How do prevailing wind affect the hot deserts?

Prevailing winds play a crucial role in the climate of hot deserts by influencing moisture distribution and temperature. In many desert regions, such as the Sahara or the Sonoran, these winds often originate from arid areas, leading to low humidity and minimal precipitation. As the winds descend, they warm up, further inhibiting cloud formation and rainfall. Consequently, the combination of dry, warm air and limited precipitation creates the characteristic hot desert environment.
