesia separated from Poland and became part of the Holy Roman Empire . On the other hand, Polish historians claim that Władysław II the Exile 's sons, who were allowed to return by High Duke Bolesław IV the Curly, were simply typical Piast dukes who ruled in the divided Kingdom of Poland . (see more in Differing views of the Silesian Piasts ). Rain Rain

6422-410: Is derived from natural sources such as volcanoes, and wetlands (sulfate-reducing bacteria); and anthropogenic sources such as the combustion of fossil fuels , and mining where H 2 S is present. Nitric acid is produced by natural sources such as lightning, soil bacteria, and natural fires; while also produced anthropogenically by the combustion of fossil fuels and from power plants. In the past 20 years,

6591-487: Is equally distributed through the year. Some areas with pronounced rainy seasons will see a break in rainfall mid-season when the Intertropical Convergence Zone or monsoon trough move poleward of their location during the middle of the warm season. When the wet season occurs during the warm season, or summer , rain falls mainly during the late afternoon and early evening hours. The wet season

6760-498: Is greater for larger drops due to their larger mass-to-drag ratio. At sea level and without wind, 0.5 mm (0.020 in) drizzle impacts at 2 m/s (6.6 ft/s) or 7.2 km/h (4.5 mph), while large 5 mm (0.20 in) drops impact at around 9 m/s (30 ft/s) or 32 km/h (20 mph). Rain falling on loosely packed material such as newly fallen ash can produce dimples that can be fossilized, called raindrop impressions . The air density dependence of

6929-497: Is measured in units of length per unit time, typically in millimeters per hour, or in countries where imperial units are more common, inches per hour. The "length", or more accurately, "depth" being measured is the depth of rain water that would accumulate on a flat, horizontal and impermeable surface during a given amount of time, typically an hour. One millimeter of rainfall is the equivalent of one liter of water per square meter. The standard way of measuring rainfall or snowfall

7098-408: Is measured using rain gauges . Rainfall amounts can be estimated by weather radar . Air contains water vapor, and the amount of water in a given mass of dry air, known as the mixing ratio , is measured in grams of water per kilogram of dry air (g/kg). The amount of moisture in the air is also commonly reported as relative humidity ; which is the percentage of the total water vapor air can hold at

7267-420: Is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands . In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains. On

7436-424: Is referred to as banded structure. Rainbands in advance of warm occluded fronts and warm fronts are associated with weak upward motion, and tend to be wide and stratiform in nature. Rainbands spawned near and ahead of cold fronts can be squall lines which are able to produce tornadoes . Rainbands associated with cold fronts can be warped by mountain barriers perpendicular to the front's orientation due to

7605-456: Is the "fancy ware" intended for display on the table or in the parlor and used with care. In addition to their utilitarian items, the Bunzlauer potteries of Silesia turned out elegant tankards, pitchers and containers, all bathed in the brown slip "glaze" that characterized this early phase of the Bunzlauer style. The tankards and pitchers often received pewter mountings. The first examples of

7774-561: Is the expected amount of liquid precipitation accumulated over a specified time period over a specified area. A QPF will be specified when a measurable precipitation type reaching a minimum threshold is forecast for any hour during a QPF valid period. Precipitation forecasts tend to be bound by synoptic hours such as 0000, 0600, 1200 and 1800  GMT . Terrain is considered in QPFs by use of topography or based upon climatological precipitation patterns from observations with fine detail. Starting in

7943-463: Is the hexagonal travel bottle with applied pewter mounts, originally belonging to Pastor Merge and dating to 1640–45. A type of round-bodied jug with spiraling ribs called a "melon jug" attained popularity in the last quarter of the 17th century and continued to be produced on into the next century. Some examples gave up the application of slip in favor of colored lead glazes. After leaving the potshop, many of these melon jugs received pewter lids made by

8112-411: Is the presence of a thick layer of air aloft which is above the melting point of water, which melts the frozen precipitation well before it reaches the ground. If there is a shallow near-surface layer that is below freezing, freezing rain (rain which freezes on contact with surfaces in subfreezing environments) will result. Hail becomes an increasingly infrequent occurrence when the freezing level within

8281-440: Is the standard rain gauge, which can be found in 100-mm (4-in) plastic and 200-mm (8-in) metal varieties. The inner cylinder is filled by 25 mm (0.98 in) of rain, with overflow flowing into the outer cylinder. Plastic gauges have markings on the inner cylinder down to 0.25 mm (0.0098 in) resolution, while metal gauges require use of a stick designed with the appropriate 0.25 mm (0.0098 in) markings. After

8450-399: Is to cool it. The dew point is the temperature to which a parcel must be cooled in order to become saturated. There are four main mechanisms for cooling the air to its dew point: adiabatic cooling, conductive cooling, radiational cooling, and evaporative cooling. Adiabatic cooling occurs when air rises and expands. The air can rise due to convection , large-scale atmospheric motions, or

8619-605: Is unknown whether Bolesław, his brothers, or his father directly participated in the expedition. However, despite the military victory and the humiliating submission of High Duke Bolesław IV the Curly to Frederick Barbarossa, the emperor decided to maintain the rule of Bolesław IV and the junior dukes in Poland, and not to restore Władysław II to the throne. Two years later, on 30 May 1159, the disappointed former high duke died in his exile in Altenburg. Despite his dissatisfaction at

8788-589: The Great Basin and Mojave Deserts . The wet, or rainy, season is the time of year, covering one or more months, when most of the average annual rainfall in a region falls. The term green season is also sometimes used as a euphemism by tourist authorities. Areas with wet seasons are dispersed across portions of the tropics and subtropics . Savanna climates and areas with monsoon regimes have wet summers and dry winters. Tropical rainforests technically do not have dry or wet seasons, since their rainfall

8957-529: The Gross-Rosen concentration camp in the town. One, at the current Staroszkolna 18 street was established in May 1944 on the basis of the camp of Jewish prisoners subordinated to Organization Schmelt , which had already existed in 1942. For almost the entire period of its existence, 1,000-1,200 Jews were imprisoned there, mainly Polish and Hungarian. They worked in several local arms factories. The second camp, at

9126-473: The Jagiellonian dynasty . At the end of the 15th century, the expansion of St Mary's Church took place, which resulted in the demolition of St Dorothy's Church. Part of this church was incorporated into the expanding church. Remembrances of this reconstruction have survived to this day in the form of inscriptions, placed in the walls of the basilica. In 1524 Jacob Süssenbach came to Boleslawiec and delivered

