128-583: Ancient Medieval Modern Iraqi Kurdistan or Southern Kurdistan ( Kurdish : باشووری کوردستان , romanized : Başûrê Kurdistanê ) is an unofficial term commonly used within Kurdish nationalist circles when referring to a roughly defined area in northern Iraq inhabited by Kurdish-speaking people. The proponents of Kurdish nationalism consider Iraqi Kurdistan, together with Turkish Kurdistan , Syrian Kurdistan , and Iranian Kurdistan as collectively forming Greater Kurdistan . Much of
256-633: A glacier may form. Otherwise, snow typically melts seasonally, causing runoff into streams and rivers and recharging groundwater . Major snow-prone areas include the polar regions , the northernmost half of the Northern Hemisphere and mountainous regions worldwide with sufficient moisture and cold temperatures. In the Southern Hemisphere , snow is confined primarily to mountainous areas, apart from Antarctica . Snow affects such human activities as transportation : creating

The strong convection that develops has enough moisture to produce whiteout conditions at places which the line passes over as the wind causes intense blowing snow. This type of snowsquall generally lasts less than 30 minutes at any point along its path, but the motion of the line can cover large distances. Frontal squalls may form
512-830: A 1968 coup by the Ba'ath Party . The Ba'ath government started a campaign to end the Kurdish insurrection, which stalled in 1969. This can be partly attributed to the internal power struggle in Baghdad and also tensions with Iran. Moreover, the Soviet Union pressured the Iraqis to come to terms with Barzani. A peace plan was announced in March 1970 and provided for broader Kurdish autonomy. The plan also gave Kurds representation in government bodies, to be implemented in four years. Despite this,
640-534: A Kurdish rebellion against Iraq, and though defeated within several months, the movement gained a major importance in the Kurdish struggle later on, creating the ground for such a notable Kurdish rebel as Mustafa Barzani . During World War II, the power vacuum in Iraq was exploited by the Kurdish tribes and under the leadership of Mustafa Barzani a rebellion broke out in the north, effectively gaining control of Kurdish areas until 1945, when Iraqis could once again subdue
768-507: A ceasefire in February 1964 which provoked a split among Kurdish urban radicals on one hand and Peshmerga (Freedom fighters) forces led by Barzani on the other. Barzani agreed to the ceasefire and fired the radicals from the party. Following the unexpected death of Arif, whereupon he was replaced by his brother, Abdul Rahman Arif , the Iraqi government launched a last-ditch effort to defeat
896-433: A cirque (corrie or cwm), a typically armchair-shaped geological feature, which collects snow and where the snowpack compacts under the weight of successive layers of accumulating snow, forming névé. Further crushing of the individual snow crystals and reduction of entrapped air in the snow turns it into glacial ice. This glacial ice will fill the cirque until it overflows through a geological weakness or an escape route, such as
1024-649: A crystal morphology diagram, relating crystal shapes to the temperature and moisture conditions under which they formed, which is summarized in the following table. Dendrites Hollow prisms Needles Solid plates Dendrites Solid plates Prisms Nakaya discovered that the shape is also a function of whether the prevalent moisture is above or below saturation. Forms below the saturation line tend more toward solid and compact while crystals formed in supersaturated air tend more toward lacy, delicate, and ornate. Many more complex growth patterns also form, which include side-planes, bullet-rosettes, and planar types, depending on
1152-428: A dialect of Southern Kurdish or as a fourth language under Kurdish is a matter of debate, but the differences between Laki and other Southern Kurdish dialects are minimal. The literary output in Kurdish was mostly confined to poetry until the early 20th century, when more general literature became developed. Today, the two principal written Kurdish dialects are Kurmanji and Sorani. Sorani is, along with Arabic , one of
1280-447: A droplet has frozen, it grows in the supersaturated environment—one where air is saturated with respect to ice when the temperature is below the freezing point. The droplet then grows by diffusion of water molecules in the air (vapor) onto the ice crystal surface where they are collected. Because water droplets are so much more numerous than the ice crystals, the crystals are able to grow to hundreds of micrometers or millimeters in size at
1408-589: A few molecules in the droplet need to get together by chance to form an arrangement similar to that in an ice lattice. The droplet freezes around this "nucleus". In warmer clouds, an aerosol particle or "ice nucleus" must be present in (or in contact with) the droplet to act as a nucleus. Ice nuclei are very rare compared to cloud condensation nuclei on which liquid droplets form. Clays, desert dust, and biological particles can be nuclei. Artificial nuclei include particles of silver iodide and dry ice , and these are used to stimulate precipitation in cloud seeding . Once

