Question

Differentiate between Arabian sea branch and bay of Bengal branch

Answer 1

The answer is below . It tells the difference between Arabian sea branch and bay of Bengal branch

Answer 2

Arabian Sea and Bay of Bengal is similar in so many aspects, like location is on same latitude bands, semi-enclosed nature, opening on the southern side and exposure to the changing monsoon winds (ie, South-west and North-east monsoon). Both receive similar kind of solar radiation at the top of troposphere. In spite of this there are striking dissimilarities observed between both.

The most important is that winds over the basin especially during summer monsoon is different. Second, the precipitation exceeds evaporationin the Bay of Bengal whereas evaporation exceeds precipitation in the Arabian Sea. The annual rainfall over the Bay of Bengal is more than 1-3m (even more than that in Andaman Sea) while in Arabian Sea it is barely 1m. The average run-off to Bay of Bengal is much more than Arabian Sea. Hence the surface water will remain always fresher than Arabian Sea (Arabian Sea is having lesser run-off of river). Because of this the salinity of Bay of Bengal surface water will be lesser than that of other basin. Due to the river outflow the Bay of Bengal remains turbid and contains sediments most of the months especially during rainy season.
