Detailed explanation-3: -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.

Detailed explanation-4: -PHYSICAL FEATURES Africa is the most tropical of all continents.

The Sahara Desert, the largest of its kind anywhere in the world, is over 10.4 million km2 n North to south is approx.
