Enlist the factors affecting the distribution of rainfall

The distribution of the rainfall is major affected based on:

i)Prevailing winds

ii)Presence of mountains

iii)Seasonal winds

Explanation:

Rainfall occurs when the gravity and size of the precipitation increases. The precipitation is produced by condensing the atmospheric water vapor. Temperature, radiation, relative humidity, and wind velocity are some factors that influence the precipitation.

The frequency, intensity and amount of the rainfall vary from place to place and time to time.

The amount of rain that will reach the ground is determined on the range of air temperatures passed by the precipitation. The precipitation occurs in the form of
