In spite of being close to the Arabian Sea, why does Rajasthan remain

1.	In spite of being close to the Arabian Sea, why does Rajasthan remain dry?OrWhy Rajasthan remains dry inspite of being close to Arabian Sea?
Answer» The western part of Rajasthan is desert. It gets an annual rainfall less than 20 cms. This is due to the following reasons: Rajasthan is under the influence of S.W. summer monsoons. The Aravallis system lies parallel to the direction of S.W. monsoons coming from Arabian Sea. So this mountain system is unable to check these winds. So western Rajasthan is practically dry. The southern part gets some rainfall. This area lies at a great distance from the Bay of Bengal. The Bay of Bengal monsoons become dry and lose their moisture when they reach Rajasthan. This area is away from the Himalayan region. So it does not come under the influence of monsoons giving rain in Sub-Himalayan region.
