Impact of amphan cyclone on environment modification

The Amphan a Tropical super Cyclone (TC) had grown in the background of high Sea Surface Temperature of 320C-340 C, over the Bay of Bengal and in an artificially controlled pollution-free status of the Indian zone during the COVID-19 lockdown; thus providing an opportunity in examining the cyclone e...
