"A category 4 cyclone has a wind speed of 209-251 kmph, and is referred to as an extremely severe cyclonic storm, while a category 5 cyclone has a wind speed of more than 252 kmph, and is referred to as a super cyclone.(PTI)
The severe cyclonic storm which made landfall south of Alibag in Maharashtra’s Raigad district on Wednesday at 11.30 am is an indication of an increasing frequency of severe cyclones developing in Arabian Sea in the past decade, a trend that studies have linked to climate change.
In the past two years, there have been seven cyclones in the Arabian Sea, though, according to India Meteorological Department (IMD), the ratio of cyclones in the Arabian Sea and the Bay of Bengal — which just witnessed the destructive cyclone Amphan on May 21 — is 1:4.
The Intergovernmental Panel on Climate Change (IPCC) last year came out with a special report, Ocean and Cryosphere in a Changing Climate, in which it said that extreme rainfall and extreme sea level events associated with some tropical cyclones are being seen to have a cascading impact on coastal areas." ～Jayashree Nandi @Hindustan Times
