The average annual rainfall for South Africa is about 464 mm (compared to a global average of 950 mm [3]) but large and unpredictable variations are common. Overall, rainfall is greatest in the east and gradually decreases westward, with some semi-desert areas along the western edge of South Africa. For most of the country, rain falls mainly in ...
Areas with a savannah climate in Sub-Saharan Africa, such as Ghana, Burkina Faso, [23] [24] Darfur, [25] Eritrea, [26] Ethiopia, [27] and Botswana have a distinct rainy season. [28] El Nino results in drier-than-normal conditions in Southern Africa from December to February, and wetter-than-normal conditions in equatorial East Africa over the ...
The Mediterranean climate regime resembles the climate of the lands in the Mediterranean Basin, parts of western North America, parts of Western and South Australia, in southwestern South Africa and in parts of central Chile. The climate is characterized by hot, dry summers and cool, wet winters. [10] A steppe is a dry grassland. [11]
Due to climate change, rainfall in Rift Valley has become irregular and less predictable with rainfall being more intense and extreme. Over the 20th century, including the 1970s, 1980s and 1990s, East Africa , where Rift Valley is located, had undergone a 0.05 C warming per decade. [ 3 ]
The Caribbean coast, eastward from the Gulf of Urabá on the Colombia–Panama border to the Orinoco River delta, on the Atlantic Ocean (about 4,000 km (2,500 mi)), have long dry periods (the extreme is the BWh climate (see below), characterized by very low, unreliable precipitation, present, for instance, in extensive areas in the Guajira, and ...
Under the Köppen climate classification, for tropical climates, a wet season month is defined as a month where average precipitation is 60 millimetres (2.4 in) or more. [5] In contrast to areas with savanna climates and monsoon regimes, Mediterranean climates have wet winters and dry summers.
The modern, arid Sahara. The Sahara was not a desert during the African humid period. Instead, most of northern Africa was covered by grass, trees, and lakes. The African humid period (AHP; also known by other names) was a climate period in Africa during the late Pleistocene and Holocene geologic epochs, when northern Africa was wetter than today.
A humid subtropical climate is a subtropical-temperate climate type, characterized by long and hot summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates, and equatorward from either humid continental (in North America and Asia ...