9295-534: The Mittelbau-Dora concentration camp in Thuringia. 541 prisoners out of about 800 Jewish prisoners and 441 out of about 600 non-Jewish prisoners endured this march. A small number of patients from both camps were left there and waited to be liberated by Soviet soldiers. After fighting with German troops, the city was captured on February 12, 1945 by the 7th Guards Tank Corps of the 3rd Guards Tank Army and

9464-638: The Pomeranian culture . At the end of the 2nd century A.D., the place of the Celts was taken by the people of the Luboszycki culture (mid 2nd century - 4th - 5th century A.D.). Research into settlement in this area in the pre-Roman period and the Roman influence, with the exception of loose finds and pottery proving the existence of a settlement, has so far not confirmed the existence of a settlement here. This

9633-708: The corded ware culture . This is confirmed by a site of this culture discovered in Bolesławice (stone axe). The largest concentrations of settlements occurred in the Głogowska-Barycka Proglacial Valley, the Silesian Lowlands and the Raciborsk Basin , in places with the most fertile soils and somewhat depleted forests. Due to the considerable mobility of the tribes of this culture, it is thought that their farming methods were dominated by herding and some forms of pastoralism . Over time,

9802-404: The leeward side of mountains, desert climates can exist due to the dry air caused by downslope flow which causes heating and drying of the air mass . The movement of the monsoon trough , or Intertropical Convergence Zone , brings rainy seasons to savannah climes . The urban heat island effect leads to increased rainfall, both in amounts and intensity, downwind of cities. Global warming

9971-409: The tropics appears to be convective; however, it has been suggested that stratiform precipitation also occurs. Graupel and hail indicate convection. In mid-latitudes, convective precipitation is intermittent and often associated with baroclinic boundaries such as cold fronts , squall lines , and warm fronts. Orographic precipitation occurs on the windward side of mountains and is caused by

10140-455: The westerlies steer from west to east. Most summer rainfall occurs during thunderstorms and from occasional tropical cyclones. Humid subtropical climates lie on the east side continents, roughly between latitudes 20° and 40° degrees away from the equator. An oceanic (or maritime) climate is typically found along the west coasts at the middle latitudes of all the world's continents, bordering cool oceans, as well as southeastern Australia, and

10309-538: The 10th-11th centuries becomes somewhat clearer when one turns to written sources. In the light of these, the Bobrzan tribe spread to the west of the Trzebowians and Dziadoszan, in the middle Beaver basin. Their presence here is attested only by the so-called Praga document of 1086, which is admittedly suspect, but the data contained therein are generally accepted to correspond with the situation in 973. It states that

On August 18, 2018, a free train of the Lower Silesian Railways, the so-called Ceramic Express. The city has a very well-preserved medieval street grid surrounding the Baroque town hall. There are tenement houses along

10647-565: The 19th century Bergemann Chronicle, the Bolesławiec stronghold had to defend itself fiercely and victoriously against the invading Czech army in 1094. As a result of the 12th-century fragmentation of Poland into smaller duchies still ruled by the founding Piast dynasty , it formed part of the duchies of Silesia , Legnica and Jawor until 1392. However, we do not have the first certain and source-confirmed information about Bolesławiec until around 1194. According to this version, Bolesławiec would have been named after Prince Bolesław Wysoki, who

10816-668: The Bober region and a post-Maglemian population, probably from the Chojnice-Pienkowskie culture , arrived in the area at the end of the Boreal period. They were mainly involved in the exploitation of the forest and water environment ( hunting , fishing ). The end of Mesolithic settlement occurred at the end of the 2nd Neolithic period. The Bolesławiec area was also penetrated in the Neolithic Age, especially by tribes of

10985-570: The Bolesławiec Cultural Center expanded their activities, numerous renovations and renovations of many places in Bolesławiec were started, with the railway viaduct, the city Planty and the Market Square at the forefront. The gradual restoration of St. Mary's Church, which was elevated to the status of a minor basilica on October 7, 2012, is still ongoing. In 2016, the 1st Secondary School celebrated its seventieth anniversary. Since

11154-742: The Bolesławiec area date from the younger phase of the Late Palaeolithic , i.e. around 10 000 BC. In 1974, on the high terrace of the Bóbr River in Bobrowice near Szprotawa , flint tools from this period were found (a Lyngby type leaf with two fragments of splinters ). At the same time, in Golnice near Bolesławiec, also on the terrace of a tributary of the Bóbr River, similar wares were discovered (an asymmetrical thylakus with

11323-626: The Duchy of Jawor-Swidnica, came under Bohemian rule, as did the whole Duchy. In the 14th century, from the taxes imposed on the Jewish population, the citizens of Bolesławiec financed the construction of the city walls between the Upper Gate and the Nicholas Gate. On 18 June 1429, the city fell victim to a devastating Hussite raid, during which a large number of inhabitants were slaughtered and

It had been thought that PFAAs would eventually end up in the oceans, where they would be diluted over decades, but

11661-404: The Earth's atmosphere which form clouds decks such as altostratus or cirrostratus . Stratus is a stable cloud deck which tends to form when a cool, stable air mass is trapped underneath a warm air mass. It can also form due to the lifting of advection fog during breezy conditions. Coalescence occurs when water droplets fuse to create larger water droplets. Air resistance typically causes

11830-580: The German name Bunzlau were mentioned in 1896 by the Silesian writer Konstanty Damrot in a book on local names in Silesia. In his book, Damrot also mentions older names from Latin documents: 1377 - Boleslawcze, 1417 - Boleslawicz, 1446 - Boleslavice. The Geographical Dictionary of the Kingdom of Poland gives two names of the town: the Polish name Bolesławiec and the German Bunzlau. The current name

11999-678: The Internet, such as CoCoRAHS or GLOBE. If a network is not available in the area where one lives, the nearest local weather or met office will likely be interested in the measurement. One of the main uses of weather radar is to be able to assess the amount of precipitations fallen over large basins for hydrological purposes. For instance, river flood control , sewer management and dam construction are all areas where planners use rainfall accumulation data. Radar-derived rainfall estimates complement surface station data which can be used for calibration. To produce radar accumulations, rain rates over

