The Gelasian is an age in the international geologic timescale or a stage in chronostratigraphy , being the earliest or lowest subdivision of the Quaternary Period/System and Pleistocene Epoch/Series. It spans the time between 2.58 Ma (million years ago) and 1.80 Ma. It follows the Piacenzian Stage (part of the Pliocene ) and is followed by the Calabrian Stage.

105-701: The Gelasian was introduced in the geologic timescale in 1998. It is named after the Sicilian city of Gela in the south of the island. In 2009 it was moved from the Pliocene to the Pleistocene so that the geologic time scale would be more consistent with the key changes in Earth's climate, oceans, and biota that occurred 2.58 million years ago. The base of the Gelasian is defined magnetostratigraphically as

210-465: A dry summer climate , described by Köppen as Cs , is a temperate climate type that occurs in the lower mid-latitudes (normally 30 to 44 north and south latitude). Such climates typically have dry summers and wet winters, with summer conditions being hot and winter conditions typically being mild. These weather conditions are typically experienced in the majority of Mediterranean-climate regions and countries, but remain highly dependent on proximity to

315-424: A 40 mm (1.6 in) level. The third letter indicates the degree of summer heat: " a " represents an average temperature in the warmest month above 22 °C (72 °F), while " b " indicates the average temperature in the warmest month below 22 °C (72 °F). There is a "c" with 3 or less months' average temperature above 10 °C (50 °F), but this climate is rare and is very isolated. Under

420-891: A Csb climate because of its location inside the Alborz mountains . Winters in this zone are rainy and can be mild to chilly. Some locales in this zone experience some amount of snowfall, while others do not. Csb climates are found in northwestern Iberian Peninsula (namely Galicia and the Norte region and west coast of Portugal ), in coastal Northern California , in the Pacific Northwest (namely western Washington , western Oregon and southern portions of Vancouver Island in British Columbia ), in central Chile , in parts of southern Australia and in sections of southwestern South Africa . A few locations close to

525-456: A Mediterranean climate are near large bodies of water, temperatures are generally moderate, with a comparatively small range of temperatures between the winter low and summer high unlike (the relatively rare) dry-summer humid continental climates (although the daily diurnal range of temperature during the summer is large due to dry and clear conditions, except along the immediate coastlines). Temperatures during winter only occasionally fall below

630-613: A century of intensive agriculture. Much of the Overberg in the southern Cape of South Africa , was once covered with renosterveld , but has likewise been largely converted to agriculture, mainly for wheat . In hillside and mountainous areas, away from the urban sprawls , ecosystems and habitats of native vegetation are more sustained and undisturbed. The fynbos vegetation in the South-western Cape in South Africa

735-514: A cultural sense and the Greek language did not become extinct on the island, facilitating its re-hellenisation much later under the Byzantines. The once prosperous and contented island went into sharp decline when Verres became governor of Sicily (73 to 71 BC). In 70 BC noted figure Cicero condemned the misgovernment of Verres in his oration In Verrem . Various groups used the island as

840-668: A few kilometres inland. Occasionally also termed the "cool-summer Mediterranean climate", this subtype of the Mediterranean climate ( Csb ) is less common and experience warm (but not hot) and dry summers, with no average monthly temperatures above 22 °C (72 °F) during its warmest month and as usual an average in the coldest month between 18 and −3 °C (64 and 27 °F) or, in some applications, between 18 and 0 °C (64 and 32 °F). Also, at least four months must average above 10 °C (50 °F). Cool ocean currents, upwelling and higher latitudes are often

945-628: A geographical perspective, also forming a part of Sicily is the Maltese Archipelago, the islands home to the republic of Malta . The autonomous region also includes several neighbouring islands: the Aegadian Islands , the Aeolian Islands, Pantelleria and Lampedusa . The mountains of Sicily form a significant part of the island's diverse landscape, with Mount Etna , one of the world's most active volcanoes, being

1050-556: A mean temperature below 0 °C (32 °F) (or −3 °C [27 °F]), depending on the isotherm used). Regions in the Americas with this climate are influenced by the dry-summer trend (though briefly) that extends considerably poleward along the west coast, as well as the moderating influences of high altitude and relative proximity to the Pacific Ocean. These conditions maintain an unusually narrow temperature range through

1155-559: A power base at different times: slave insurgents occupied it during the First (135−132 BC) and Second (104−100 BC) Servile Wars . Sextus Pompey had his headquarters there during the Sicilian revolt of 44 to 36 BC. Christianity first appeared in Sicily during the years following AD 200; between this time and AD 313, when Emperor Constantine the Great lifted the prohibition on Christianity,

