Areas receiving rainfall less than 20 cm in india map
Answers
Answer:
Areas receiving rainfall "less than 20 cm" in India are regions of "Western Rajasthan, Northern Kashmir, Deccan Plateau, and Punjab". Rainfall is especially very scanty in the Rajasthan region due to various factors like lack of any orographic barriers in the region that can make use of the south-west monsoons. Other reasons for lack of precipitation include the "Bay of Bengal" branch of monsoon becomes dry as it crosses and makes its way to Rajasthan and surrounding areas after crossing the northern plains . it also does not receive any rain from the cyclonic storms in states like Andhra, Tamil Nadu etc because of its geographical location that is far away from these states. Also, the climate of these states is dry and arid that increases the "moisture holding capacity" of the rain bearing winds and thus, no rainfall.
