Africa

There are several important low-level jets in Africa. Numerous low-level jets form in the Sahara, and are important for the raising of dust off the desert surface. This includes a low-level jet in Chad, which is responsible for dust emission from the Bodélé Depression, the world's most important single source of dust emission. The Somali Jet, which forms off the East African coast is an important component of the global Hadley circulation, and supplies water vapour to the Asian Monsoon. Easterly low-level jets forming in valleys within the East African Rift System help account for the low rainfall in East Africa and support high rainfall in the Congo Basin rainforest. The formation of the thermal low over northern Africa leads to a low-level westerly jet stream from June into October, which provides the moist inflow to the West African monsoon.

While not technically a low-level jet, the mid-level African easterly jet (at 3000–4000 m above the surface) is also an important climate feature in Africa. It occurs during the Northern Hemisphere summer between 10°N and 20°N above in the Sahel region of West Africa. The mid-level easterly African jet stream is considered to play a crucial role in the West African monsoon, and helps form the tropical waves which move across the tropical Atlantic and eastern Pacific oceans during the warm season.