1260-532: A rich and unique culture in arts , music , literature , cuisine , and architecture . Its most prominent landmark is Mount Etna , the tallest active volcano in Europe, and one of the most active in the world, currently 3,357 m (11,014 ft) high. The island has a typical Mediterranean climate . It is separated from Calabria by the Strait of Messina . It is one of the five Italian autonomous regions and

1365-550: A season earlier than at the Dead Sea . In the Holy Land no rain at all falls in summer but early rains may come in autumn. The majority of the regions with Mediterranean climates have relatively mild winters and very warm summers. However, winter and summer temperatures can vary greatly between different regions with a Mediterranean climate. For instance, in the case of winters, Funchal experiences mild to warm temperatures in

1470-833: A significant number of Sicilians had become martyrs , including Agatha , Christina , Lucy , and Euplius . Christianity grew rapidly in Sicily over the next two centuries. Sicily remained a Roman province for around 700 years. The Western Roman Empire began falling apart after the invasion of Vandals , Alans, and Sueves across the Rhine on the last day of 406. Eventually the Vandals, after roaming about western and southern Hispania (present-day Iberia ) for 20 years, moved to North Africa in 429 and occupied Carthage in 439. The Franks moved south from present-day Belgium. The Visigoths moved west and eventually settled in Aquitaine in 418;

1575-405: A volcanic complex. The three volcanoes of Vulcano , Stromboli and Lipari are also active, although the last is usually dormant. Off the southern coast of Sicily, the underwater volcano of Ferdinandea , which is part of the larger Empedocles volcano , last erupted in 1831. It is located between the coast of Agrigento and the island of Pantelleria (which itself is a dormant volcano). From

1680-597: A yearly cycle in which abiotic (environmental) controls of stream populations and community structure dominate during floods, biotic components (e.g. competition and predation) controls become increasingly important as the flood discharge declines, and environmental controls regain dominance as environmental conditions become very harsh (i.e. hot and dry); as a result, these communities are well suited to recover from droughts , floods , and fires . Aquatic organisms in these regions show distinct long-term patterns in their structure and function, and are also highly sensitive to

1785-605: Is 25,711 km (9,927 sq mi), while the Autonomous Region of Sicily (which includes the smaller surrounding islands of Lipari , Egadi , Ustica , and Pantelleria ) has an area of 27,708 km (10,698 sq mi). The terrain of inland Sicily is mostly hilly and is intensively cultivated wherever possible. Along the northern coast, the mountain ranges of Madonie , 2,000 m (6,600 ft), Nebrodi , 1,800 m (5,900 ft), and Peloritani , 1,300 m (4,300 ft), are an extension of

1890-656: Is an island in the central Mediterranean Sea , south of the Italian Peninsula in continental Europe and is one of the 20 regions of Italy . With 4.8 million inhabitants, including 1.3 million in and around the capital city of Palermo , it is the most populous island in the Mediterranean Sea . It is named after the Sicels , who inhabited the eastern part of the island during the Iron Age . Sicily has

1995-424: Is closely associated with Mediterranean climate zones, as are unique freshwater communities, though vegetation native to the Mediterranean climate zone can also be found in the approximate nearby climate zones, which usually tend to be the humid subtropical , oceanic and/or semi-arid zones, depending on the region and location. Particularly distinctive of the climate are sclerophyll shrublands, called maquis in

2100-619: Is due to Sicily being geographically on the northern edge of the African Plate . Mount Etna is the largest active volcano in Europe and casts black ash over the island with its recurrent eruptions. It stands 3,403 metres (11,165 ft) high as of September 2024. It is the highest mountain in Italy south of the Alps . Etna covers an area of 1,190 km (459 sq mi) with a basal circumference of 140 km (87 mi). This makes it

2205-576: Is famed for its high floral diversity , and includes such plant types as members of the Restionaceae , Ericas (Heaths) and Proteas . Representatives of the Proteaceae also grow in Australia, such as Banksias . The palette of California native plants is also renowned for its species and cultivar diversity. This subtype of the Mediterranean climate ( Csa ) is the most common form of

2310-611: Is generally considered part of Southern Italy . The earliest archaeological record of human activity on the island is from around 14,000 BC. By around 750 BC, Sicily had three Phoenician and a dozen Greek colonies along its coasts, becoming one of the centers of Magna Graecia . The Sicilian Wars of 580–265 BC were fought between the Carthaginians and Greeks, and the Punic Wars of 264–146 BC were fought between Rome and Carthage. The Roman province of Sicilia ended with

