. (i) western Rajasthan and part of Gujarat are desert type regions with
extreme climate. Intense thermal heating makes the desert land very
dry.
(ii) The Arabian Sea branch runs parallel to Aravallis, providing no barriers
to the clouds, leaving it again a dry region.
(iii) The Bay of Bengal branch is unable to reach up to western part and
in winters even western disturbances also hardly give any rains to this
region.
(iv) The leeward side of the western Ghats also lies in the rain shadow of
S.W. monsoon.
(v) With the result, areas lying at the same latitude are unable to receive
rains, if they are on the leeward side of the Western Ghats.