12168-570: The Latinized name Boleslavia and Boleslawetz, Bolezlavitz . The name of the town in the Latinized form Boleslavicz is mentioned in a Latin document from 1312 issued in Głogów . In a medieval document written in Latin from October 31, 1310, the city is mentioned under the Latinized name Boleslauia. In 1475, in the Latin statutes Statuta Synodalia Episcoporum Wratislaviensium, the town was mentioned under

12337-527: The Latinized name Boleslauia. In 1613, the Silesian regionalist and historian Mikołaj Henel from Prudnik mentioned the town in his work on the geography of Silesia entitled Silesiographia giving its Latin name: Boleslavia. The German name Bunzlau, which has been present since the 13th century, is a Germanized form derived from the Polish name. In the work of the Swiss geographer Matthäus Merian entitled "Topographia Bohemiae, Moraviae et Silesiae" from 1650 mentions

12506-523: The Lusatian culture collapsed, was followed by the Lateen Age (in the vicinity of Wrocław dated to between the 4th century BC and the end of the 2nd century AD). The Bolesławiec area was outside the influence of the 'Celtic' cultural groups. Despite this, a bronze clasp with a free heel and shield was found in Bolesławiec. It represents a rare specimen of a Munssingen clasp with a chord wrapped around

12675-414: The Nicholas Gate (located near the place where the intersection of Kutuzowa, Kubika and Komuna Paryska Streets is now). The city also had small suburbs in the area of the present Asnyka and Komuny Paryskiej Streets, and in the place of the present Defenders of Hel Park there was an Evangelical cemetery (surviving until the second half of the 20th century). In the area of today's Castle Square one can still see

12844-889: The Northeast and Midwest, which in the past decade, have seen 31 and 16 percent more heavy downpours compared to the 1950s. Rhode Island is the state with the largest increase, 104%. McAllen, Texas is the city with the largest increase, 700%. Heavy downpour in the analysis are the days where total precipitation exceeded the top one percent of all rain and snow days during the years 1950–2014. The most successful attempts at influencing weather involve cloud seeding , which include techniques used to increase winter precipitation over mountains and suppress hail . Rainbands are cloud and precipitation areas which are significantly elongated. Rainbands can be stratiform or convective , and are generated by differences in temperature. When noted on weather radar imagery, this precipitation elongation

13013-567: The Russo-French battle for Bolesławiec took place, ending with the expulsion of the French from the city. After the end of the war, Bolesławiec, whose defensive walls were partially destroyed by the French army began to develop dynamically. On 1 October 1845 a railway station was opened in the town, and a year later a large railway viaduct, one of the longest in Europe, was opened Soon afterwards

13182-564: The Tall Bolesław I the Tall ( Polish : Bolesław I Wysoki ; 1127 – 7 or 8 December 1201) was Duke of Wroclaw from 1163 until his death in 1201. Boleslaw was the eldest son of Władysław II the Exile by his wife Agnes of Babenberg , daughter of Margrave Leopold III of Austria , and half-sister of King Conrad III of Germany . Bolesław spent his childhood in the court of his grandfather and namesake, Bolesław III Wrymouth , in Płock . It

13351-597: The Wedding Palace. Bolesławiec was the birthplace of the German poet of the Baroque period, Martin Opitz, whose small monument has recently been located in Komuny Paryskiej Street. Opitz was one of the prominent representatives of the so-called Silesian poetic school, which had an enormous influence on German literature in the first half of the 17th century. Another well-known poet from this school,

13520-620: The architect Wendel Rosskopf was active in Boleslawiec, who took part in work on the interior of St. Mary's Church (Basilica) and created the so-called Vow Palace, still to this day located in the town hall and until the 20th century serving as the town inn. The Renaissance sgraffito in the lower part of the Town Hall tower has been preserved to this day, around which a copy has been made. A magnificent Renaissance portal, funded by one of Boleslawiec's 16th-century mayors, Paul Hanewald, leads to

13689-602: The area in areas that protected him from the water element. In the Beaver basin, 45 sites dating to the Mesolithic era have been discovered, from Bolesławiec to Krosno Odrzańskie . All of them, as in the Palaeolithic, are situated at the edges of valleys, on higher terraces or dunes , mainly on the southern or south-western side. The finds discovered are encampments ranging in size from 2-3 acres to 1 ha (in this case it would have been several small functional sites at

13858-405: The atmosphere exceeds 3,400 m (11,000 ft) above ground level. Convective rain , or showery precipitation, occurs from convective clouds (e.g., cumulonimbus or cumulus congestus ). It falls as showers with rapidly changing intensity. Convective precipitation falls over a certain area for a relatively short time, as convective clouds have limited horizontal extent. Most precipitation in

14027-634: The axe-like fine. The Bolesławiec bowl is the westernmost find of a fairly compact zone of such products in Silesia. After Silesia entered the circle of influence of the Great Moravian state, the Great Moravian influence, which is evident in the neighbouring Třebovian or Dziadoszan areas, did not reach the Boleslav region. Similarly, the Bohemian influences evident in the first tribe did not reach here. The situation regarding settlement in Silesia in

14196-663: The bail. The second of the fibulae , an iron one with a free heel and a small decorated ball, belongs to the late version of the Duchcow clasp (named after a treasure in Duchcow). Both are early Late Late forms. It is presumed that these finds indicate the existence of an additional route of contact between the Celts and the North. In the area of Szprotawa and Stara Kopernia near Żagań, iron covalvic clasps have been discovered in graves of

14365-542: The banks of almost the entire course of the Bóbr River, the area is not one of the large settlement areas (except in the vicinity of Żagań and Nowogród Bobrzański ). A dozen or so sites discovered in the vicinity of Bolesławiec indicate, however, a rather intensive penetration of this part of the lands on the Bóbr River by communities of the Lusatian culture. These sites (cemeteries) are located, among others, in Bolesławiec, Bolesławice, Buczek Mały, Kruszyna-Godnów, Rakowice-Otok. The short Halstadt period (700-400 BC), in which

14534-698: The border of the Early Carolingian influence, covering the Elbe Slavs, and then a belt east of the Oder and Lusatian Neisse up to Bolesławiec, and then as far as the Ślęza region and in a south-western direction covering Bohemia. An extremely important find is an iron bowl of the so-called Silesian type. Recently, it has been increasingly regarded as the original form of non-ruble money, which was superseded in Moravia and Malopolska by its more perfect form -

