Explanation:

One of these causes is the separation of the region from oceanic moisture sources by topography or by distance.
A second general cause of aridity is the formation of dry, stable air masses that resist convective currents Widespread rains almost unknown over large parts of the hot deserts, most of the precipitation coming in violent convectional showers that do not cover extensive areas.
Large diurnal ranges in deserts are also associated with the meager vegetation cover, which permits the barren surface to become intensely heated by day.