In the Northern Hemisphere, the northern side of the low-pressure area produces the most snow. For the southern mid-latitudes , the side of a cyclone that produces the most snow is the southern side. A cold front , the leading edge of a cooler mass of air, can produce frontal snowsqualls —an intense frontal convective line (similar to
1664-485: A highly porous, sintered material made up of a continuous ice structure and a continuously connected pore space, forming together the snow microstructure". Almost always near its melting temperature, a snowpack is continually transforming these properties wherein all three phases of water may coexist, including liquid water partially filling the pore space. After deposition, snow progresses on one of two paths that determine its fate, either by ablation (mostly by melting) from
1792-470: A larger weather system. The physics of snow crystal development in clouds results from a complex set of variables that include moisture content and temperatures. The resulting shapes of the falling and fallen crystals can be classified into a number of basic shapes and combinations thereof. Occasionally, some plate-like, dendritic and stellar-shaped snowflakes can form under clear sky with a very cold temperature inversion present. Snow clouds usually occur in
1920-435: A minimum extent of 2 million square kilometres (0.77 × 10 ^ sq mi) each August to a maximum extent of 45 million square kilometres (17 × 10 ^ sq mi) each January or nearly half of the land surface in that hemisphere. A study of Northern Hemisphere snow cover extent for the period 1972–2006 suggests a reduction of 0.5 million square kilometres (0.19 × 10 ^ sq mi) over
2048-530: A mountain range results in adiabatic cooling, and ultimately condensation and precipitation. Moisture is gradually removed from the air by this process, leaving drier and warmer air on the descending, or leeward , side. The resulting enhanced snowfall, along with the decrease in temperature with elevation, combine to increase snow depth and seasonal persistence of snowpack in snow-prone areas. Mountain waves have also been found to help enhance precipitation amounts downwind of mountain ranges by enhancing
2176-488: A series of snow events, punctuated by freezing and thawing, over areas that are cold enough to retain snow seasonally or perennially. Major snow-prone areas include the Arctic and Antarctic , the Northern Hemisphere, and alpine regions. The liquid equivalent of snowfall may be evaluated using a snow gauge or with a standard rain gauge , adjusted for winter by removal of a funnel and inner cylinder. Both types of gauges melt
2304-409: A short distance ahead of the surface cold front or behind the cold front where there may be a deepening low-pressure system or a series of trough lines which act similar to a traditional cold frontal passage. In situations where squalls develop post-frontally, it is not unusual to have two or three linear squall bands pass in rapid succession separated only by 25 miles (40 kilometers), with each passing
2432-419: A snow fall or seasonal snowpack, or by transitioning from firn (multi-year snow) into glacier ice . Over the course of time, a snowpack may settle under its own weight until its density is approximately 30% of water. Increases in density above this initial compression occur primarily by melting and refreezing, caused by temperatures above freezing or by direct solar radiation. In colder climates, snow lies on
2560-608: A snowpack can create flow fingers and ponding or flow along capillary barriers, which can refreeze into horizontal and vertical solid ice formations within the snowpack. Among the measurements of the properties of snowpacks that the International Classification for Seasonal Snow on the Ground includes are: snow height, snow water equivalent, snow strength, and extent of snow cover. Each has a designation with code and detailed description. The classification extends
2688-416: A snowslide or snowslip) is a rapid flow of snow down a sloping surface. Avalanches are typically triggered in a starting zone from a mechanical failure in the snowpack (slab avalanche) when the forces on the snow exceed its strength but sometimes only with gradually widening (loose snow avalanche). After initiation, avalanches usually accelerate rapidly and grow in mass and volume as they entrain more snow. If
SECTION 20
#17327984658352816-630: A substance denser than névé , yet less dense and hard than glacial ice . Firn resembles caked sugar and is very resistant to shovelling. Its density generally ranges from 550 to 830 kilograms per cubic metre (34 to 52 lb/cu ft), and it can often be found underneath the snow that accumulates at the head of a glacier . The minimum altitude that firn accumulates on a glacier is called the firn limit , firn line or snowline . There are four main mechanisms for movement of deposited snow: drifting of unsintered snow, avalanches of accumulated snow on steep slopes, snowmelt during thaw conditions, and