14703-677: The city - a section of the pilgrimage route to the tomb of Saint James in Santiago de Compostela in Spain. The town of Bolesławiec and its satellite communes Nowogrodziec , Ołdrzychów, and Bolesławice have a long ceramic history. The pottery is also identified with the German name for the town: Bunzlau . Bunzlauer ware ( Ceramika bolesławiecka ) evolved from a folk tradition into a distinct ceramic category distinguishable by form, fabric, glaze, and decoration. The term "Bunzlauer ware" may also be used to describe stylistically-related pottery produced in

14872-524: The city developed intensively - new streets were built, a suburban railway and a city theater were opened. A very important place on the pre-war map of Bolesławiec was the printing house of the Royal Orphanage, managed from 1872 by a printer of Jewish origin from Bolesławiec, Louis Fernbach. The Fernbach family managed the printing house until 1942 and during that time made it a very important printing center throughout Germany. The Fernbachs published

15041-477: The city under the name Boleslau. In 1750, the Polish name Bolesławiec was mentioned in Polish by Frederick II among other Silesian cities in an official ordinance issued for the inhabitants of Silesia. The name of the city as Bolesław was mentioned by the Silesian writer Józef Lompa in the book "A short sketch of the jeography of Silesia for initial science" published in Głogówek in 1847. The Polish name Bolesławiec and

15210-558: The city. From 1975 to 1998, Bolesławiec was administratively located in Jelenia Góra Voivodeship . In the 1980s, a student underground group operated in Bolesławiec for some time, printing patriotic leaflets and proclamations, supported by the city's " Solidarity ". After the political transformation, the city began to develop even more dynamically - new churches were built, the Youth Cultural Center and

15379-462: The clay actually does not vitrify and Bunzlauer pottery is better categorized as high-fired earthenware. In order to make their pottery watertight, Bunzlauer potters applied a coating of liquid clay, or slip. When fired, the slip glaze varied from a chocolate to dark brown. Since the fabric of Bunzlauer ware retains some porosity, the pottery conveniently has been suited for cooking over an open fire or for baking in an oven, as well as for storage. There

15548-517: The concentrations of nitric and sulfuric acid has decreased in presence of rainwater, which may be due to the significant increase in ammonium (most likely as ammonia from livestock production), which acts as a buffer in acid rain and raises the pH. The Köppen classification depends on average monthly values of temperature and precipitation. The most commonly used form of the Köppen classification has five primary types labeled A through E. Specifically,

15717-403: The confrontation between the siblings was mainly instigated by Władysław II's wife, Agnes of Babenberg, who believed that her husband, as the eldest son, was the rightful sole ruler of the whole country. On the other hand, Salomea of Berg , widow of Bolesław III and Władysław II's stepmother, attempted to form alliances with foreign rulers and took every opportunity to secure the reign of her sons,

15886-612: The contiguous United States, total annual precipitation increased at an average rate of 6.1 percent since 1900, with the greatest increases within the East North Central climate region (11.6 percent per century) and the South (11.1 percent). Hawaii was the only region to show a decrease (−9.25 percent). Analysis of 65 years of United States of America rainfall records show the lower 48 states have an increase in heavy downpours since 1950. The largest increases are in

16055-710: The course of the week, the likelihood of rain increases: it peaks by Saturday, after five days of weekday pollution has been built up. In heavily populated areas that are near the coast, such as the United States' Eastern Seaboard , the effect can be dramatic: there is a 22% higher chance of rain on Saturdays than on Mondays. The urban heat island effect warms cities 0.6 to 5.6 °C (33.1 to 42.1 °F) above surrounding suburbs and rural areas. This extra heat leads to greater upward motion, which can induce additional shower and thunderstorm activity. Rainfall rates downwind of cities are increased between 48% and 116%. Partly as

16224-412: The crystal and neighboring water droplets. This process is temperature dependent, as supercooled water droplets only exist in a cloud that is below freezing. In addition, because of the great temperature difference between cloud and ground level, these ice crystals may melt as they fall and become rain. Raindrops have sizes ranging from 0.1 to 9 mm (0.0039 to 0.3543 in) mean diameter but develop

16393-583: The current Orla street, was intended for approximately 650 non-Jewish prisoners, mostly Poles, but also citizens of the Soviet Union and other countries. They worked and lived at the Concordia factory, producing parts for combat aircraft. As Soviet army units were approaching the city, on February 11, 1945, prisoners from both camps who were able to walk were evacuated by the Germans in a death march to

16562-729: The death of Salomea of Berg in 1144. It seemed that a victory for the High Duke - thanks to his military predominance - was just a matter of time. In fact, Władysław II was so confident of winning at home that he sent Bolesław to aid Grand Prince Vsevolod II during a revolt in Kiev. Unfortunately, Bolesław's expedition ended in complete disaster, as the Grand Prince's death from disease created general confusion in Kiev. Then in 1146, Bolesław had to return quickly to Poland to help his father. The few troops which he recruited were not enough to stop

16731-498: The demarcation of dominant estates, the zonal boundary turned into a linear boundary on the Kwisa and the Bóbr, finally shaped at the turn of the 12th and 13th centuries. The western border of Silesia then became the Kwisa. According to legends, Bolesławiec was supposed to have been founded in the 10th century, during the reign of Mieszko I. In the area of the present-day Old Town, there were supposed to be three inns serving travellers on

16900-545: The descendants of Władysław II their inheritance over Silesia . By an agreement signed in Nuremberg , Germany, Bolesław IV agreed to accept the return of the exiled princes. He did so because, after the death of Władysław II, his sons could not directly challenge his authority as the senior duke, and they had not yet established any support within Poland. In addition, seating them would satisfy Barbarossa and thus keep him away from Poland. However Bolesław IV decided to maintain

17069-559: The descending and generally warming, leeward side where a rain shadow is observed. In Hawaii , Mount Waiʻaleʻale , on the island of Kauai, is notable for its extreme rainfall, as it is amongst the places in the world with the highest levels of rainfall, with 9,500 mm (373 in). Systems known as Kona storms affect the state with heavy rains between October and April. Local climates vary considerably on each island due to their topography, divisible into windward ( Koʻolau ) and leeward ( Kona ) regions based upon location relative to

17238-583: The duchies of Racibórz (granted to Mieszko) and Opole (to Jarosław). Four years later, it seemed that Bolesław was an alien from Mars the main objective of his life, the recovery of the Seniorate Province, and with this the title of high duke. He conspired with his uncle Casimir II the Just and his cousin Odon (Mieszko III's eldest son) to deprive Mieszko III the Old of the government. The coup gained

