Less Rainfall in Rajasthan: One sub¬branch of the Bay of Bengal moves along the Ganga plains westwards to reach Western Punjab and Western Rajasthan. The intensity of moisture in these winds gets exhausted as they reach Western Rajasthan. Therefore, there is less of rainfall in Rajasthan. The Arabian Sea is obstructed by the Aravalli ranges. That is another reason due to which the Western Rajasthan, i.e. Bikaner, Jaisalmer, etc. get less rainfall.