2415-406: Is higher, steppe climates tend to prevail, but still follow the basic pattern of the Mediterranean climates. Irregularity of the rainfall, which can vary considerably from year to year, accentuates the droughts of the Mediterranean climate. Rain does not fall evenly, nor does the rain arrive at the same time or within the same intervals. In Gibraltar , for instance, rain starts falling nearly half

2520-543: Is seen as the beginning of the Quaternary ice age . Deep sea core samples have identified approximately 40 marine isotope stages (MIS 103 – MIS 64) during the age. Thus, there have probably been about 20 glacial cycles of varying intensity during the Gelasian. In the regional glacial history of the Alps , this age is now called Biber . It corresponds to Pre-Tegelen and Tegelen in Northern Europe. During

2625-816: Is the largest protected natural area of Sicily; it contains the largest forest in Sicily, the Caronia . The Hundred Horse Chestnut ( Castagno dei Cento Cavalli ), in Sant'Alfio , on the eastern slopes of Mount Etna, is the largest and oldest known chestnut tree in the world at 2,000–4,000 years old. Sicily has a wide variety of fauna. Species include the European wildcat , red fox , least weasel , pine marten , fallow deer , wild boar , crested porcupine , European hedgehog , common toad , Vipera aspis , golden eagle , peregrine falcon , Eurasian hoopoe and black-winged stilt . Roe deer were driven to extinction on

2730-665: The Alcantara flows through the province of Messina and enters the sea at Giardini Naxos , and the Simeto , which flows into the Ionian Sea south of Catania . Other important rivers on the island are the Belice and Platani in the southwest. Sicily has for the most part a typical Mediterranean climate ( Köppen climate classification : Csa ) with mild and wet winters and hot, dry summers with changeable intermediate seasons. On

2835-630: The Elymians and the Sicels . The most prominent and by far the earliest of these were the Sicani , who ( Thucydides writes) arrived from the Iberian Peninsula (perhaps Catalonia ). Some modern scholars, however, suggest classifying the Sicani as possibly an Illyrian tribe. Important historical evidence has been discovered in the form of cave drawings by the Sicani, dated from the end of

2940-531: The Emirate of Sicily began to fragment as intra-dynastic quarreling fractured the Muslim government. In 1038, seventy years after losing their last cities in Sicily, the Byzantines under the Greek general George Maniakes invaded the island together with their Varangian and Norman mercenaries. Maniakes was killed in a Byzantine civil war in 1043 before completing a reconquest and the Byzantines withdrew. Later

3045-819: The First Punic War (264 to 241 BC) and won, making Sicily–with the exception of Syracuse–the first Roman province outside of the Italian Peninsula by 242 BC. In the Second Punic War (218 to 201 BC), the Carthaginians attempted to recapture Sicily. Some of the Greek cities on the island who were loyal to Rome switched sides to help the Carthaginians, prompting a Roman military response. Archimedes , who lived in Syracuse, helped defend his city from Roman invasion; Roman troops killed him after they captured Syracuse in 213 BC. The Carthaginian attempt failed, and Rome became more unrelenting in its annihilation of

3150-580: The Kingdom of England . The court of Roger II became the most luminous centre of culture in the Mediterranean, both from Europe and the Middle East, like the multi-ethnic Caliphate of Córdoba , then only just eclipsed. This attracted scholars, scientists, poets, artists, and artisans of all kinds. Laws were issued in the language of the community to whom they were addressed in Norman Sicily, at

3255-603: The Köppen climate classification , "hot dry-summer" climates (classified as Csa ) and "cool dry-summer" climates (classified as Csb ) are often referred to as just "Mediterranean". Under the Köppen climate system, the first letter indicates the climate group (in this case temperate climates). Temperate climates or " C " zones average temperature above 0 °C (32 °F) (or −3 °C (27 °F)), but below 18 °C (64 °F), in their coolest months. The second letter indicates

3360-656: The Pleistocene epoch around 8000 BC. The Elymians , thought to have come from the area of the Aegean Sea , became the next tribe to join the Sicanians on Sicily. No evidence survives of warring between tribes, but the Sicanians moved eastwards when the Elymians settled in the northwest corner of the island. The Sicels are thought to have originated in Liguria ; they arrived from mainland Italy in 1200 BC and forced

3465-566: The Qanat to improve irrigation systems for agriculture. Around 1050, the western half of Sicily was ethnically and culturally distinct from central and eastern Sicily. During this time, there was also a small Jewish presence in Sicily, evidence seen in the catacombs discovered on the island. Palermo was initially ruled by the Aghlabids ; later it was the centre of the Emirate of Sicily, which