17407-529: The early medieval period was poorly developed. In fact, the functioning of a fortified settlement was only attested in Otoku, the existence of a fortified settlement in Łagów on the Kwisa River seems less likely. The existence of a stronghold in Bolesławice is admitted in some works. These were probably one of the southernmost Bobrzanski (Dziadoszanski) castles, whose communication with the main settlement centre

17576-735: The economic development of the duchy, and was continued by his son Henry I the Bearded . Bolesław founded the Cistercian Abbatia Lubensis abbey in Lubiąż with the collaboration of monks from Pforta , across the Saale River in Thuringia . Later the abbey became the Silesian ducal burial place. To safeguard his lands from other Piast princes, Bolesław obtained a protective bull from Pope Innocent III in 1198. There

17745-477: The emperor's treatment of his father, Bolesław remained at the side of the emperor, participating in his many wars. From 1158 to 1162 he took part in the Barbarossa's expedition to Italy, where he won fame after killing a well-known Italian knight in a duel on the walls of Milan . Bolesław's faithful service to the emperor was finally rewarded in 1163, when Barbarossa succeeded through diplomacy in restoring to

17914-604: The exile would just be for a few months, thanks to the family connections of Duchess Agnes; however, their hurried and insufficiently prepared expedition failed to cross the Oder River , and ultimately failed because of strong opposition from Władysław II's former subjects and problems Conrad III had within Germany as a result of his extended travels. The king gave Władysław II and his family the town of Altenburg in Saxony . This

18083-475: The existence of St Jadwiga's Church and the so-called Funeral Church, which was located in the cemetery in today's Garncarska Street. From the 14th century we also have the first information about a wooden town hall existing in Bolesławiec. Jews probably lived in Boleslawiec as early as 1190, when the burghers lent a certain amount of money, necessary for the construction of the city walls. In return, they were given their own street and synagogue[3][4]. Bolesławiec

18252-554: The existence of a larger settlement cluster between Szprotawa and Nowogród Bobrzański; it occupied an area of 350–400 km². It is in this area that most researchers situate the Bobrzan settlements. Therefore, Ilua (Iława), mentioned in Thietmar's chronicle, would have been the capital city of the Bobrzans and the settlement of this tribe would have been concentrated around it. Thus, they would have been some small territorial unit of

18421-511: The formation of a low-level barrier jet . Bands of thunderstorms can form with sea breeze and land breeze boundaries if enough moisture is present. If sea breeze rainbands become active enough just ahead of a cold front, they can mask the location of the cold front itself. Once a cyclone occludes an occluded front (a trough of warm air aloft) will be caused by strong southerly winds on its eastern periphery rotating aloft around its northeast, and ultimately northwestern, periphery (also termed

18590-482: The front is unstable enough for convection. Banding within the comma head precipitation pattern of an extratropical cyclone can yield significant amounts of rain. Behind extratropical cyclones during fall and winter, rainbands can form downwind of relative warm bodies of water such as the Great Lakes . Downwind of islands, bands of showers and thunderstorms can develop due to low-level wind convergence downwind of

18759-596: The general rebellion against Władysław II, who was completely defeated by the Junior Dukes. The deposed High Duke and his family initially escaped to the Prague court of Duke Vladislav II of Bohemia . After a short time in Bohemia, Władysław II and his family moved to Germany, where his brother-in-law, King Conrad III , offered his hospitality and assistance toward the high duke's restoration. At first, it seemed that

18928-400: The ground. This is termed virga and is more often seen in hot and dry climates. Stratiform (a broad shield of precipitation with a relatively similar intensity) and dynamic precipitation (convective precipitation which is showery in nature with large changes in intensity over short distances) occur as a consequence of slow ascent of air in synoptic systems (on the order of cm/s), such as in

19097-552: The higher mountains. Windward sides face the east to northeast trade winds and receive much more rainfall; leeward sides are drier and sunnier, with less rain and less cloud cover. In South America, the Andes mountain range blocks Pacific moisture that arrives in that continent, resulting in a desert-like climate just downwind across western Argentina. The Sierra Nevada range creates the same effect in North America forming

19266-438: The inner cylinder is filled, the amount inside it is discarded, then filled with the remaining rainfall in the outer cylinder until all the fluid in the outer cylinder is gone, adding to the overall total until the outer cylinder is empty. Other types of gauges include the popular wedge gauge (the cheapest rain gauge and most fragile), the tipping bucket rain gauge, and the weighing rain gauge. For those looking to measure rainfall

19435-518: The interior of St Mary's Church, during which it took on its current Baroque shape. In the 18th century, one of two main routes connecting Warsaw and Dresden ran through the town, and Kings Augustus II the Strong and Augustus III of Poland often traveled that route. During the Silesian Wars , the town came under Prussian rule. In 1745, a graphic depicting the city of that time in detail

19604-422: The island edges. Offshore California , this has been noted in the wake of cold fronts. Rainbands within tropical cyclones are curved in orientation. Tropical cyclone rainbands contain showers and thunderstorms that, together with the eyewall and the eye, constitute a hurricane or tropical storm . The extent of rainbands around a tropical cyclone can help determine the cyclone's intensity. The phrase acid rain

19773-415: The junior dukes. She feared that they would be relegated from their positions to make way for Władysław II's sons, the young Bolesław and his brothers Mieszko Tanglefoot and Konrad . The conflict erupted in 1141, when Salomea of Berg, without the knowledge of the high duke, decided to leave the land of Łęczyca , her dower , to her sons and tried to give her youngest daughter, Agnes, in marriage to one of

19942-601: The kind found in Lusatia and the Elbe Serbs, among others. Their tribe may have separated during the territorial development of the Dziadoszans, by whom they were reabsorbed. In political terms, therefore, the Bobrzans were not a tribe, but part of a wider unit. The area around Bolesławiec is covered by an extensive primeval forest, well attested by sources. Archaeological research has shown that settlement in this area in

20111-568: The leadership of his widow Sonja. Increasingly, individual potters and workshops began to mark their wares. Among the prominent names were those of Robert Burdack (who introduced a unique technique of ceramic intarsia inlay), Julius Paul, Hugo Reinhold, and Edwin Werner from Bunzlau and from the surrounding towns of Tillendorf (Bolesławice), Ullersdorf (Ołdrzychów), and Naumburg am Queis came Karl Werner, Gerhard Seiler, Hugo Reinwald, Max Lachmann, Bruno Vogt, and Hermann Kuehn. Boles%C5%82aw I

