Why eastern coast of India is more prone to tropical cyclones?
1) Arabian sea is more colder than Bay of Bengal
2) The frequency of typhoons over Northwest Pacific is quite high, hence Bay of Bengal also gets higher number of cyclones.
Select the correct statement/s using codes given below:
Explanation:
The following are the reasons:-
(a) Temperature:- BOB is hotter than Arabian sea. Hot water temperature is the basic criteria for the development & intensification of cyclones.
(b) Salinity:- Arabian sea has higher salinity than BOB. Its easier to heat & simultaneously evaporate water having lower salinity.
(c) Location:- The typhoons originating in the Pacific ocean too influences the cyclones in BOB, not the case in Arabian sea.
(d) Movement:- According to IMD cyclones originating in Arabian sea are believed to move northwest. So they actually move away from Indian mainland. Cyclones do originate in the Arabian sea. The reason they are more prevalent in the Bay of Bengal is because they make landfall on the eastern side of the peninsula.
