The Sahara has long been subject to periodic bouts of humidity and aridity. These fluctuations are caused by slight wobbles in the tilt of the Earth’s orbital axis, which in turn changes the angle at which solar radiation penetrates the atmosphere.
Why does the Sahara get no rain?
Hot, moist air rises into the atmosphere near the Equator. As it approaches the tropics, the air descends and warms up again. The descending air hinders the formation of clouds, so very little rain falls on the land below. The world’s largest hot desert, the Sahara, is a subtropical desert in northern Africa.