2944-576: A third uprising which was suppressed with British air and ground forces. By 1927, the Barzani clan had become vocal supporters of Kurdish rights in Iraq. In 1929, the Barzani demanded the formation of a Kurdish province in northern Iraq. Emboldened by these demands, in 1931 Kurdish notables petitioned the League of Nations to set up an independent Kurdish government. In late 1931, Ahmed Barzani initiated
3072-510: A variety that was an important literary language since the 14th century, but it was replaced by Central Kurdish in the 20th century. European scholars have maintained that Gorani is separate from Kurdish and that Kurdish is synonymous with the Northern Kurdish group, whereas ethnic Kurds maintain that Kurdish encompasses any of the unique languages or dialects spoken by Kurds that are not spoken by neighbouring ethnic groups. Gorani
3200-624: Is "Land of Kurds". The name was also formerly spelled Curdistan . One of the ancient names of Kurdistan is Corduene . Iraqi Kurdistan is largely mountainous, with the highest point being a 3,611 m (11,847 ft) point known locally as Cheekha Dar ("black tent"). Mountains in Iraqi Kurdistan include the Zagros , Sinjar Mountains , Hamrin Mountains , Mount Nisir and Qandil mountains . There are many rivers running through
3328-472: Is "the transformation that the snow undergoes in the period from deposition to either melting or passage to glacial ice". Starting as a powdery deposition, snow becomes more granular when it begins to compact under its own weight, be blown by the wind, sinter particles together and commence the cycle of melting and refreezing. Water vapor plays a role as it deposits ice crystals, known as hoar frost , during cold, still conditions. During this transition, snow "is
3456-565: Is a Northwestern Iranian language or group of languages spoken by Kurds in the region of Kurdistan , namely in southeast Turkey , northern Iraq , northwest Iran , and northern Syria . It is also spoken in northeast Iran, as well as in certain areas of Armenia and Azerbaijan . Kurdish varieties constitute a dialect continuum , with some mutually unintelligible varieties, and collectively have 26 million native speakers. The main varieties of Kurdish are Kurmanji , Sorani , and Southern Kurdish ( Xwarîn ). The majority of

Before August 2002, the Turkish government placed severe restrictions on the use of Kurdish, prohibiting the language in education and broadcast media. In March 2006, Turkey allowed private television channels to begin airing programming in Kurdish. However,

The Zaza language , spoken mainly in Turkey, differs both grammatically and in vocabulary and is generally not understandable by Gorani speakers but it is considered related to Gorani. Almost all Zaza-speaking communities, as well as speakers of the closely related Shabaki dialect spoken in parts of Iraqi Kurdistan , identify themselves as ethnic Kurds. Geoffrey Haig and Ergin Öpengin in their recent study suggest grouping

The same source classifies different Kurdish dialects as two main groups, northern and central. The average Kurmanji speaker does not find it easy to communicate with the inhabitants of Sulaymaniyah or Halabja . Some linguistic scholars assert that the term "Kurdish" has been applied extrinsically in describing

In Kyrgyzstan , 96.21% of the Kurdish population speak Kurdish as their native language. In Kazakhstan, the corresponding percentage is 88.7%. Snowfall Snow comprises individual ice crystals that grow while suspended in
4480-464: Is termed ocean-effect or bay-effect snow . The effect is enhanced when the moving air mass is uplifted by the orographic influence of higher elevations on the downwind shores. This uplifting can produce narrow but very intense bands of precipitation which may deposit at a rate of many inches of snow each hour, often resulting in a large amount of total snowfall. The areas affected by lake-effect snow are called snowbelts . These include areas east of

The Baath party under Saddam Hussein engaged in active expulsion of minorities from the mid-1970s onwards. In 1978 and 1979, 600 Kurdish villages were burned down and around 200,000 Kurds were deported to the other parts of the country. The campaigns took place during the Iraqi–Kurdish conflict , being largely motivated by

Kurdish military forces, known as Peshmerga , played an important role in the overthrow of the Iraqi government; however, Kurds have been reluctant to send troops into Baghdad since then, preferring not to be dragged into the sectarian struggle that dominates much of Iraq. A new constitution of Iraq was established in 2005, defining Iraq as a federalist state consisting of Regions and Governorate's. The Kurdistan region includes
