Study of Cyclogenesis Parameters and Condition Leading to the Formation of Super Cyclonic Storm "Gonu”

Abstract

Tropical cyclones are among the most destructive natural disasters of the world and about 7% of the global tropical cyclones form in the north Indian Ocean. The present study investigates cyclogenesis parameter and conditions leading to the formation of the super cyclonic storm Gonu, which was formed over the Arabian sea using Satellite, reanalysis dataset. Cyclogenesis parameters such as Sea Surface Temperature(SST), the mid -tropospheric relative humidity (MTRH), the vertical wind shear (VWS), and other satellite parameter such as Precipitable water and outgoing long wave radiation were examined to observe the condition leading to the formation of super-cyclonic storm Gonu. Using NCEP/NCAR reanalysis data,the Vertical wind shear is computed as the difference between 200hPa and 850hPa wind and Satellite microwave measurements show sea surface temperature (SST)increase in advance of significant cyclone intensification.
