| Abstract | The Arabian sea saw the formation of 4 Very Severe Cyclonic Storms (Maximum sustained wind speed exceeding 64 kt) for the first time in the satellite era (Post 1965). In the recorded history of 1891-2019, the year 2019 became only the second such year after 1902 that witnessed the development of 4 cyclones. The only Super Cyclone formed in the Arabian sea previously is 'Gonu' which formed in 2007 made two landfalls, first over Oman and second over Iran. The Year 2019 witnessed another such Super Cyclone over the Arabian Sea in the last week of October. However, this Super Cyclone weakened over the sea itself without making any landfall. As these cyclones are formed over the deep oceans, their analysis is largely dependent on Satellite imagery. Super Cyclone 'Gonu' was tracked using Kalpana-1 and METEOSAT-7 geostationary satellites. Super Cyclone 'Kyarr' was tracked simultaneously using three Geostationary satellites viz. INSAT-3D, INSAT3DR and METEOSAT-8. The rapid scan imagery of INSAT-3DR was also made use of. The present case study makes use of these satellites imagery and products to understand the formation, intensification and weakening of Super Cyclone 'Kyarr' vis-a-vis Super Cyclone 'Gonu' over the Arabian Sea. |
