Guard after Cyclone Ockhi hit the southern districts of Kerala and Tamil Nadu, resumed today -- with 102 Kerala fishermen yet to return home, a Cyclones are categorised by the maximum wind speed they generate. Cyclones with wind speeds between 165 and 220 km per hour are classified as ‘extremely severe cyclonic 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. But the case of Ockhi is peculiar. 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 ninth depression, and the third and strongest named storm of the 2017 North Indian Ocean cyclone season, Ockhi originated from an area of low pressure that formed over the southwest Bay of Bengal on November 28. Landsat 8 imageries of Pre and Post Ockhi where compared and changes made by cyclone … Strong tropical cyclone (TC) Ockhi occurred in the southeastern Arabian Sea (AS) in 2017. The ionosphere gets modulated by the upward propagating waves that originated from different meteorological processes in the troposphere such as thunderstorms, tropical cyclones etc. The present study shows that the Madden–Julian Oscillation (MJO) and warm oceanic conditions provided favourable dynamic and thermodynamic conditions for the genesis of cyclone Ockhi. This in turn has also added to their financial burden as not all children could get a job after finishing their studies. Authorities, including the National Disaster As of this morning, the cyclone is around 160 km east of Lakshadweep in the Arabian Sea. favourable conditions allowed it to quickly strengthen on December 1, According to some media reports, in Sri Lanka, some 55,000 people were reportedly affected by the bad weather while over 3,000 people have been displaced. The committee understands that forecasting rapid intensification of cyclones remains an area of concern. hours, according to Indian Meteorological Department (IMD) Director S. In the present study, an attempt has been made to understand the mechanism of cyclogenesis, RI and recurvature of the Ockhi using satellite and reanalysis datasets. A division bench of Justices R. … Update on December 5, 2017 6:50 PM: Cyclone Ockhi weakens into deep depression, may or may not cross Gujarat coast. In case you don’t know what is cyclone Ochki, here are 10 points you need to know about this latest threat: 1. The analysis is in Hindi, keeping in mind our Hindi Medium students.
