==Notably affected regions== There are regular patterns of [[prevailing winds]] found in bands round Earth's [[equator]]ial region. The zone designated the [[trade winds]] is the zone between about 30° N and 30° S, blowing predominantly from the northeast in the [[Northern Hemisphere]] and from the southeast in the [[Southern Hemisphere]].<ref>{{cite web |author=Glossary of Meteorology |title=trade winds |work=Glossary of Meteorology |publisher=American Meteorological Society |year=2009 |access-date=4 July 2021 |url=https://glossary.ametsoc.org/wiki/Trade_winds}}</ref> The [[westerlies]] are the prevailing winds in the [[middle latitudes]] between 30 and 60 degrees [[latitude]], blowing predominantly from the southwest in the Northern Hemisphere and from the northwest in the Southern Hemisphere.<ref>{{cite web |author=Glossary of Meteorology |title=westerlies |work=Glossary of Meteorology |publisher=American Meteorological Society |year=2009 |access-date=4 July 2021 |url=https://glossary.ametsoc.org/wiki/Westerlies}}</ref> Some of the strongest westerly winds in the middle latitudes can come in the [[Roaring Forties]] of the Southern Hemisphere, between 30 and 50 degrees latitude.<ref>{{cite web |author=Glossary of Meteorology |title=roaring forties |work=Glossary of Meteorology |publisher=American Meteorological Society |year=2009 |access-date=4 July 2021 |url=https://glossary.ametsoc.org/wiki/Roaring_forties}}</ref> Examples of notable rain shadowing include: ===Africa=== ====Northern Africa==== [[File:Algeria.A2002118.1040.250m.jpg|thumb|right|230px|The [[Atlas Mountains]]' (top) rain shadow effect makes the [[Sahara]] even drier.]] * The [[Sahara]] is made even drier because of a strong rain shadow effects caused by major mountain ranges (whose highest points can culminate up to more than 4,000 meters; 2½ miles high). To the northwest, the [[Atlas Mountains]], covering the [[Mediterranean]] coast for [[Morocco]], [[Algeria]] and [[Tunisia]]. On the [[windward]] side of the [[Atlas Mountains]], the warm, moist winds blowing from the northwest off the [[Atlantic Ocean]], which contain a lot of water vapor, are forced to rise, lift up and expand over the mountain range. This causes them to cool down, which causes an excess of moisture to condense into high clouds and results in heavy precipitation over the mountain range. This is known as [[orographic rainfall]] and after this process, the air is dry because it has lost most of its moisture over the [[Atlas Mountains]]. On the [[leeward]] side, the cold, dry air starts to descend and to sink and compress, making the winds warm up. This warming causes the moisture to evaporate, making clouds disappear. This prevents rainfall formation and creates desert conditions in the Sahara. * Desert regions in the [[Horn of Africa]] ([[Ethiopia]], [[Eritrea]], [[Somalia]] and [[Djibouti]]) such as the [[Danakil Desert]] are all influenced by the air heating and drying produced by rain shadow effect of the [[Ethiopian Highlands]]. ====Southern Africa==== [[File:A virtually cloudless image of Madagascar ESA230211.jpg|thumb|230px|The mountain ranges on the eastern side of [[Madagascar]] provide a rain shadow for the country's western portion.]] * The windward side of the island of [[Madagascar]], which sees easterly on-shore winds, is wet tropical, while the western and southern sides of the island lie in the rain shadow of the central highlands and are home to thorn forests and deserts. The same is true for the island of [[Réunion]].{{citation needed|date=July 2023}} * On [[Tristan da Cunha]], [[Sandy Point, Tristan da Cunha|Sandy Point]] on the east coast is warmer and drier than the rainy, windswept settlement of [[Edinburgh of the Seven Seas]] in the west.{{citation needed|date=July 2023}} * In [[Western Cape Province]], the [[Breede River Valley]] and the [[Karoo]] region lie in the rain shadow of the [[Cape Fold Mountains]] and are arid; whereas the wettest parts of the Cape Mountains can receive {{convert|1500|mm|in|0}}, [[Worcester, South Africa|Worcester]] receives only around {{convert|200|mm|in|0}} and is useful only for grazing.{{citation needed|date=July 2023}} ===Asia=== ====Central and Northern Asia==== * The [[Himalayas]] and connecting ranges also contribute to arid conditions in [[Central Asia]] including [[Mongolia]]'s [[Gobi]] desert, as well as the [[Semi-arid climate|semi-arid]] steppes of Mongolia and north-central to north western China.{{citation needed|date=July 2023}} * The [[Verkhoyansk Range]] in eastern [[Siberia]] is the coldest place in the [[Northern Hemisphere]], because the moist southeasterly winds from the [[Pacific Ocean]] lose their moisture over the coastal mountains well before reaching the [[Lena River]] valley, due to the intense [[Siberian High]] forming around the very cold continental air during the winter. One effect in the [[Sakha Republic]] (Yakutia) is that, in [[Yakutsk]], [[Verkhoyansk]], and [[Oymyakon]], the average temperature in the coldest month is below {{convert|-38|°C}}. These regions are synonymous with extreme cold.