Question

Western Rajasthan receives no rain from the Arabian Sea branch of the South West Monsoon winds.

Answer 1

The Arabian Sea branch of the South-West Monsoon strikes the Saurashtra peninsula and passes over western Rajasthan, parallel to the Aravalli range. It hardly causes any min in Western Rajasthan because it undergoes thermal heating on blowing over the hot sands and gets unsaturated. As the area lies on the lee ward side of the Aravalli range, no rain is caused.
