Solution
The hot deserts receive less than 25 cm of annual rainfall, on the average, but many places do not get even this because the hot deserts are located on western margins of continents and in the belt of Trade Winds. The trade winds become drier because the moisture gets precipitated on the eastern margins. The western margins are extremely dry because the Trade winds are blown from the interior of continents as offshore winds. The trade winds blow from cooler higher latitudes to warmer lower latitudes. Hence the winds get warmed up and the possibility of rainfall is reduced. Rainfall occurs as torrential downpours associated with violent thunderstorms due to convectional ascent of air.