3570-406: The Strait of Messina , about 3 km (1.9 mi) wide in the north, and about 16 km (9.9 mi) wide in the southern part. The northern and southern coasts are each about 280 km (170 mi) long measured as a straight line, while the eastern coast measures around 180 km (110 mi); total coast length is estimated at 1,484 km (922 mi). The total area of the island

3675-738: The garrigue or maquis in the European Mediterranean Basin, the chaparral in California, the fynbos in South Africa , the mallee in Australia, and the matorral in Chile. Areas with this climate are also where the so-called "Mediterranean trinity" of major agricultural crops have traditionally been successfully grown ( wheat , grapes and olives ). As a result, these regions are notable for their high-quality wines, grapeseed/olive oils, and bread products. Under

3780-415: The subtropical ridge migrates towards the equator and leaves the area, making rainfall much more likely. As a result, areas with this climate receive almost all of their precipitation during their winter and spring seasons, and may go anywhere from four to six months during the summer and early fall without having any significant precipitation . In the lower latitudes, precipitation usually decreases in both

3885-623: The 455 sack of Rome, at Agrigento, but were defeated decisively by Ricimir in a naval victory off Corsica in 456. The island remained under Roman rule until 469. The Vandals lost possession of the island 8 years later in 477 to the East Germanic tribe of the Ostrogoths , who then controlled Italy and Dalmatia. The island was returned to the Ostrogoths by payment of tribute to their king Odoacer . He ruled Italy from 476 to 488 in

3990-604: The Andes in Northern Ecuador , Peru , Colombia , and Western Venezuela . The cold-summer subtype of the Mediterranean climate ( Csc ) is rare and predominantly found at scattered high-altitude locations along the west coasts of North and South America having a similar climate. This type is characterized by cool, dry summers, with less than four months with a mean temperature at or above 10 °C (50 °F), as well as with cool, wet winters, with no winter month having

4095-522: The Arabs failed to make permanent gains. They returned to Syria with their booty. Raids seeking loot continued until the mid-8th century. The Eastern Roman Emperor Constans II moved from Constantinople to Syracuse in 660. The following year he launched an assault from Sicily against the Lombard Duchy of Benevento , which occupied most of southern Italy. Rumors that the capital of the empire

4200-725: The Athenian army and their ships, selling most of the survivors into slavery . The Greek kingdom of Syracuse controlled most of eastern Sicily while Carthage controlled the western side. The two cultures began to clash, leading to the Greek-Punic wars (between 580 and 265 BC). The Greek states had begun to make peace with the Roman Republic in 262 BC, before the Romans sought to annex Sicily as their republic's first province . Rome attacked Carthage's holdings in Sicily in

4305-469: The Burgundians settled in present-day Savoy in 443. The Vandals found themselves in a position to threaten Sicily – only 100 miles away from their North African bases. After taking Carthage, the Vandals, personally led by King Gaiseric , laid siege to Palermo in 440 as the opening act in an attempt to wrest the island from Roman rule. The Vandals made another attempt to take the island one year after

Csb zones in the Köppen system include areas normally not associated with Mediterranean climates but with Oceanic climates, such as much of the Pacific Northwest , much of southern Chile , parts of west-central Argentina , and parts of New Zealand . Additional highland areas in

4725-671: The Mediterranean Basin, chaparral in California, matorral in Chile, fynbos in South Africa, and mallee and kwongan shrublands in Australia. Mediterranean vegetation shows a number of adaptations to drought , grazing , and frequent fire regimes. The small sclerophyllous leaves that characterize many of the perennial shrubs of this biome, help conserve water and prevent nutrient loss. The soils generally are of low fertility , and many plants have mutualistic relationships with nitrogen-fixing bacteria . Aquatic communities in Mediterranean climate regions are adapted to

4830-447: The Mediterranean climate typically experience hot, sometimes very hot and dry summers. Winters can be mild, cool or chilly, and some cities in this region receive somewhat regular snowfall (e.g. Kermanshah ), while others do not receive any (e.g. Casablanca ). Csa climates are mainly found around the Mediterranean Sea , southern Australia, southwestern South Africa , sections of Central Asia , northern sections of Iran and Iraq ,

Other minor Italic groups who settled in Sicily included the Ausones ( Aeolian Islands , Milazzo ) and the Morgetes of Morgantina . The Phoenician settlements in the western part of the island predate the arrival of Greek colonists. From about 750 BC, the Greeks began to live in Sicily ( Ancient Greek : Σικελία – Sikelia ), establishing many significant settlements. The most important colony

