"amount of rainfall decreases as we go westward from west bengal to punjab." justify with 2 suitable reasons.

Dear Student,

​ Amount of rainfall decreases as we go westward from West Bengal to Punjab because of the following reasons:

a. Monsoon winds emanating from Bay of Bengal Branch and Arabian sea branch accounts for most of the rainfall in the Indian sub continent Bay of Bengal branch causes maximum amount of rainfall and sheds most amount of its moisture in the Brahmaputra valley and Assam hills.

b .When these winds advance towards west they go on shedding moisture and that thus reduces the amount of rainfall from east to west.

c. Likewise, moisture laden winds emanating from Arabian sea branch causes maximum amount of rainfall shedding maximum amount of moisture their, in the windward side of the Western ghats because of its ascent to the south west monsoon winds .

d. South west monsoon winds do not cause rainfall in this region because of the Aravalii hills which do not cut as a barrier to these winds. 

e.  Thus, Rajasthan and Gujarat receive scanty rainfall
