Relief Rainfall

(i) Relief rainfall is caused when the mountain forces the air to rise along the up slopes of the mountain.
(ii) It takes place on the wind­ward side of the mountain and the leeward side gets very less rain and is known as the rain shadow area.
(iii) It takes place in the mountain­ous region, e.g., Western Ghats. High pressure belt to the sub polar low pressure belt.

Convectional rainfall

(i) Rainfall is caused by verti­cal ascent (convection) of heated air.
(ii) It is in the form of heavy downpour and is accompa­nied with thunder and light­ening. It is for a short time.
(iii) It takes place in the equato­rial region daily and in the interiors of the continents in summer.