6528-614: The Iraqi government embarked on an Arabization program in the oil rich regions of Kirkuk and Khanaqin in the same period. In the following years, Baghdad government overcame its internal divisions and concluded a treaty of friendship with the Soviet Union in April 1972 and ended its isolation within the Arab world. On the other hand, Kurds remained dependent on the Iranian military support and could do little to strengthen their forces. In 1973,

The Baathist policies motivating those events are sometimes referred to as "internal colonialism", described by Dr. Francis Kofi Abiew as a "Colonial 'Arabization ' " program, including large-scale Kurdish deportations and forced Arab settlement in
7168-497: The Kurdistan Regional Government. Tensions between Iraqi Kurdistan and the central Iraqi government mounted through 2011–2012 on the issues of power sharing, oil production and territorial control. In April 2012, the president of Iraq's semi-autonomous northern Kurdish region demanded that officials agree to their demands or face the prospect of secession from Baghdad by September 2012. In September 2012,

9600-475: The context of larger weather systems, the most important of which is the low-pressure area, which typically incorporate warm and cold fronts as part of their circulation. Two additional and locally productive sources of snow are lake-effect (also sea-effect) storms and elevation effects, especially in mountains. Mid-latitude cyclones are low-pressure areas which are capable of producing anything from cloudiness and mild snow storms to heavy blizzards . During
9728-544: The contribution of snowmelt to river hydraulics and ground hydrology . In doing so, they employ a variety of instruments to observe and measure the phenomena studied. Their findings contribute to knowledge applied by engineers , who adapt vehicles and structures to snow, by agronomists , who address the availability of snowmelt to agriculture , and those, who design equipment for sporting activities on snow. Scientists develop and others employ snow classification systems that describe its physical properties at scales ranging from
9856-450: The crystal facets and hollows/imperfections mean that the crystals often appear white in color due to diffuse reflection of the whole spectrum of light by the small ice particles. Micrography of thousands of snowflakes from 1885 onward, starting with Wilson Alwyn Bentley , revealed the wide diversity of snowflakes within a classifiable set of patterns. Closely matching snow crystals have been observed. Ukichiro Nakaya developed
9984-520: The culture of the vine and the palm tree, and the other on water and the means of finding it out in unknown ground. He translated both from Kurdish into Arabic in the early 9th century AD. Among the earliest Kurdish religious texts is the Yazidi Black Book , the sacred book of Yazidi faith. It is considered to have been authored sometime in the 13th century AD by Hassan bin Adi (b. 1195 AD),
10112-553: The details. groups Kurdish with Zaza Gorani within a "Northwestern I" group, while Glottolog based on Encyclopædia Iranica prefers an areal grouping of "Central dialects" (or "Kermanic") within Northwest Iranic, with Kurdish but not Zaza-Gorani grouped with "Kermanic". Gorani is distinct from Northern and Central Kurdish, yet shares vocabulary with both of them and there are some grammatical similarities with Central Kurdish. The Hawrami dialects of Gorani includes
10240-446: The difficulty of measuring snowfall. Glaciers with their permanent snowpacks cover about 10% of the earth's surface, while seasonal snow covers about nine percent, mostly in the Northern Hemisphere, where seasonal snow covers about 40 million square kilometres (15 × 10 ^ sq mi), according to a 1987 estimate. A 2007 estimate of snow cover over the Northern Hemisphere suggested that, on average, snow cover ranges from
10368-583: The disintegration of the Ak Koyunlu , all of its territories including what is modern-day Iraqi Kurdistan passed to the Iranian Safavids in the earliest 16th century. Between the 16th and 17th century the area nowadays known as Iraqi Kurdistan, (formerly ruled by three principalities of Baban , Badinan , and Soran ) was continuously passed back and forth between archrivals the Safavids and
10496-504: The embargoes fueled tensions between the two dominant political parties, the KDP and the PUK, over control of trade routes and resources. Relations between the PUK and the KDP started to become dangerously strained from September 1993 after rounds of amalgamations occurred between parties. After 1996, 13% of the Iraqi oil sales were allocated for Iraqi Kurdistan and this led to relative prosperity in
10624-483: The expense of the water droplets by the Wegener–Bergeron–Findeisen process . These large crystals are an efficient source of precipitation, since they fall through the atmosphere due to their mass, and may collide and stick together in clusters, or aggregates. These aggregates are snowflakes , and are usually the type of ice particle that falls to the ground. Although the ice is clear, scattering of light by
