Question
The amount of rainfall in a year at Jaisalmer rarely exceeds 12 centimetres. State the reasons.
Solution
Following are the reasons for low rainfall at Jaisalmer :
(i)Jaisalmer lies to the west of Aravallis in Rajasthan. The Bay of Bengal branch of monsoon becomes dry when it reaches here.
(ii)This area lies in the subtropical high-pressure belt, where winds have lesser moisture contents which do not give rainfall.
(iii) This area lies away from the high Himalayas and hence does not get rainfall at all.
