Question
The Coromandel coast has more rainy months but less rainfall than the Konkan Coast. Why?
Advertisements
Solution
Konkan Coast faces on-shore S. W. Monsoons during summer. These moist laden winds give heavy rainfall (more than 300 cm.). But these winds do not give much rainfall on the Coromandel Coast as it lies in the rain shadow of Western Ghats. Coromandel Coast also receives winter rainfall from N. E. monsoons, but on Konkan Coast these winds are off. shore and do not give any rainfall. N. E. Monsoon is a dry wind as it blows from the land. Thus, Coromandel Coast gets rainfall in both the Seasons, but the total blows amount is less than that of Konkan Coast.
