Question

why do the western ghats receive more rainfall than Eastern ghats

Answer 1

Western Ghats receive more rainfall than the Eastern Ghats because
(i) Western Ghats receive rainfall from the Arabian Sea monsoon winds. As these winds blow over warm oceans, they bring abundant moisture.
(ii) The Western Ghats do not allow the winds to cross over without shedding their moisture on the Western slopes.
(iii) When these winds reach the Eastern Ghat, they are almost dry. .
(iv) Another branch of South-West monsoon i.e. the’ Bay of Bengal branch, moves parallel to the Eastern Ghats. In this way, this region is located in an unfavourable position with reference to the monsoon winds.

Answer 2

Topography and wind play an important role in the distribution of precipitation. The terms Ghats is derived from Hindi which means “river landing stairs” or “mountain pass”. The Ghats, which mean Western and Eastern Ghats, are two mountain ranges forming the eastern and western edges, respectively, of the Deccan plateau of peninsular India.
