A Mediterranean climate ( / ˌ m ɛ d ɪ t ə ˈ r eɪ n i ən / MED -ih-tə- RAY -nee-ən ), also called 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 the ocean, altitude and geographical location.
99-593: 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, the Pacific portions of

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
297-884: 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

1089-555: 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

Notwithstanding the fact that hydrangeas were introduced from America or Asia, some locals consider them a symbol of the archipelago and propagate them along roadsides. Cryptomeria , the Japanese cedar, is a conifer extensively grown for its timber. The two most common of these alien species are Pittosporum undulatum and Hedychium gardnerianum . Reforestation efforts with native laurissilva vegetation have been accomplished successfully in many parts of

The archipelago of the Azores is located in the middle of the northern hemisphere of the Atlantic Ocean and extends along a west-northwest to east-southeast orientation (between 36.5°–40° North latitudes and 24.5°–31.5° West longitudes ) in an area approximately 600 km (373 mi) wide. The islands of the Azores emerged from what
1782-595: 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

There were no large animals on Santa Maria; after its discovery and before settlement began, sheep were let loose on the island to supply future settlers with food. The archipelago was largely settled from mainland Portugal, but settlement did not take place right away. Gonçalo Velho Cabral gathered resources and settlers for

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
3465-512: 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 the garrigue or maquis in the European Mediterranean Basin,
3564-415: 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

There are nine major Azorean islands and an islet cluster, in three main groups. These are Flores and Corvo , to the west; Graciosa , Terceira , São Jorge , Pico , and Faial in the centre; and São Miguel , Santa Maria , and the Formigas islets to the east. They extend for more than 600 km (370 mi) and lie in

A great part of it has been wiped out in the past 600 years for its valuable wood (for tools, buildings, boats, fire wood, and so on) and to clear land for agriculture. As a result, it is estimated that more than half of insects on the Graciosa island have disappeared or will become extinct. Many cultivated places (which are traditionally dedicated to pasture or to growing taro , potatoes, maize and other crops) have now been abandoned, especially as

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 the subtropics also meet Cs requirements, though they, too, are not normally associated with Mediterranean climates. The same goes for
4554-669: 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

Responding to the consequent economic problems, some people of the Azores began to emigrate to the United States, Canada and Brazil. In 1902, the Dominion Line began operating a Mediterranean passenger service between Boston and Italy via Gibraltar and
5049-732: The Portuguese ruler António de Oliveira Salazar leased air and naval bases in the Azores to Great Britain. The occupation of these facilities in October 1943 was codenamed Operation Alacrity by the British. This was a key turning point in the Battle of the Atlantic , enabling the Royal Air Force , the U.S. Army Air Forces , and the U.S. Navy to provide aerial coverage in the Mid-Atlantic gap . This helped them to protect convoys and to hunt hostile German U-boats . In 1944,

Ponta Delgada received its city status in 1546. From the first settlement, the pioneers applied themselves to agriculture, and by the 15th century Graciosa was exporting wheat, barley, wine and brandy. The goods were sent to Terceira largely because of
5643-434: The cold current has a stabilizing effect on the surrounding air, further reducing the chances for rain, but often causing thick layers of marine fog that usually evaporates by mid-day. 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,