Marine Life of the Straits of Messina includes varieties of birds and marine life, including larger species such as greater flamingo and fin whale . The name Sicilia was given to the Roman province in 241 BC. It is named after the Sicels , who inhabited the eastern part of the island during the Iron Age . The ancient name of

5880-436: The capital under the Normans . The Normans formed a small but violent ruling class. They destroyed many of the Arab towns in Sicily, and very few physical remains survive from the Arab era. The Norman Hauteville family appreciated and admired the rich and layered culture in which they now found themselves. They also introduced into Sicily their own culture, customs, and politics from Normandy . Many Normans in Sicily adopted

In 826 Euphemius , the Byzantine commander in Sicily, having apparently killed his wife, forced a nun to marry him. Emperor Michael II caught wind of the matter and ordered general Constantine to end the marriage and cut off Euphemius' head. Euphemius rose up, killed Constantine, and then occupied Syracuse; he, in turn,

6090-406: The coasts, especially in the southwest, the climate is affected by the African currents and summers can be hot. Snow falls above 900 metres, but it can fall in the hills. The interior mountains, especially Nebrodi , Madonie , and Etna , enjoy a mountain climate, with heavy snowfalls during winter. The summit of Mount Etna is usually snow-capped from October to May. In the summer, the sirocco –

Similar to desert climates, in many Mediterranean climates there is a strong diurnal character to daily temperatures in the warm summer months due to strong solar heating during the day from sunlight and rapid cooling at night. In winter,

6300-414: The fall of the Roman Empire in the 5th century AD. Sicily was ruled during the Early Middle Ages by the Vandals , the Ostrogoths , the Byzantine Empire , and the Emirate of Sicily . The Norman conquest of southern Italy led to the creation of the County of Sicily in 1071, that was succeeded by Kingdom of Sicily , a state that existed from 1130 until 1816 under various dynasties, and in 1816 it

6405-557: The freezing point and snow is generally seldom seen. Summer temperatures can be cool to very hot, depending on the distance from a large body of water, elevation, and latitude, among other factors. Strong winds from inland desert regions can sometimes boost summer temperatures up, quickly increasing the risk of wildfires . Notable exceptions to the usual proximity from bodies of water, thus featuring extremely high summer temperatures and cooler winters, include south-eastern Turkey and northern Iraq ( Urfa , Erbil ), surrounded by hot deserts to

Southern California's coasts also experience hot summers due to the shielding effect of the Channel Islands . However, unshielded areas of that coastline can have warm-summer Mediterranean climates with hot-summer areas just

6930-425: The invaders; Roman consul M. Valerian told the Roman Senate in 210 BC that "no Carthaginian remains in Sicily". As the Roman Republic's granary , Sicily ranked as an important province, divided into two quaestorships : Syracuse to the east and Lilybaeum to the west. Roman rule introduced the Latin language to the island, which underwent a slow process of latinisation but Sicily remained largely Greek in

7035-411: The island (dating to the second half of the third millennium BC) seem to offer new insights into the culture of primitive Sicily. The impact of at least two influences is clear: the European one coming from the Northwest, and the Mediterranean influence of an eastern heritage. The original classical-era inhabitants of Sicily comprised three defined groups of the ancient peoples of Italy : the Sicani ,

7140-433: The island is Trinacria (Greek Τρινακρία "having three headlands") for its triangular shape, likely a re-interpretation of earlier ( Homeric ) Thrinacia . The Greek name was rendered as Trīnācrĭa in classical Latin ( Virgil , Ovid ). Humans first colonized Sicily towards the end of the Late Pleistocene , around 16,000 years ago, by people associated with the Epigravettian culture. Discoveries of dolmens on

7245-491: The island was turned into an agricultural region. This gradually dried the climate, leading to a decline in rainfall and the drying of rivers. The central and southwest provinces are practically devoid of forest. In Northern Sicily, there are three important forests; near Mount Etna, in the Nebrodi Mountains and in the Bosco della Ficuzza Natural Reserve near Palermo . The Nebrodi Mountains Regional Park, established on 4 August 1993 and covering 86,000 hectares (210,000 acres),

During the Late Pleistocene , a species of dwarf elephant , Palaeoloxodon mnaidriensis inhabited the island, with its latest records on Sicily dating to around 20,000 years ago. The Riserva naturale dello Zingaro (Zingaro Natural Reserve) is one of

