Why is drought so bad in Africa?
As the atmosphere gets warmer, the relative humidity in the African regions decreases and the drought period becomes longer and more severe. In turn, rising ocean temperatures lead to more extreme variations in weather causing increased precipitation. Rainfall events are shorter but more extreme.
Why is there no rain in Africa?
The cooler temperatures in the north weakened the high altitude Tropical Easterly Jet, which consistently brought moisture into northern Africa. Due to the weakening of the Tropical Easterly Jet, the African Easterly Jet strengthened, which indirectly inhibits rainfall in northern Africa.
