Why did Tamil Nadu (only 50 cyclones) experience the least number of CYCLONE LANDFALLs along the East Coast of Peninsular India in comparison with that of West Bengal (70 cyclones), Andhra Pradesh (80 cyclones) and Odisha (100 cyclones) - in the last 1000 years?
Off the 300 cyclones over a period of 1000 years between 1900 and 2000, only one third were really severe, while the rest (nearly 200 cyclones) got weakened before striking the east coast.
Why is it so?
The same thing is happening now - that is - Cyclone Gaja - is getting weakened - before striking the east coast on 15th Nov (Wind speed not even 100 km/hour - somewhere between 60 and 80 km/hour).
What is the physics behind such weakening of the (cyclone) system?
