Rain-shadow effect: Influence of this effect:- 1) on precipitation distribution:-

a) Determine rainfall intensity:- Eg western slopes of newwau short rainy due to rain-shadow region

b) Location of Deserts:- Eg Atacama desert in South America due to rain-shadow of Andes due to rain-shadow of Andes

c) Delayed precipitation:- Eg Rajasthan on lees of Aravali, very late precipitation due to rain-shadow by Aravali of S-W monsoon direction