10752-564: The fact that this usage reflects the sense of ethnic identity and unity among the Kurds. From a linguistic or at least a grammatical point of view, however, Kurmanji and Sorani differ as much from each other as English and German, and it would seem appropriate to refer to them as languages. For example, Sorani has neither gender nor case-endings, whereas Kurmanji has both.... Differences in vocabulary and pronunciation are not as great as between German and English, but they are still considerable. According to Encyclopaedia of Islam , although Kurdish
10880-493: The fifteenth century. From the 15th to 17th centuries, classical Kurdish poets and writers developed a literary language. The most notable classical Kurdish poets from this period were Ali Hariri , Ahmad Khani , Malaye Jaziri and Faqi Tayran . The Italian priest Maurizio Garzoni published the first Kurdish grammar titled Grammatica e Vocabolario della Lingua Kurda in Rome in 1787 after eighteen years of missionary work among
11008-643: The fight against ISIL. In November, Ed Royce , Chairman of the Foreign Affairs Committee of the United States House of Representatives, introduced legislation to arm the Kurds directly, rather than continue working through the local governments. In August 2014, the US began a campaign of airstrikes in Iraq, in part to protect Kurdish areas such as Erbil from the militants. Kurdish language Ancient Medieval Modern Kurdish ( Kurdî , کوردی )
11136-637: The four centuries of the Parthian era (247 BCE to 226 AD) the region was ruled by semi-independent principalities of Barzan and Sharazur, and in 1st century it was partially under the rule of the Jewish kingdom of Adiabene . Between 3rd and 4th centuries the region was ruled by the House of Kayus until it was incorporated into the Sassanian Empire in 380 AD and it was renamed to Nodshēragān. The region
11264-442: The gap between two mountains. When the mass of snow and ice is sufficiently thick, it begins to move due to a combination of surface slope, gravity and pressure. On steeper slopes, this can occur with as little as 15 m (49 ft) of snow-ice. Scientists study snow at a wide variety of scales that include the physics of chemical bonds and clouds ; the distribution, accumulation, metamorphosis, and ablation of snowpacks; and
11392-490: The geographical area of Iraqi Kurdistan is part of Kurdistan Region (KRI), a semi- autonomous region in the Republic of Iraq. Those areas not incorporated into KRI are referred to as “ disputed territories ”. Article 140 of the Iraqi constitution stipulates the mechanism for solving the dispute by a date not exceeding 31 December 2007, but this has not been implemented and remains an outstanding issue. Some have suggested that
11520-548: The government against the Kurds after the Algiers agreement led to renewed clashes between the Iraqi Army and Kurdish guerrillas in 1977. In 1978 and 1979, 600 Kurdish villages were burned down and around 200,000 Kurds were deported to the other parts of the country. The Ba'athist government of Iraq forcibly displaced and culturally Arabized minorities ( Kurds , Yezidis , Assyrians , Shabaks , Armenians , Turkmen , Mandeans ), in line with settler colonialist policies, from
11648-401: The government of Iraq has made it clear that it intends to never implement the article, but instead aims to dismantle Kurdistan Region altogether. As with the rest of Kurdistan, and unlike most of the rest of Iraq, the region is inland and mountainous. The exact origins of the name Kurd are unclear. The suffix -stan is an Iranian term for region. The literal translation for Kurdistan
11776-479: The governor of the villages and towns of Kurda. Kurda was reduced to a province centering around modern Sinjar. Erbil's name was Akkadianized to Arba-ilu and during the Neo-Assyrian Empire the city was noted for its distinctive cult of Ishtar . The region was partially under the rule of Urartu and the kingdom of Musasir in early 1st millennium BCE. Modern Rawandiz district was a religious center of
11904-524: The great-grandnephew of Sheikh Adi ibn Musafir (d. 1162), the founder of the faith. It contains the Yazidi account of the creation of the world, the origin of man, the story of Adam and Eve and the major prohibitions of the faith. According to The Cambridge History of the Kurds , "the first proper 'text'" written in Kurdish is a short Christian prayer. It was written in Armenian characters, and dates from
12032-453: The ground all winter. By late spring, snow densities typically reach a maximum of 50% of water. Snow that persists into summer evolves into névé , granular snow, which has been partially melted, refrozen and compacted. Névé has a minimum density of 500 kilograms per cubic metre (31 lb/cu ft), which is roughly half of the density of liquid water. Firn is snow that has persisted for multiple years and has been recrystallized into
