State Status – Climate Change
Rajasthan is situated to the north of the Tropic of Cancer. Hence the state is located in the sub-tropical zone. Only Dungarpur and some part of Banswara district lie in the tropics. The Aravalli mountain ranges have divided Rajasthan into two parts from the point of view of climate. The Aravalli mountain ranges do not become a hindrance in the way due to the direction of the monsoon winds, so the monsoon winds come out straight and do not make it rain. Thus, the western region receives scanty rainfall due to being a shadow region of the Aravallis.
