Topic– Part of static series under the heading – “Cyclones”
1) What are the conditions necessary for formation of cyclones? Explain why cyclones that emerge in Bay of Bengal are much more destructive than the ones that emerge in Arabian Sea?(250 words)
Key demand of the question
The question expects us to bring out the essential requirements of atmospheric conditions that lead to formation of cyclones. Thereafter, based on those reasons we need to discuss why cyclones are more destructive in Bay of Bengal vis a vis Arabian Sea.
Structure of the answer
Introduction – Explain what cyclonic systems are
- Discuss the pressure, temperature etc which are required for the formation of a cyclonic system
- Mention the reasons why cyclones are more destructive in Bay of Bengal vis a vis Arabian Sea
- Temperature difference: The low pressure system of cyclone need continuous supply of heat energy and as the Bay of Bengal is warmer than Arabian sea, it is able to provide the heat energy needed to sustain the low pressure system.
- Cyclones from Pacific ocean: The low pressure system originating from the pacific ocean also travel towards left to Bay of Bengal and hit the western coast from Bay of Bengal.
- Peninsular Landmass: The cyclones originating from the Bay of Bengal side are not able to sustain while travelling above the peninsular landmass due to absence of energy of evaporation and weakens while reaching the Eastern coast.
- Direction of the cyclones: The direction of the low pressure system are from right to left, hence the Arabian sea originating cyclones are not able to hit the coastal areas.