7455-407: The island. Linguistically, the island shifted from being one-third Greek- and two-thirds Arabic-speaking at the time of the Norman conquest to becoming fully Latinised . In terms of religion the island became completely Roman Catholic (bearing in mind that until 1054 the Churches owing allegiance to the Pope and the Patriarch of Constantinople belonged to one Church); Sicily before the Norman conquest

7560-524: The largest city, Syracuse, held out until 878 and the Greek city of Taormina fell in 962. It was not until 965 that all of Sicily was conquered by the Arabs . In the 11th-century Byzantine armies carried out a partial reconquest of the island under George Maniakes , but it was their Norman mercenaries who would eventually complete the island's reconquest at the end of the century. The Arabs initiated land reforms , which increased productivity and encouraged

7665-473: The largest of the three active volcanoes in Italy , being about two and a half times the height of the next largest, Mount Vesuvius . In Greek mythology , the deadly monster Typhon was trapped under the mountain by Zeus , the god of the sky. Mount Etna is widely regarded as a cultural symbol and icon of Sicily. The Aeolian Islands in the Tyrrhenian Sea , to the northeast of mainland Sicily form

7770-432: The lowland areas, temperatures which can sometimes prohibit the growth of typical cold-sensitive Mediterranean plants. Some Spanish authors opt to use the term 'continental Mediterranean climate' ( Clima Mediterráneo Continentalizado ) for some regions with lower temperatures in winter than the coastal areas, but Köppen's Cs zones show no distinction as long as winter temperature means stay above freezing. Additionally,

7875-462: The mainland Apennines . The cone of Mount Etna dominates the eastern coast. In the southeast lie the lower Hyblaean Mountains , 1,000 m (3,300 ft). The mines of the Enna and Caltanissetta districts were part of a leading sulphur -producing area throughout the 19th century, but have declined since the 1950s. Sicily and its surrounding small islands have some highly active volcanoes. This

7980-637: The name of the Byzantine (Eastern Roman) Emperor. The Vandals kept a toehold in Lilybaeum , a port on the west coast. They lost this in 491 after making one last attempt to conquer the island from this port. The Ostrogothic conquest of Sicily (and of Italy as a whole) under Theodoric the Great began in 488. The Byzantine Emperor Zeno had appointed Theodoric as a military commander in Italy. The Goths were Germanic, but Theodoric fostered Roman culture and government and allowed freedom of religion. In 461 from

8085-512: The new Ostrogoth king Totila counterattacked, moving down the Italian peninsula, plundering and conquering Sicily in 550. Totila was defeated and killed in the Battle of Taginae by Byzantine general Narses in 552 but Italy was in ruins. At the time of the reconquest Greek was still the predominant language spoken on the island. Sicily was invaded by the Arab forces of Caliph Uthman in 652, but

8190-496: The ocean, altitude and geographical location. The dry summer climate is found throughout the warmer middle latitudes , affecting almost exclusively the western portions of continents in relative proximity to the coast. The climate type's name is in reference to the coastal regions of the Mediterranean Sea , which mostly share this type of climate, but it can also be found in the Atlantic portions of Iberia and Northwest Africa,

8295-580: The precipitation pattern (" s " represents dry summers). Köppen has defined a dry summer month as a month with less than 30 mm (1.2 in) of precipitation and as a month within the high-sun months of April to September, in the case of the Northern Hemisphere and October to March, in the case of the Southern Hemisphere, and it also must contain exactly or less than one-third that of the wettest winter month. Some, however, use

8400-530: The reason for this cooler type of Mediterranean climate. The other main reason for this cooler type is the altitude . For instance, Menton on the French coast has a Csa climate while Castellar, Alpes-Maritimes , the adjacent town just north of Menton, with an altitude between 100 and 1,382 m (328 and 4,534 ft), has a Csb climate instead. The village of Siah Bisheh in Northern Iran also has

8505-650: The recent effects of climate change . The native vegetation of Mediterranean climate lands must be adapted to survive long, hot summer droughts in summer and prolonged wet periods in winter. Mediterranean vegetation examples include the following: Many native vegetations in Mediterranean climate area valleys have been cleared for agriculture and farming. In places such as the Sacramento Valley and Oxnard Plain in California , draining marshes and estuaries combined with supplemental irrigation has led to

8610-738: The settlers built many temples throughout Sicily, including several in the Valley of the Temples at Agrigento . Politics on the island became intertwined with those of Greece; Syracuse became desired by the Athenians who set out on the Sicilian Expedition (415–413 BC) during the Peloponnesian War . Syracuse gained Sparta and Corinth as allies and, as a result, defeated the Athenian expedition. The victors destroyed