20280-427: The major Silesian cities handed back by the high duke and obtained full control over all Silesia. However Bolesław, as the eldest brother, held overall authority. Three years after taking control over Silesia, Bolesław felt strong enough to lead a retaliatory expedition against High Duke Bolesław IV to try and recover supremacy over Poland. Bolesław's exercise of overall power at the expense of his younger brother caused

20449-408: The market frontages and old town streets. The city was surrounded by a series of defensive walls with three city gates: "Upper" (at the end of ul. Sierpnia '80), "Mikołajska" (at the beginning of ul. Michała Kutuzowa) and "Dolna" (at the end of ul. Bolesława Prusa). The following are entered in the provincial register of monuments: other monuments: The Lower Silesian Way of Saint James runs through

20618-427: The maximum raindrop diameter together with fossil raindrop imprints has been used to constrain the density of the air 2.7 billion years ago. The sound of raindrops hitting water is caused by bubbles of air oscillating underwater . The METAR code for rain is RA, while the coding for rain showers is SHRA. In certain conditions, precipitation may fall from a cloud but then evaporate or sublime before reaching

20787-428: The most inexpensively, a can that is cylindrical with straight sides will act as a rain gauge if left out in the open, but its accuracy will depend on what ruler is used to measure the rain with. Any of the above rain gauges can be made at home, with enough know-how. When a precipitation measurement is made, various networks exist across the United States and elsewhere where rainfall measurements can be submitted through

20956-580: The most popular was the Pfauenauge ( peacock 's eye) design inspired by the Jugendstil decorators' fascination with the peacock's rich plumage. The Pfauenauge motif became the unofficial, but universally recognized, signature trademark for this category of German spongeware. By the beginning of the second decade of the new century, many of the potteries throughout the region had evolved into sophisticated ceramic studios, generally continuing to turn out

21125-472: The name of the city recorded in a document from 1196 - Boleslawez, giving its meaning Stadt des Boleslaw I (Polish: City of Bolesław I). The town, under the Latinized name castrum Boleslavec, is mentioned in a Latin document from 1277 signed by the Polish prince Bolesław (Latin: Boleslaus dux Polonie). In 1295, in the Latin chronicle Liber fundationis episcopatus Vratislaviensis, the town was mentioned under

21294-515: The neighboring districts of Lusatia and Saxony . Taken as a whole, Bunzlauer ware ranks among the most important folk pottery traditions in Europe. The area around Bolesławiec is rich in clays suited to the potter's wheel . Typically, utilitarian Bunzlauer pottery was turned on a kick wheel, dried leather-hard, dipped in a slip glaze and then burnt in a rectangular, cross-draft kiln . Although fired at temperatures of up to 1,320 degrees Celsius (2,410 °F) and often classified as stoneware ,

21463-634: The northern boundaries of the Prague bishopric are marked by the Trebouane (Trzebowians), Pobrane (Bobrzanians) and Dedosize (Dziadoszanians) tribes, which border the Miliczanians through the forest. Of these, only the Bobrzans could actually border the Miliczans. The name of this tribe clearly indicates that their headquarters should be sought on the Beaver River. Archaeological research has confirmed

21632-462: The number of heavy precipitation events over many areas during the past century, as well as an increase since the 1970s in the prevalence of droughts—especially in the tropics and subtropics. Changes in precipitation and evaporation over the oceans are suggested by the decreased salinity of mid- and high-latitude waters (implying more precipitation), along with increased salinity in lower latitudes (implying less precipitation and/or more evaporation). Over

21801-424: The old utilitarian brown-slip production but giving ever-increasing attention to their new line of colorful ware. Although new designs, many based upon the orientalizing forms popular at the time, were introduced, traditional shapes for coffee pots, bowls, and pitchers were retained but with their surfaces now brightened with a wide variety of popular Jugendstil patterns, particularly, that of the Pfauenauge. Even in

21970-592: The people of this culture in Silesia , Saxony , Lusatia and Greater Poland probably took place at this time. An ear pin with a decorated head was found from this period of the so-called Classic Phase of the Prolongation Culture in Bobrowice near Szprotawa. In turn, a bronze hatchet with a rim was found in Osiecznica, not far from Bolesławiec. Although traces of Lusatian people have been found on

22139-671: The people of this culture were assimilated by an incoming community using better bronze products. The most important archaeological culture of the Bronze Age was the Lusatian culture , preceded by the Pre-Lusatian culture , which, without losing its grave character, produced a whole range of local features. It was located between the Kaczawa River and the upper Beaver and Szprotawa Rivers. The settlement stabilisation of

22308-478: The precipitation regimes of places they impact, as they may bring much-needed precipitation to otherwise dry regions. Areas in their path can receive a year's worth of rainfall from a tropical cyclone passage. The fine particulate matter produced by car exhaust and other human sources of pollution forms cloud condensation nuclei leads to the production of clouds and increases the likelihood of rain. As commuters and commercial traffic cause pollution to build up over

22477-579: The primary types are A, tropical; B, dry; C, mild mid-latitude; D, cold mid-latitude; and E, polar. The five primary classifications can be further divided into secondary classifications such as rain forest , monsoon , tropical savanna , humid subtropical , humid continental , oceanic climate , Mediterranean climate , steppe , subarctic climate , tundra , polar ice cap , and desert . Rain forests are characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1,750 and 2,000 mm (69 and 79 in). A tropical savanna

22646-399: The rainfall time-structure n-index . The average time between occurrences of an event with a specified intensity and duration is called the return period . The intensity of a storm can be predicted for any return period and storm duration, from charts based on historic data for the location. The return period is often expressed as an n -year event. For instance, a 10-year storm describes

22815-509: The remains of a medieval castle, burnt down during the Thirty Years' War, and in whose place an Evangelical church was built ten years later. In the second half of the 18th century an orphanage was opened in Boleslawiec, the buildings of which are still preserved today in Bankowa Street. The orphanage had a printing press, which, among other things, published scientific works. In 1812, after the emancipation edict, Jews began to settle in

22984-409: The return of Władysław II to Poland. His successor was his energetic nephew Frederick Barbarossa , whose service Bolesław almost immediately joined. The first action of the new German ruler, however, was not to help Władysław II, but instead to march against Rome and be crowned emperor . Bolesław accompanied him. It was not until 1157 that the emperor finally organized an expedition against Poland. It