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

7227-716: The other islands (including specifically on São Miguel, where the Gonçalvez da Câmara family supported the Spanish claimant). An English raid of the Azores in 1589 successfully plundered some islands and harbouring ships; eight years later, a second raid failed – the Islands Voyage . Spain held the Azores under the Iberian Union from 1580 to 1642 (called the "Babylonian captivity" in the Azores). The Azores were
7326-580: 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
7425-534: The proximity of that island. Portugal fell into a dynastic crisis following the death of Cardinal-King Henry of Portugal in 1580. Of the various claimants to the crown, the most powerful was king Phillip II of Spain , who justified his rights to the Portuguese throne by the fact that his mother was a Portuguese royal princess, his maternal grandfather having been King Manuel I of Portugal. Following his proclamation in Santarém, António, Prior of Crato
7524-528: 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
7623-647: 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
7722-483: The region has been a center of intense seismic activity, particularly along its tectonic boundaries on the Mid-Atlantic Ridge and Terceira Rift. Seismic events although frequent, are usually tectonic or vulco-tectonic in nature, but in general are of low to medium intensities, occasionally punctuated by events of level 5 or greater on the Richter scale . The most severe earthquake was registered in 1757, near Calheta on
7821-594: The revolution, hoping to establish an independent Azores, until operations ceased in 1975. In 1976, the Azores became the Autonomous Region of the Azores ( Região Autónoma dos Açores ), one of the autonomous regions of Portugal , and the subdistricts of the Azores were eliminated. In 2003, the Azores saw international attention when United States President George W. Bush , British Prime Minister Tony Blair , Spanish Prime Minister José María Aznar , and Portuguese Prime Minister José Manuel Durão Barroso held
7920-605: The seamounts and submarine volcanoes off the coast of Serreta and in the Pico-São Jorge Channel. The islands have many examples of volcano-built geomorphology including caves and lava tubes (such as the Gruta das Torres , Algar do Carvão , Gruta do Natal , Gruta das Cinco Ribeiras), the coastal lava fields (like the coast of Feteiras , Faial, the Mistério of Prainha or São João on Pico Island) in addition to
8019-461: The service to both New York and Boston throughout their careers. By the time the service ended in 1921, these four ships had transported an estimated total of 58,000 Azorean Portuguese to the United States. The Portuguese Civil War (1828–1834) had strong repercussions in the Azores. In 1829, in Praia da Vitória , the liberals won over the absolutists , making Terceira Island the main headquarters of
8118-549: The smallest, Corvo, at approximately 17 km (7 sq mi). Each of the islands has its own distinct geomorphological characteristics that make them unique: These islands can be divided into three recognizable groups located on the Azores Plateau: São Jorge, Pico and Faial are also collectively called Ilhas do Triângulo ('Islands of the Triangle'). Several sub-surface reefs (particularly
8217-418: 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
8316-545: 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
8415-572: The southwest; it is an extensive form crossed by many transform faults running perpendicular to its north–south orientation, that is seismically active and susceptible to volcanism. The Azores features a series of prominent peaks, with Montanha do Pico (also known as "Mount Pico") standing as the highest at 2,351 meters on Pico Island . Other notable elevations include Pico da Vara on São Miguel Island , Pico da Esperança on São Jorge Island , Cabeço Gordo on Faial Island , and Calderia de Santa Barbara on Terceira Island . The Terceira Rift
8514-536: 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 ,
8613-697: The tallest mountains on the planet. The Azores are located at the seismically active Azores triple junction plate boundary where the North American plate , Eurasian plate and Nubian plate meet. The climate of the Azores is very mild for such a northerly location, being influenced by its distance from the continents and by the passing Gulf Stream . Because of the marine influence, temperatures remain mild year-round. Daytime temperatures normally fluctuate between 16 and 25 °C (61 and 77 °F) depending on season. Temperatures above 30 °C (86 °F) or below 3 °C (37 °F) are unknown in
8712-461: 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
8811-426: The time belonging to Burgundy. There was a revolt against Philip's rule, and disease and hunger became rampant. Isabel appealed to Henry to allow some of the unruly Flemings to settle in the Azores. He granted this and supplied them with means of transport and goods. In 1522, Vila Franca do Campo , then the capital of São Miguel , was devastated by an earthquake and landslide that killed about 5,000 people, and
8910-637: 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
9009-481: The unoccupied islands started in 1439 with people mainly from the continental provinces of Algarve and Alentejo , in mainland Portugal. São Miguel was first settled in 1449, the settlers – mainly from the Estremadura , Alto Alentejo and Algarve areas of mainland Portugal – under the command of Gonçalo Velho Cabral, who landed at the site of modern-day Povoação . The first reference to the island of São Jorge
9108-484: The volcanic activity has centered, primarily, along the Terceira Rift. From the beginning of the islands' settlement, around the 15th century, there have been 28 registered volcanic eruptions (15 terrestrial and 13 submarine). The last significant volcanic eruption, the Capelinhos volcano ( Vulcão dos Capelinhos ), occurred off the coast of the island of Faial in 1957; the most recent volcanic activity occurred in
9207-535: The winds on the northern hemisphere are not as strong as in the southern hemisphere, due to the large landmasses of North America, Europe and Asia. There are six types of mid-latitude climates consisting of: mediterranean , desert , humid subtropical , oceanic , humid continental and subarctic . Azores The Azores ( / ə ˈ z ɔːr z / ə- ZORZ , US also / ˈ eɪ z ɔːr z / , AY -zorz ; Portuguese : Açores , Portuguese pronunciation: [ɐˈsoɾɯ̞ʃ] ), officially
9306-541: 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
9405-406: 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
9504-508: The world's major tectonic plates (the North American plate , the Eurasian plate and the African plate ), a condition that has translated into the existence of many faults and fractures in this region of the Atlantic. The westernmost islands of the archipelago (Corvo and Flores) are located on the North American plate, while the remaining islands are located within the boundary that divides
9603-554: 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
9702-543: Was acclaimed in the Azores in 1580 (through his envoy António da Costa) but was expelled from the continent by the Spaniards following the Battle of Alcântara . Yet, through the administration of Cipriano de Figueiredo, governor of Terceira (who continued to govern Terceira in the name of ill-fated, former King Sebastian of Portugal ), the Azoreans resisted Spanish attempts to conquer the islands (including specifically at
9801-407: Was made in 1439, but the date of discovery is unknown. In 1443, the island was already inhabited, but settlement began only after the arrival of the noble Flemish native Willem van der Haegen . Arriving at Topo , São Jorge, where he lived and died, he became known as Guilherme da Silveira to the islanders. João Vaz Corte-Real received the captaincy of the island in 1483. Velas became a town before