8715-419: The south and mountains to the north. Those places routinely experience summer daily means of over 30 °C (86 °F) and daily highs above 40 °C (104 °F), while receiving enough rainfall in winter not to fall into arid or semi-arid classifications. As in every climatologic domain, the highland locations of the Mediterranean domain can present cooler temperatures in the summer and winter than

8820-546: The south coast of England such as Weymouth and Portland just scrape into this climate classification due to very low rainfall in July. A trend towards slightly drier summers during the 1971–2000 climate average period, meant that this classification previously extended slightly further to include a few other weather stations in southern England, such as Bognor Regis and Teignmouth . Rarer instances of this climate can be found in relatively small and isolated high altitude areas of

8925-622: The status of the island to a kingdom in 1130, along with his other holdings, which included the Maltese Islands and the Duchies of Apulia and Calabria . Roger II appointed the powerful Greek George of Antioch to be his "emir of emirs" and continued the syncretism of his father. During this period, the Kingdom of Sicily was prosperous and politically powerful, becoming one of the wealthiest states in all of Europe—even wealthier than

9030-743: The subtropics also meet Cs requirements, though they, too, are not normally associated with Mediterranean climates. The same goes for a number of oceanic islands such as Madeira , the Juan Fernández Islands , the western part of the Canary Islands , and the eastern part of the Azores . Under Trewartha 's modified Köppen climate classification, the two major requirements for a Cs climate are revised. Under Trewartha's system, at least eight months must have average temperatures of 10 °C (50 °F) or higher ( subtropical ), and

9135-537: The sun. Poleward extension and expansion of the subtropical anticyclone over the oceans bring subsiding air to the region in summer, with clear skies and high temperatures. When the anticyclone moves Equator-ward in winter, it is replaced by traveling, frontal cyclones with their attendant precipitation. During summer, regions of the Mediterranean climate are strongly influenced by the subtropical ridge which keeps atmospheric conditions very dry with minimal cloud coverage. In some areas, such as coastal California ,

9240-461: The temperature and rainfall pattern for a Csa or even a Csb climate can exist as a microclimate in some high-altitude locations adjacent to a rare tropical As ( tropical savanna climate with dry summers, typically in a rainshadow region, as in Hawaii). These have a favourable climate, with mild wet winters and fairly warm, dry summers. The Mediterranean forests, woodlands, and scrub biome

9345-420: The time when the culture was still heavily Arab and Greek. Governance was by rule of law which promoted justice. Muslims, Jews, Byzantine Greeks , Lombards, and Normans worked together fairly amicably. During this time many extraordinary buildings were constructed. However this situation changed as the Normans imported immigrants from Normandy , England , Lombardy, Piedmont, Provence and Campania to secure

9450-702: The tropics, on Haleakalā Summit in Hawaii. In South America, Csc regions can be found along the Andes in Chile and Argentina. The town of Balmaceda, Chile is one of the few towns confirmed to have this climate. Small areas with a Csc climate can be found at high elevations in Corsica . In Norway, the small fishing village of Røstlandet , in Røst Municipality , above the Arctic Circle has

9555-493: The west; Val Demone in the northeast; and Val di Noto in the southeast. As dhimmis , that is as members of a protected class of approved monotheists, the Eastern Orthodox Christians were allowed freedom of religion , but had to pay a tax, the jizya (in lieu of the obligatory alms tax, the zakat , paid by Muslims), and were restricted from active participation in public affairs. By the 11th century,

9660-452: The western coasts of landmasses, between roughly 30 and 45 degrees north or south of the equator . The main cause of Mediterranean, or dry summer, climate is the subtropical ridge , which extends towards the pole of the hemisphere in question during the summer and migrates towards the equator during the winter. This is due to the seasonal poleward-equatorward variations of temperatures. The resulting vegetation of Mediterranean climates are

9765-531: The wind from the Sahara – can be felt. Rainfall is scarce, and in some provinces a water crisis can occur. According to the Regional Agency for Waste and Water, on 10 August 1999, the weather station of Catenanuova (EN) recorded an unofficial maximum temperature of 48.5 °C (119 °F). On 11 August 2021, a new highest temperature record for Europe with a reading of 48.8 °C (119.8 °F)

9870-541: The winter and summer due to higher evapotranspiration . Toward the polar latitudes, total moisture usually increases; for instance, the Mediterranean climate in Southern Europe has more rain. The rainfall also tends to be more evenly distributed throughout the year in Southern Europe, while in places such as Southern California , the summer is nearly or completely dry. In places where evapotranspiration