12160-739: The head of the Kurdistan Democratic Party (KDP), which was granted legal status in 1960. By early 1960, it became apparent that Qasim would not follow through with his promise of regional autonomy. As a result, the KDP began to agitate for regional autonomy. In the face of growing Kurdish dissent, as well as Barzani's personal power, Qasim began to incite the Barzanis historical enemies, the Baradost and Zebari tribes, which led to intertribal warfare throughout 1960 and early 1961. By February 1961, Barzani had successfully defeated
12288-481: The independence for Iraqi Kurdistan, Turkey later gave signs that it could recognize an independent Kurdish state. On 11 July 2014, KRG forces seized control of the Bai Hassan and Kirkuk oilfields , prompting a condemnation from Baghdad and a threat of "dire consequences" if the oilfields were not relinquished back to Iraq's control. In September, Kurdish leaders decided to postpone the referendum so as to focus on
12416-445: The individual crystal to the aggregated snowpack. A sub-specialty is avalanches , which are of concern to engineers and outdoors sports people, alike. Snow science addresses how snow forms, its distribution, and processes affecting how snowpacks change over time. Scientists improve storm forecasting, study global snow cover and its effect on climate, glaciers, and water supplies around the world. The study includes physical properties of
12544-634: The inscriptions in this period are Mardaman , Azuhinum, Ninet (Nineveh), Arrapha , Urbilum , and Kurda . In early 2nd millennium the region was ruled by the Semitic-speaking kingdom of Kurda except for two decades in 18th century BCE when it was conquered by the Amorite Shamshi Adad and was incorporated into the Kingdom of Upper Mesopotamia. In 1760s BCE the kingdom of Kurda faced an invasion by Elam and Eshnunna during
12672-490: The language the Kurds speak, whereas some ethnic Kurds have used the word term to simply describe their ethnicity and refer to their language as Kurmanji , Sorani , Hewrami , Kermanshahi , Kalhori or whatever other dialect or language they speak. Some historians have noted that it is only recently that the Kurds who speak the Sorani dialect have begun referring to their language as Kurdî , in addition to their identity, which
12800-615: The lift needed for condensation and precipitation. A snowflake consists of roughly 10 water molecules which are added to its core at different rates and in different patterns depending on the changing temperature and humidity within the atmosphere that the snowflake falls through on its way to the ground. As a result, snowflakes differ from each other though they follow similar patterns. Snow crystals form when tiny supercooled cloud droplets (about 10 μm in diameter) freeze . These droplets are able to remain liquid at temperatures lower than −18 °C (0 °F), because to freeze,
12928-563: The material as it changes, bulk properties of in-place snow packs, and the aggregate properties of regions with snow cover. In doing so, they employ on-the-ground physical measurement techniques to establish ground truth and remote sensing techniques to develop understanding of snow-related processes over large areas. In the field snow scientists often excavate a snow pit within which to make basic measurements and observations. Observations can describe features caused by wind, water percolation, or snow unloading from trees. Water percolation into
13056-685: The mid 7th century AD as the invading forces conquered the Sassanian Empire , the region fell to Muslims after they fought the Kurds in Mosul and Tikrit 'Utba ibn Farqad captured all the forts of the Kurds when he conquered Erbil in 641. The area became part of the Muslim Arab Rashidun , Umayyad , and later the Abbasid Caliphates, before becoming part of various Iranian , Turkic , and Mongol emirates . Following
13184-463: The most conservative estimates. The large Kurdish town of Qala Dizeh (population 70,000) was completely destroyed by the Iraqi army. The campaign also included Arabization of Kirkuk, a program to drive Kurds and other ethnic groups out of the oil-rich city and replace them with Arab settlers from central and southern Iraq. Even though autonomy had been agreed in 1970, the local population did not enjoy any democratic freedom, facing similar conditions to
13312-454: The mountain West of the US or most of Iran and Afghanistan , very low flow for the rest of the year. In contrast, if much of the melt is from glaciated or nearly glaciated areas, the melt continues through the warm season, with peak flows occurring in mid to late summer. Glaciers form where the accumulation of snow and ice exceeds ablation. The area in which an alpine glacier forms is called
13440-409: The need for keeping roadways, wings, and windows clear; agriculture : providing water to crops and safeguarding livestock; sports such as skiing , snowboarding , and snowmachine travel; and warfare . Snow affects ecosystems , as well, by providing an insulating layer during winter under which plants and animals are able to survive the cold. Snow develops in clouds that themselves are part of
