Question

What are tropical cyclones over bay of bengal

Answer 1

tropical cyclones over the bay of bengal are the cyclones that originate in the bay of bengal during the month of October. this is mainly due to the effect of the easterly jet streams.

Answer 2

The Arabian Sea and the Bay of Bengal also exercise a profound influence on climate. Though both are located in the same latitude band and receive the same amount of solar radiation from the Sun, the Bay of Bengal is much warmer than the Arabian Sea and many more storms brew over the bay. The depressions that form over the northern Bay of Bengal move northwestward across the Indo-Gangetic plains, bringing rain to most of northern India. Over the Arabian Sea, rainfall is much less on an average. The ocean plays a major role in keeping the Arabian Sea relatively dry. Recent research shows that there are two causes. First, the winds over the Arabian Sea are stronger because of the presence of the mountains of East Africa. These strong winds force a much more vigorous oceanic circulation and the heat received at the surface is transported southward and into the deeper ocean. The winds over the Bay of Bengal, in contrast, are more sluggish and the bay is unable to remove the heat received at the surface. Second, the bay receives more rainfall; it also receives more freshwater from the large rivers, especially the Ganga and the Brahmaputra, that empty into it. This freshens the surface of the bay and stabilizes the water column, making it more difficult for the winds to mix the warm, stable surface layer with the cooler waters below. In the Arabian Sea, there is no such stabilizing effect. As a consequence, the mixing with the cooler waters below is more vigorous. Since a sea surface temperature of about 28°C is ecessary for convection to take place in the atmosphere, this condition is satisfied in the Bay of Bengal but not in much of the Arabian Se. Thus, in spite of their geographical similarities, the two arms of the north Indian Ocean are strikingly different when it comes to climate.

2. More Salt Content in Arabian Sea (From one of the above answers)
3. Cyclones/Typhoons originating in Western Pacific move towards BoB but Arabian sea has less chances of such cyclones moving towards it
