cyclone ockhi case study

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. NATURAL HAZARDSDE: 4333 Disaster risk analysis and assessment. Astrophysical Observatory. It is currently 100 kilometres away from Thiruvananthapuram and moving in the south-west direction. Titli cyclone is ‘rarest of rare’ What to study? Cyclones are categorised by the maximum wind speed they generate. Static Part: All about Cyclones- their origin, features and how is it different from typhoon and hurricane? DEC 1 - 9:30 AM: Cyclone Ockhi killed nine people in coastal Kerala and Tamil Nadu and damaged dozens of houses in Tamil Nadu's Kanyakumari dstrict. The southern districts of Kerala and Tamil Nadu received heavy rainfall as Cyclone Ockhi, which originated near the Sri Lankan coast, rattled through the Arabian Sea towards Lakshwadeep islands. Situation Report 2 - Cyclone Ockhi 7th December 2017 (9:00 am) A. Cylone Storm - Ockhi OCKHI system further weakened, laid as low pressure area over south coastal Gujarat and 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.” 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. It formed near southern India and Sri Lanka on November 30, 2017, moved out over the Arabian Sea, intensified to category 3 strength on December 2–3, but then weakened quickly as it moved north and closer to land. Agreement NNX16AC86A, Is ADS down? Authorities, including the National Disaster Concurrently, an abrupt reduction in the precipitation rate, accompanied by weak updraft in the eye, was observed. been destroyed while another 3,250 houses have been partially damaged. 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 dynamic mechanisms of the long-term phytoplankton bloom after the passage of the TC were investigated in this study. The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative But the case of Ockhi is peculiar. Sudevan in Trivandrum, though it is likely to lose intensity. Interested in General Knowledge and Current Affairs? Ockhi greatly changed the oceanic conditions and induced large variation in chlorophyll-a (Chl-a). accumulated cyclone energy were significantly larger for cyclone Ockhi, in comparison with the climatologi-cal cyclone records. A STUDY ON OCKHI CYCLONE AND ITS IMPACT IN KANYAKUMARI DISTRICT - WITH SPECIAL REFERENCE TO DISASTER MANAGEMENT P. GIRIJA Research Scholar of History Bharathidasan University Tiruchirappalli, Tamil Nadu. The ionosphere gets modulated by the upward propagating waves that originated from different meteorological processes in the troposphere such as thunderstorms, tropical cyclones etc. Tamil Nadu, claiming so far around 14 lives with many fishermen still top state official said, The strongest storm of the 2017 North Indian This cyclone falls under very severe cyclonic storm category and hence its effect on ionosphere has been investigated. Cyclone Ockhi continues to weaken gradually and is now seen as a Deep Depression over east-central Arabian Sea. It is now moving closer to Lakshadweep. Ocean cyclone season, Ockhi originated from an area of disturbed weather near Sri Lanka on November 29, Proximity to land initially prevented significant strengthening; however, as it entered the Arabian Sea, Ockhi greatly changed the oceanic conditions and induced large variation in chlorophyll-a (Chl-a).
