Western Coast of India less vulnerable to Cyclones

Subject – Geography

Context – More cyclones in Arabian Sea recently, Minister tells RS. This has not measurably increased threat to western coast.

Concept –

The eastern coast remained far more vulnerable to “extremely severe cyclones” than the western coast, but there was nevertheless “no significant trend” in the frequency of extremely severe cyclonic storms (ESCS).
“The increase in frequency of cyclones over the Arabian Sea has not posed a corresponding increase in the coastal vulnerability along the west coast since most of such cyclones forming over the Arabian Sea were making landfall over the coasts of Oman, Yemen etc and hence the threat to Gujarat & Maharashtra coasts remains same.
Low-lying coastal belts of West Bengal, Odisha, Andhra Pradesh and Tamil Nadu and Puducherry were more prone to the impact of these systems.
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 into the deeper ocean.
