Dear Student,
The Sahara is overwhelmed by two climatic systems:
a dry subtropical environment in the north and a dry heat and humidity in the south. The dry heat and humidity is described by a solid yearly temperature cycle following the declination of the sun; mellow, dry winters; and a blistering dry season going before factor summer downpours.
Deserts get under 25 centimeters (10 inches) precipitation each year. Cold deserts have short, clammy, and respectably warm summers. The winters are long and cold. Cruel polar breezes blow the snow in this chilly, dry environment.
The Sahara is the biggest hot desert on the planet, and the third biggest desert behind Antarctica and the Arctic, which are both virus deserts.
Regards.