9975-410: The winter, with frost and snowfall almost unknown, whereas Tashkent has cold winters with annual frosts and snowfall; or, to consider summer, Seville experiences rather high temperatures in that season. In contrast, San Francisco has cool summers with daily highs around 21 °C (70 °F) due to the continuous upwelling of cold subsurface waters along the coast. Because most regions with

10080-554: The year for climate zones at such distances from coasts. In North America, areas with Csc climate can be found in the Olympic , Cascade , Klamath , and Sierra Nevada ranges in Washington, Oregon and California. These locations are found at high altitude nearby lower altitude regions characterized by a warm-summer Mediterranean climate ( Csb ) or hot-summer Mediterranean climate ( Csa ). A rare instance of this climate occurs in

10185-657: Was Sicily, leading to the Gothic War (535–554) between the Ostrogoths and the Eastern Roman Empire, also known as the Byzantine Empire . Justinian's general Belisarius was assigned to the military task. Sicily was used as a base for the Byzantines to conquer the rest of Italy, including Naples , Rome, and Milan . It took five years before the Ostrogoth capital Ravenna fell in 540. However,

10290-506: Was defeated and driven out to North Africa. He offered the rule of Sicily to Ziyadat Allah , the Aghlabid Emir of Tunisia , in return for a position as a general and a place of safety. A Muslim army was then sent to the island consisting of Arabs , Berbers , Cretans , and Persians . The Muslim conquest of Sicily was a see-saw affair and met with fierce resistance. It took over a century for Byzantine Sicily to be conquered;

10395-667: Was given by Ibn Hawqal , an Arab merchant who visited Sicily in 950. A walled suburb, called the Al-Kasr (the palace), is the centre of Palermo to this day, with the great Friday mosque on the site of the later Roman cathedral. The suburb of al-Khalisa (modern Kalsa ) contained the Sultan 's palace, baths, a mosque, government offices, and a private prison. Ibn Hawqal estimated there were 7,000 butchers trading in 150 shops. The Muslim rule introduced lemons, oranges and sugar cane, as well as cotton and mulberries for sericulture, and introduced

10500-687: Was in Syracuse ; others grew up at Akragas , Selinunte , Gela , Himera and Zancle . The native Sicani and Sicel peoples became absorbed into the Hellenic culture with relative ease, and the area became part of Magna Graecia along with the coasts of the south of the Italian peninsula , which the Greeks had also colonised. Sicily had fertile soils, and the successful introduction of olives and grape vines fostered profitable trading. Greek culture significantly centered around Greek religion , and

10605-417: Was set near the city of Syracuse . Total precipitation is highly variable, generally increasing with elevation. In general, the southern and southeast coast receives the least rainfall (less than 50 cm (20 in)), and the northern and northeastern highlands the most (over 100 cm (39 in)). Sicily is an often-quoted example of man-made deforestation , which has occurred since Roman times when

10710-459: Was to be moved to Syracuse probably cost Constans his life, as he was assassinated in 668. His son Constantine IV succeeded him. A brief usurpation in Sicily by Mezezius was quickly suppressed by this emperor. Contemporary accounts report that the Greek language was widely spoken on the island during this period. In 740 Emperor Leo III the Isaurian transferred Sicily from the jurisdiction of

10815-782: Was under the Eastern Orthodox Patriarch. After Pope Innocent III made him Papal Legate in 1098, Roger I created several Catholic bishoprics while still allowing the construction of 12 Greek-speaking monasteries (the Greek language, monasteries, and 1500 parishes continued to exist until the adherents of the Greek Rite were forced in 1585 to convert to Catholicism or leave; a small pocket of Greek-speakers still live in Messina). Mediterranean climate A Mediterranean climate ( / ˌ m ɛ d ɪ t ə ˈ r eɪ n i ən / MED -ih-tə- RAY -nee-ən ), also called

10920-563: Was under the nominal suzerainty of the Fatimid Caliphate . During the reign of this dynasty revolts by Byzantine Sicilians continuously occurred especially in the east where Greek-speaking Christians predominated. Parts of the island were re-occupied before revolts were quashed. Under the Arab rule the island was divided in three administrative regions , or "vals", roughly corresponding to the three "points" of Sicily: Val di Mazara in

11025-488: Was unified with the Kingdom of Naples into the Kingdom of the Two Sicilies . From the 1282 Sicilian Vespers until the 1860 Expedition of the Thousand , Sicily was ruled by Aragon and then Spain , either in personal union with the crown or by a cadet branch , with the exception of a period of Savoy and then Habsburg rule in 1713–1735. The island became part of the newly unified Italy in 1860 following
