The rainfall zones are, however, somewhat deflected from a due west-to-east direction, the drier northern conditions extending southwards along the east coast, and those of the south northwards along the west.
The climate is characterized by hot, dry summers and cool, wet winters. [10] A steppe is a dry grassland. [11] Subarctic climates are cold with continuous permafrost and little precipitation. [12] The tropical zones have the highest number of storm events followed by the temperate climate.
The Köppen climate classification system was modified further within the Trewartha climate classification system in 1966 (revised in 1980). The Trewartha system sought to create a more refined middle latitude climate zone, which was one of the criticisms of the Köppen system (the climate group C was too general). [10]: 200–1
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.
South Africa is a sunny country, averaging 8–10 daily sunshine hours in most regions. [2] The average annual rainfall for South Africa is about 464 mm (compared to a global average of 786 mm [3]) but large and unpredictable variations are common. Overall, rainfall is greatest in the east and gradually decreases westward, with some semi-desert ...

This diversion weakens the equatorial upwelling zone in the eastern equatorial Atlantic, resulting in warmer waters in the pelagic. On the other end of the spectrum when insolation in North Africa is at a minimum due to the precession cycle, the diversion of the easterly trade winds is relatively weak.
