The above question gives rise to another question of ‘How cyclones are formed’. The warm and moist air near the surface of the ocean rises from the surface due to the temperature difference in the atmosphere leaving less air near the surface resulting in the formation of a low pressure region near the surface. The air in the surrounding will be of high pressure than the less air region and tends to flow to the low pressure region. The air gets cooled as it undergoes a pressure difference. This air gets warmed up and again rises. The process continues and results in the cloud formation by the cooled air. The whole system of clouds and wind spins around and that is how cyclones are formed.
The sea surface temperature of Bay of Bengal is higher than that of Arabian sea which is a primary condition for a cyclone to form. The layering of water (Water Stratification) in the Bay of Bengal caused by the difference in the properties which includes salinity, density, temperature and so on initiates the process of cyclone formation. Also the impact of the cyclone is less in Arabian sea than the Bay of Bengal because of the presence of high mountain ranges in the western part of India.

Nice to know the facts. I was not aware of this before. Thanks.
