Why india east coast more prone to cyclone than west coast?
Answers
. East coast of India faces the Bay of Bengal while the west coast of India is situated on the shores of Arabian Sea.
Bay of Bengal is very active in the months of October to December during the end phase of South west monsoon and whole of North east monsoon period.
During these periods, the easterlies pick up moisture from BoB and the remnants of typhoons from Malay peninsula enter the waters of BoB and form low pressure troughs. They further intensify in strength due to favourable warm temperatures of sea and increased sea travel.The cyclones then travel in eastern direction due to prevailing easterlies and cross the shores of eastern states of India. The entire east coast from Tamil Nadu to West Bengal is prone to cyclones. Cities like Chennai, Nagapattinam, Rameshwaram, Srikakulam, Gopalpur, Cox Bazaar(Bangladesh) are extremely prone to cyclones.Cyclones do originate in Arabian sea but they mostly tend to move away from west coast of India towards Oman, Yemen or Somalia. This is due to strong winds from BoB and peninsular India pushing the cyclones/depressions further away.