23153-428: The return period (assuming the probability remains the same for each year). For instance, a 10-year storm has a probability of occurring of 10 percent in any given year, and a 100-year storm occurs with a 1 percent probability in a year. As with all probability events, it is possible, though improbable, to have multiple 100-year storms in a single year. The Quantitative Precipitation Forecast (abbreviated QPF)

23322-442: The rising air motion of a large-scale flow of moist air across the mountain ridge, resulting in adiabatic cooling and condensation. In mountainous parts of the world subjected to relatively consistent winds (for example, the trade winds ), a more moist climate usually prevails on the windward side of a mountain than on the leeward or downwind side. Moisture is removed by orographic lift, leaving drier air (see katabatic wind ) on

23491-403: The route between Dresden and Wrocław, and there was supposed to be a defensive stronghold near these inns. Archaeological research in 2009 proved that there was a fortified settlement in the northern part of present-day Bolesławiec, on Topolowa Street, as early as the end of the 9th century[2], which suggests that there is a grain of truth in the legend of the three inns. According to the records of

23660-494: The security of his lands and retain the control over the main Silesian cities of Wroclaw , Opole , Racibórz , Głogów , and Legnica . After almost 16 years of exile, Bolesław returned to Silesia with his second wife, Christina (Zvenislava had died around 1155); his elder children, Jarosław and Olga; and his younger brother Mieszko Tanglefoot . The youngest brother, Konrad , remained in Germany. Bolesław and Mieszko initially ruled jointly and two years later (1165) both retook

23829-400: The so-called Sukow-Szeligii culture, which covered, inter alia, Western Pomerania, Mecklenburg, Brandenburg, Lusatia, Płock Mazovia, Greater Poland, Silesia and probably temporarily southern Lesser Poland. It occurred in the northern areas of Lower Silesia near Ślęza. The settlement situation in the Bolesławiec area in the 8th century is similarly unclear. According to some researchers, this area

23998-442: The sons of Grand Prince Vsevolod II Olgovich of Kiev . Władysław II was faster, however, and he gave Grand Prince Vsevolod II several additional political advantages, including a marriage between Bolesław and Vsevolod II's daughter, Zvenislava , which took place in 1142. The Polish-Ruthenian alliance soon proved to be extremely important in the struggle between Władysław II and the Junior Dukes. The final conflicts took place after

24167-452: The studio wares, the blend of folk art and high art is curious and charming, with many of the new and decorative elements taking on a decidedly "country" appearance. This is true for the production of the art potter, Friedrich Festersen (1880–1915), born in northern Schleswig , who opened his Kunsttöpferei Friedrich Festersen in Berlin in 1909 at about the same time that the peacock's eye motif

24336-503: The support of Lesser Poland , which was mastered by Casimir and shortly afterwards Greater Poland sided with Odon. Bolesław, however, suffered a sudden and surprising defeat at the hands of his brother Mieszko and his son Jarosław who had allied with Mieszko III. This left the way free for Casimir II to be proclaimed High Duke, and Bolesław again had to escape to Germany. Thanks to the mediation of Casimir II, Bolesław returned to his Duchy without major troubles in 1177; however, he suffered

24505-490: The synagogue was set on fire. During the war, Nazi propaganda plays were staged in the Bolesławiec theater for some time, and the people of Bolesławiec fought, among others, during the invasion of Poland . Polish forced laborers worked around the city. During the war, the parish priest of St. Mary's Church, Father Paul Sauer, spoke out against the Nazis' actions. During World War II , the Germans established two subcamps of

24674-462: The time), where few flint wares were found. The people living in the Beaver basin at that time arrived here at the end of the Palaeolithic from the so-called Federmesser and Ahrensburg cultures. After the climate warmed up, the remaining population here participated in the emergence of a Mesolithic community, referred to as the Protocomornic group. After further warming, however, they left

24843-779: The town again. In 1823, a prayer room was set up in the house of the widow Böhm at the then Kirchplatz Napoleon Bonaparte visited the town six times during the Napoleonic wars, and Mikhail Kutuzov, the Russian Field Marshal, died here on 28 April 1813. The house in which he died has been presenved to this day and now houses the City History Department of the Boleslawiec Ceramics Museum. A few months after his death, in August 1813

25012-673: The troops of the 52nd Army belonging to the 1st Ukrainian Front. The city was seriously damaged by the Soviets after the capitulation of the Third Reich. Robberies, rapes and arson were common back then and Bolesławiec lost many monuments irretrievably. Almost all historic tenement houses standing on the town square were burned down, almost all former Dominican buildings on today's Armii Krajowej Street were destroyed, as well as many beautiful tenement houses and public buildings. City cemeteries were desecrated and destroyed, but St. Mary's Church

25181-429: The tropics since the 1970s. Globally there has been no statistically significant overall trend in precipitation over the past century, although trends have varied widely by region and over time. Eastern portions of North and South America, northern Europe, and northern and central Asia have become wetter. The Sahel, the Mediterranean, southern Africa and parts of southern Asia have become drier. There has been an increase in

25350-543: The vicinity of cold fronts and near and poleward of surface warm fronts . Similar ascent is seen around tropical cyclones outside the eyewall , and in comma-head precipitation patterns around mid-latitude cyclones . A wide variety of weather can be found along an occluded front, with thunderstorms possible, but usually, their passage is associated with a drying of the air mass. Occluded fronts usually form around mature low-pressure areas. What separates rainfall from other precipitation types, such as ice pellets and snow,

25519-408: The warm conveyor belt), forcing a surface trough to continue into the cold sector on a similar curve to the occluded front. The front creates the portion of an occluded cyclone known as its comma head , due to the comma -like shape of the mid-tropospheric cloudiness that accompanies the feature. It can also be the focus of locally heavy precipitation, with thunderstorms possible if the atmosphere along

25688-555: The water droplets in a cloud to remain stationary. When air turbulence occurs, water droplets collide, producing larger droplets. As these larger water droplets descend, coalescence continues, so that drops become heavy enough to overcome air resistance and fall as rain. Coalescence generally happens most often in clouds above freezing (in their top) and is also known as the warm rain process. In clouds below freezing, when ice crystals gain enough mass they begin to fall. This generally requires more mass than coalescence when occurring between