13568-420: The north to return government control of the region. Meanwhile, in June 1961, the KDP issued a detailed ultimatum to Qasim outlining Kurdish grievances, demanding that the Kurdish language would become an official language in Kurdish majority regions. Qasim ignored the Kurdish demands and continued his planning for war. It was not until September 10, when an Iraqi army column was ambushed by a group of Kurds, that
13696-581: The north-west Iranian group". Ludwig Paul concludes that Kurdish seems to be a Northwestern Iranian language in origin, but acknowledges that it shares many traits with Southwestern Iranian languages like Persian , apparently due to longstanding and intense historical contacts. Windfuhr identified Kurdish dialects as Parthian , albeit with a Median substratum. Windfuhr and Frye assume an eastern origin for Kurdish and consider it as related to eastern and central Iranian dialects. The present state of knowledge about Kurdish allows, at least roughly, drawing
13824-722: The opening ceremony, which was attended by Minister of Culture and other state officials. The channel uses the X , W , and Q letters during broadcasting. However, most of these restrictions on private Kurdish television channels were relaxed in September 2009. In 2010, Kurdish municipalities in the southeast began printing marriage certificates , water bills, construction and road signs , as well as emergency, social and cultural notices in Kurdish alongside Turkish. Also Imams began to deliver Friday sermons in Kurdish and Esnaf price tags in Kurdish. Many mayors were tried for issuing public documents in Kurdish language. The Kurdish alphabet
13952-598: The other languages spoken by Kurds in the region including the Gorani language in parts of Iranian Kurdistan and Iraqi Kurdistan. Philip G. Kreyenbroek , an expert writing in 1992, says: Since 1932 most Kurds have used the Roman script to write Kurmanji.... Sorani is normally written in an adapted form of the Arabic script.... Reasons for describing Kurmanji and Sorani as 'dialects' of one language are their common origin and
14080-611: The potential to earn several million dollars a week. Direct United States mediation led the two parties to a formal ceasefire in what was termed the Washington Agreement in September 1998. It is also argued that the Oil-for-Food Programme from 1997 onward had an important effect on cessation of hostilities. Iraqi Kurds played an important role in the Iraq War . Kurdish parties joined forces against
14208-488: The pro-government forces and consolidated his position as leader of the Kurds. At this point, Barzani ordered his forces to occupy and expel government officials from all Kurdish territory. This was not received well in Baghdad, and the Third Kurdish Teachers Congress was cancelled and Qasim even denied that "Kurds" constituted an own nation. Qasim began to prepare for a military offensive against
14336-448: The rain falls in winter and spring, and is usually heavy. Summer and early autumn are virtually dry, and spring is fairly tepid. Iraqi Kurdistan sees snowfall occasionally in the winter, and frost is common. There is a seasonal lag in some places in summer, with temperatures peaking around August and September. The provinces of Duhok, Erbil and Sulaymanyah are rich in agricultural lands. Wheat and other cereals are grown there. Most of
14464-418: The rebellion ended after a few days. As a result, the Iraqi government extended its control over the northern region after 15 years and in order to secure its influence, started an Arabization program by moving Arabs to the vicinity of oil fields in northern Iraq, particularly those around Kirkuk, and other regions, which were populated by Turkmen , Kurds and Christians. The repressive measures carried out by
14592-411: The region is Lake Dukan . There are also several smaller lakes, such as Darbandikhan Lake and Duhok Lake. The western and southern parts of Iraqi Kurdistan are not as mountainous as the east. Instead, it is rolling hills and plains vegetated by sclerophyll scrubland. Due to its latitude and altitude, Iraqi Kurdistan is cooler and much wetter than the rest of Iraq. Most areas in the region fall within
14720-465: The region, reducing its oil and food supplies. Elections held in June 1992 produced an inconclusive outcome, with the assembly divided almost equally between the two main parties and their allies. During this period, the Kurds were subjected to a double embargo : one imposed by the United Nations on Iraq and one imposed by Saddam Hussein on their region. The severe economic hardships caused by
14848-484: The region, which is distinguished by its fertile lands, plentiful water, and picturesque nature. The Great Zab and the Little Zab flow east–west in the region. The Tigris river enters Iraqi Kurdistan from Turkish Kurdistan . The mountainous nature of Iraqi Kurdistan, the difference of temperatures in its various parts, and its numerous bodies of water make it a land of agriculture and tourism. The largest lake in