{{citation needed|date=July 2023}} ====Eastern Asia==== * The [[Ordos Desert]] is rain shadowed by mountain chains including the Kara-naryn-ula, the Sheitenula, and the [[Yin Mountains]], which link on to the south end of the [[Great Khingan Mountains]]. * The central region of [[Myanmar]] is in the rain shadow of the [[Arakan Mountains]] and is almost semi-arid with only {{convert|750|mm|in|0}} of rain, versus up to {{convert|5.5|m|in|-1}} on the [[Rakhine State]] coast. * The plains around Tokyo, Japan – known as [[Kantō Plain|Kanto plain]] – during winter experiences significantly less precipitation than the rest of the country by virtue of surrounding mountain ranges, including the [[Japanese Alps]], blocking prevailing northwesterly winds originating in Siberia. ====Southern Asia==== [[File:Ghat satellite view.jpg|thumb|230px|The eastern regions of the [[Western Ghats]] lie in a rain shadow, receiving far less rainfall.]] * The eastern side of the [[Sahyadri]] ranges on the [[Deccan Plateau]] including: [[Vidarbha]], [[North Karnataka]], [[Rayalaseema]] and western [[Tamil Nadu]].{{citation needed|date=July 2023}} * [[Gilgit]] and [[Chitral]], Pakistan, are rainshadow areas. * The [[Thar Desert]] is bounded and rain shadowed by the [[Aravalli Range|Aravalli]] ranges to the southeast, the Himalaya to the northeast, and the Kirthar and Sulaiman ranges to the west.{{citation needed|date=July 2023}} *The [[Central Highlands of Sri Lanka]] rain shadow the northeastern parts of the island, which experience much less severe [[Monsoon of South Asia|summer monsoon]] rains and instead have precipitation peaks in autumn and winter. ====Western Asia==== [[File:Envisat image of the southern Caspian Sea ESA223952.tiff|thumb|230px|Most of Iran is rain-shadowed by the [[Alborz]] mountains in the north (just south of the [[Caspian Sea]]), hence the country's mostly (semi) arid climate.]] [[File:Reviving the Shriveled Lake Urmia.jpg|thumb|230px|Lake Urmia (centre) and surrounds rain-shadowed by the snowy [[Zagros mountains]] to the west.]] * The peaks of the [[Caucasus Mountains]] to the west and [[Hindukush]] and [[Pamir Mountains|Pamir]] to the east rain shadow the [[Karakum Desert|Karakum]] and [[Kyzyl Kum]] deserts east of the [[Caspian Sea]], as well as the [[Semi-arid climate|semi-arid]] [[Kazakh Steppe]].

[[Manchester]] and [[Glasgow]], for example, receive around double the rainfall of [[Leeds]] and [[Edinburgh]] respectively (although there are no mountains between Edinburgh and Glasgow). The contrast is even stronger further north, where [[Aberdeen]] gets around a third of the rainfall of [[Fort William, Scotland|Fort William]] or [[Skye]]. In Devon, rainfall at [[Princetown]] on Dartmoor is almost three times the amount received {{convert|48|km|mi}} to the east at locations such as [[Exeter]] and [[Teignmouth]].

[[Akureyri]] on a northerly [[fiord]] receives about a third of the precipitation that the island of [[Vestmannaeyjar]] off the south coast gets. The smaller island is in the pathway of [[Gulf Stream]] rain fronts with mountains lining the southern coast of the mainland. * The [[Scandinavian Mountains]] create a rain shadow for lowland areas east of the mountain chain and prevents the [[Oceanic climate]] from penetrating further east; thus [[Bergen]] and a place like [[Brekke (village)|Brekke]] in [[Sogn]], west of the mountains, receive an annual precipitation of {{convert|2250|and|3575|mm|in|sigfig=3}}, respectively,<ref>{{Cite web|url=https://www.miljolare.no/tema/luftkvalitet/kampanjer/regnsjekken07/sporsmal/?q_id=2199|title=Spør meteorologen!|website=www.miljolare.no|access-date=2019-05-07}}</ref> while [[Oslo]] receives only {{convert|760|mm|in}}, and [[Skjåk Municipality]], a [[municipalities of Norway|municipality]] situated in a deep valley, receives only {{convert|280|mm|in}}. Further east, the partial influence of the Scandinavian Mountains contribute to areas in east-central [[Sweden]] around [[Stockholm]] only receiving {{convert|550|mm|in}} annually. In the north, the mountain range extending to the coast in around [[Narvik (town)|Narvik]] and [[Tromsø (city)|Tromsø]] cause a lot higher precipitation there than in coastal areas further east facing north such as [[Alta (town)|Alta]] or inland areas like [[Kiruna]] across the Swedish border. * The [[South Swedish highlands]], although not rising more than {{convert|377|m|ft}}, reduce precipitation and increase summer temperatures on the eastern side. Combined with the high pressure of the [[Baltic Sea]], this leads to some of the driest climates in the humid zones of Northern Europe being found in the triangle between the coastal areas in the counties of [[Kalmar County|Kalmar]], [[Östergötland County|Östergötland]] and [[Södermanland County|Södermanland]] along with the offshore island of [[Gotland]] on the leeward side of the slopes.