25857-424: The whole of Boleslawiec was burnt down. The town was conquered as a result of the treachery of one of the townsmen, who set fire to the Upper Gate, located near the present-day Okrąglak on Piłsudski Square. Bolesławiec faced many years of reconstruction after these events. In 1454, the Jews were expelled from the city[6]. From 1469 to 1490 it was under the rule of Hungary , before falling back to Bohemia, then ruled by

26026-688: Was a reconciliation between Bolesław and his eldest son, Jarosław, who was elected bishop of Wrocław . This enabled him, after Jarosław's death on 22 March 1201, to inherit Opole, which was again reunited with his lands. Bolesław survived his son by only nine months, however, and died on 7 or 8 December 1201 in his castle in Leśnica  [ pl ] , west of Wrocław. He was buried in the Lubiąż Cistercian monastery which he had founded. In 1142 Bolesław married his first wife Zvenislava (d. ca. 1155), daughter of Grand Prince Vsevolod II Olgovich of Kiev. They had two children: By 1157, Bolesław married his second wife Christina (d. 21 February 1204/1208),

26195-458: Was beginning to embellish the ceramics of Bunzlau. Festersen's connection with the Bunzlauer potteries is uncertain but the peacock's eye motif is to be found throughout the production of his studio. There is no evidence that Festersen turned himself and the potters he employed may have come from Bunzlau, bringing the fashionable new designs with them. Although Festersen was a casualty of the First World War , his art pottery survived until 1922 under

26364-426: Was created by Friedrich Werner. It shows that the town occupied only a small part of its present area, bounded by medieval fortification walls. In the centre was the market square with the town hall, to the right of which was the parish church, the present basilica. The city had three gates - the Upper Gate (the area of today's Piłsudski Square), the Lower Gate (the area of today's Thermal Baths in Zgorzelecka Street) and

26533-494: Was first used by Scottish chemist Robert Augus Smith in 1852. The pH of rain varies, especially due to its origin. On America's East Coast, rain that is derived from the Atlantic Ocean typically has a pH of 5.0–5.6; rain that comes across the continental from the west has a pH of 3.8–4.8; and local thunderstorms can have a pH as low as 2.0. Rain becomes acidic primarily due to the presence of two strong acids, sulfuric acid (H 2 SO 4 ) and nitric acid (HNO 3 ). Sulfuric acid

26702-454: Was intended as a temporary residence, but Władysław II would spend the rest of his life there. Tired of a tedious life in Altenburg, Bolesław traveled to the court of his protector, King Conrad III. With him, the young Polish prince extensively took part in German political affairs. In 1148 he joined in the Second Crusade with Conrad III, during which he visited Constantinople and the Holy Land . Conrad III died in 1152 without having secured

26871-412: Was located between 1226 and 1251, precisely in the area of the present Old Town. From this period we no longer have any information about the stronghold at Topolowa Street, which was probably abandoned. The town quickly became Germanised. In 1361, the number of Jewish inhabitants was 360. Jews owned 31 houses. They were engaged in petty trade, crafts, small services In 1392 Bolesławiec, then belonging to

27040-469: Was met when, at the turn of the century, Bunzlauer pottery underwent a colorful transformation and a new chapter in its history was opened. During the first decades of the 20th century, pot shops throughout Silesia and neighboring Lusatia began to decorate their wares with imaginative organic motifs derived from the contemporary Jugendstil aesthetic and applied by brush or, more often, with the aid of cut sponges. Floral designs were common embellishments, but

27209-430: Was not until 1138, after the death of Bolesław III, that he moved with his parents to Kraków , which became the capital of the Seniorate Province , ruled by his father as high duke and overlord of Poland. The reign of Władysław II was short and extremely stormy. The conflicts began when the high duke tried to remove his half-brothers, the junior dukes, from their districts. According to the chronicler Wincenty Kadłubek ,

27378-644: Was officially approved in 1946.

27547-578: Was opened in Bolesławiec. Changes in Bolesławiec took place after Adolf Hitler took power in the Reich. The current Bolesława Chrobrego Street was named Adolf Hitler Strasse, and the NSDAP and Gestapo were established in the city. In April 1933, a boycott of Jewish stores in the city was carried out - uniformed SA officers took photos of people who wanted to shop there. After the Nuremberg Laws came into force, Jews were removed from state positions, organizations and associations. During Kristallnacht on November 9–10, 1938, Jewish businesses were looted and

27716-414: Was part of the Tornow-Klenica zone, which included part of Lusatia, the Lubusz Land , part of Greater Poland and the northern territories of Lower Silesia. As before, sites confirming that Bolesławiec belonged to this zone have not yet been discovered. The first finds confirming the existence of a settlement in Bolesławiec at the turn of the 8th and 9th centuries are extremely valuable due to their form. This

27885-462: Was provided by the Bóbr and Kwisa rivers. A stronghold on the left bank in the area of Bolesławice, dated before the middle of the 10th century, was located by German archaeologists in the pre-war period as part of surface research. A new survey in 1960 failed to locate the fortress. Thus, the assumption was made that it was completely destroyed at that time. More recent works no longer deal with this fortress, considering it, and probably rightly so, to be

28054-410: Was saved from a quagmire in the vicinity of Bolesławiec, and the founding of the church was for him the fulfilment of a vow he had made to God in a moment of danger. In the 13th century a Dominican monastery was also founded in the area of today's Armii Krajowej and Teatralna Streets, at the crossroads of today's Prusa and Zgorzelecka Streets there was Our Dear Lady's Church, we also have information about

28223-448: Was saved from this fate. After the Potsdam Conference, its German inhabitants were expelled from the city and replaced by displaced persons from the Eastern Borderlands and repatriates from Yugoslavia and France. Numerous Red Army troops were stationed near Bolesławiec (Pstrąże, Świętoszów, Szczytnica, Karczmarka). The city was slowly rebuilt under Polish rule, but many historic tenement houses that could still be saved were demolished. This

28392-412: Was the fate of the tenement houses on Asnyka Street, which were replaced by apartment blocks. We managed to prevent the demolition of the former Evangelical church, which was eventually taken over and renovated by the Roman Catholic Church. Gradually, the city began to expand again - the southern part of the large village of Bolesławice was absorbed and new housing estates were created in the eastern part of

28561-408: Was to establish a settlement on the site of the present-day Old Town. It is very possible that St Dorothy's Church was already founded at that time, and over time it was replaced by the present Church of the Assumption of the Blessed Virgin Mary and St Nicholas, which is now a minor basilica. According to another legend, it was supposed to be built thanks to the foundation of a merchant from Wrocław, who
