What are the differences between Arabian Sea and Bay of Bengal branch ?? ( 5 points )


Dear Student,

Arabian sea branch
 		 Bay of Bengal branch
a. The south west monsoon after breaking on the southern part of the Peninsula in early June, causes rainfall there. The southwest monsoon moves northward in the Bay of Bengal and spreads over most of Assam by the first week of June. On encountering the barrier of the Great Himalayan Range, it is deflected westward along the Indo-Gangetic Plain toward New Delhi.

 
a. Arabian sea branch accounts for most of the rainfall in the Indian sub continent as it is larger and bigger than Bay of Bengal
 		 The advance of monsoon is faster.
c. The winds then move towards north and cause rainfall in the west of western ghats.  The winds emanating then move towards north east causing bulk of rainfall there
d. The Arabian sea branch of the south west monsoon happens in distinct phases.
 		 It then moves to the plains of Northern India.
e. It first strikes the west coast of India, then it strikes parts of Central India and then the Aravelli range where it does not cause much of the rainfall.


 The rainfall finally decreases as it moves toward the west.

Regards

Major difference between sea and bay:
Sea- the exapnse of salt water that covers most of the earth's surface and surrouns it's landamass.
Bay- a broad inlet of sea where the land curves inwards.
Now the major difference between nature of Arabian Sea and bay of Bengal is the directions in which the water currents flow plus the temperature of water and the obviously the expanse of water.
These are also the main reasons why our Eastern coastal line is more suspectible for disasters than Western.
In both Arabian Sea and bay of Bengal currents in water movie from East to West. But in case of bay of Bengal they bring the cyclones , tsunamis generated in the water towards coast.
Also the about the temperature of both water bodies, bay of Bengal being comparatively small water body plus surrounded by land on three sides approximately gives it enough to have high temperature than Arabian Sea. And as the temperature of water rises, it is all together more conducive for forming tropical cyclones which occasionally hits Eastern coastal line.
Also , there is difference in both water bodies by the role played by each in monsoon of India.
Arabian Sea has major role in onset of monsoon ( forming cell with Mascarene's high in Indian ocean ) and thus this main Arabian Sea branch of S-w monsoon breaks into two branches as Arabian Sea branch and bay of Bengal branch near southern tip of Indian subcontinent.
While bay of Bengal plays a major role in retreating monsoon , that is the reason why Tamil Nadu coast receives maximum rainfall during retreating monsoon.