[[Dwellingup]], {{convert|40|km|mi|abbr=on}} inland and in the heart of the ranges, receives over {{convert|1000|mm|in}} a year while [[Narrogin]], {{convert|130|km|mi}} further east, receives less than {{convert|500|mm|in}} a year. ====Pacific Islands==== * [[Hawaii]] also has rain shadows, with some areas being desert.<ref>{{cite book | last1 = Giambelluca| first1 = Tom| last2 = Sanderson | first2 = Marie | title = Prevailing Trade Winds: Climate and Weather in Hawaií| publisher = University of Hawaii Press| date = 1993| page = 62| url = https://books.google.com/books?id=EIOFE_6JdzIC| isbn = 978-0-8248-1491-5}}</ref> [[Orographic lift]]ing produces the world's second-highest annual precipitation record, {{convert|12700|mm|in|abbr=on}}, on the island of [[Kauai]]; the leeward side is understandably rain-shadowed.<ref name="Whiteman"/> The entire island of [[Kahoolawe]] lies in the rain shadow of Maui's [[Haleakalā|East Maui Volcano]].{{citation needed|date=July 2023}} * [[New Caledonia]] lies astride the [[Tropic of Capricorn]], between 19° and 23° south latitude. The climate of the islands is [[tropics|tropical]], and rainfall is brought by trade winds from the east. The western side of the Grande Terre lies in the rain shadow of the central mountains, and rainfall averages are significantly lower. * On the [[South Island]] of [[New Zealand]] is found one of the most remarkable rain shadows anywhere on Earth. The [[Southern Alps]] intercept moisture coming off the Tasman Sea, precipitating about {{convert|6,300|to|8,900|mm|in|abbr=on}} liquid water equivalent per year and creating large [[glacier]]s on the [[West Coast, New Zealand|western side]]. To the east of the Southern Alps, scarcely {{convert|50|km|mi|abbr=on}} from the snowy peaks, yearly rainfall drops to less than {{convert|760|mm|in|abbr=on}} and some areas less than {{convert|380|mm|in|abbr=on}}. (see [[Nor'west arch]] for more on this subject). ===South America=== [[File:Satellite image of Bolivia in June 2002.jpg|thumb|230px|The Andes mountains block rain and moisture from the [[Amazon basin]] to the west ([[Bolivia]]).]] * The [[Atacama Desert]] in [[Chile]] is the driest non-polar desert on Earth because it is blocked from moisture by the [[Andes Mountains]] to the east while the [[Humboldt Current]] causes persistent atmospheric stability. * [[Cuyo (Argentina)|Cuyo]] and [[Patagonia|Eastern Patagonia]] is rain shadowed from the prevailing westerly winds by the [[Andes]] range and is arid. The aridity of the lands next to eastern piedmont of the Andes decreases to the south due to a decrease in the height of the Andes with the consequence that the [[Patagonian Desert]] develop more fully at the Atlantic coast contributing to shaping the climatic pattern known as the [[Arid Diagonal]].<ref name=Bruniard>{{cite journal |last=Bruniard |first=Enrique D. |date=1982 |title=La diagonal árida Argentina: un límite climático real |language=es |journal=Revista Geográfica |pages=5–20 }}</ref> The Argentinian wine region of Cuyo and Northern Patagonia is almost completely dependent on irrigation, using water drawn from the many rivers that drain glacial ice from the [[Andes]]. * The [[Guajira Peninsula]] in northern Colombia is in the rain shadow of the [[Sierra Nevada de Santa Marta]] and despite its tropical latitude is almost arid, receiving almost no rainfall for seven to eight months of the year and being incapable of cultivation without irrigation.
