The western part of Rajasthan remains almost dry during south-west monsoon season. Give three important reasons in support of this statement.

The western part of Rajasthan remains almost dry during South-West monsoon season because :

(i) The monsoon winds blow from east dropping much of its moisture along the path. When they reach Rajasthan, they are almost dry.

(ii) There is no mountain high enough to check the flow of the Arabian Sea branch of

monsoon winds. The Aravalli mountains are not very high.

(iii) The direction of the Aravalli mountains is parallel to the direction of Arabian Sea winds. Hence, these winds cross over Rajasthan without giving rainfall.

(iv) The intense heat of western Rajasthan desert does not allow the condensation of moisture to take place and hence no rain is there.
