The committee understands that forecasting rapid intensification of cyclones remains an area of concern. The storm … Earlier studies have shown that MJO, an oceanic-atmospheric phenomena, plays a vital role in the genesis of cyclones in the north Indian Ocean by providing favourable background atmospheric conditions. The present study is to make an attempt in the analysis of the post livelihood status of the fishermen community due to Ockhi cyclone in Kanyakumari district. The case of Cyclone Nivar is similar to that of Cyclone Ockhi in several ways. This cyclone falls under very severe cyclonic storm category and hence its effect on ionosphere has been investigated. We found that unusually warm ocean temperatures favoured the evolution of Ockhi from a depression to cyclone in 9 hours and then to a very-severe-cyclone in 24 hours.” Editor's note: Cyclone Ockhi, the first severe storm in almost 40 years to have travelled about 2,400 kilometres from the Bay of Bengal to as far as the Gujarat coast, cut a path of devastation and left in its wake shattered livelihoods and broken families.This, part two of a three-part series, examines the lack of adequate measures taken to tackle the effects of the cyclone.