14976-471: The region. During the Iran–Iraq War , the Iraqi government again implemented anti-Kurdish policies and a de facto civil war broke out. Iraq was widely condemned by the international community, but was never seriously punished for oppressive measures, including the use of chemical weapons against the Kurds, which resulted in thousands of deaths . The Anfal campaign constituted a systematic genocide of
15104-418: The region. In return, the Kurds under KDP enabled Saddam to establish an oil smuggling route through territory controlled by the KDP, with the active involvement of senior Barzani family members. The taxation of this trade at the crossing point between Saddam's territory and Kurdish controlled territory and then into Turkey, along with associated service revenue, meant that whoever controlled Dohuk and Zakho had
15232-724: The rest of Iraq. Things began to change after the 1991 uprising against Saddam Hussein at the end of the Persian Gulf War. The United Nations Security Council Resolution 688 gave birth to a safe haven following international concern for the safety of Kurdish refugees. The U.S. and the Coalition established a No Fly Zone over a large part of northern Iraq (see Operation Provide Comfort ), however, it left out Sulaymaniyah, Kirkuk and other important Kurdish populated regions. Bloody clashes between Iraqi forces and Kurdish troops continued and, after an uneasy and shaky balance of power
15360-401: The same point roughly 30 minutes apart. In cases where there is a large amount of vertical growth and mixing, the squall may develop embedded cumulonimbus clouds resulting in lightning and thunder which is dubbed thundersnow . A warm front can produce snow for a period as warm, moist air overrides below-freezing air and creates precipitation at the boundary. Often, snow transitions to rain in
15488-407: The speakers of these three languages may once have been in closer contact. Kurdish varieties are divided into three or four groups, with varying degrees of mutual intelligibility. In historical evolution terms, Kurmanji is less modified than Sorani and Pehlewani in both phonetic and morphological structure. The Sorani group has been influenced by among other things its closer cultural proximity to
15616-586: The two official languages of Iraq and is in political documents simply referred to as "Kurdish". The Kurdish varieties belong to the Iranian branch of the Indo-European family . They are generally classified as Northwestern Iranian languages, or by some scholars as intermediate between Northwestern and Southwestern Iranian. Martin van Bruinessen notes that "Kurdish has a strong South-Western Iranian element", whereas "Zaza and Gurani [...] do belong to
15744-406: The warm sector behind the front. Lake-effect snow is produced during cooler atmospheric conditions when a cold air mass moves across long expanses of warmer lake water, warming the lower layer of air which picks up water vapor from the lake, rises up through the colder air above, freezes, and is deposited on the leeward (downwind) shores. The same effect occurring over bodies of salt water
15872-551: The world. In the United States , a blizzard occurs when two conditions are met for a period of three hours or more: a sustained wind or frequent gusts to 35 miles per hour (16 m/s), and sufficient snow in the air to reduce visibility to less than 0.4 kilometers (0.25 mi). In Canada and the United Kingdom , the criteria are similar. While heavy snowfall often occurs during blizzard conditions, falling snow
16000-502: Was gradually converted to Christianity between 1st and 5th centuries and Erbil became the seat of the metropolitan of Hadhyab of the Church of the East and it was divided into several bishoprics namely Marga, Beth Garmai, Beth Qardu, Beth MahQard, Beth BihQard, Beth Nuhadra and Shahr-Qard. In Syriac the region was commonly called Beth Qardwaye. The region was conquered by Arab Muslims in
16128-443: Was greeted with a hero's welcome. As part of the deal arranged between Qasim and Barzani, Qasim had promised to give the Kurds regional autonomy in return for Barzani's support for his policies. The Provisional Constitution described Iraq being included in the Arab world but saw the Kurds as partners within an Iraqi statehood and the coat of arms included a Kurdish dagger besides the Arab sword. Meanwhile, during 1959–1960, Barzani became
16256-462: Was not able to subdue the insurrection. This stalemate irritated powerful factions within the military and is said to be one of the main reasons behind the Ba'athist coup against Qasim in February 1963. In November 1963, after considerable infighting amongst the civilian and military wings of the Ba'athists, they were ousted by Abdul Salam Arif in a coup. Then, after another failed offensive, Arif declared
16384-631: Was reached, the Iraqi government fully withdrew its military and other personnel from the region in October 1991 allowing Iraqi Kurdistan to function de facto independently. The region was to be ruled by the two principal Kurdish parties; the Kurdish Democratic Party (KDP) and the Patriotic Union of Kurdistan (PUK). The region also has its own flag and national anthem . At the same time, Iraq imposed an economic blockade over
