Role of Ocean Heat Content in the Rapid Intensification of Cyclone Amphan (2020) over the Bay of Bengal
Role of Ocean Heat Content in the Rapid Intensification of Cyclone Amphan (2020) over the Bay of Bengal Author:Kritajno Bhattacharya Abstract A major forecasting challenge in the North Indian Ocean is the rapid intensification (RI) of tropical cyclones, especially in the Bay of Bengal, where coastal communities are extremely vulnerable. The main indicator of cyclone intensification has historically been sea surface temperature (SST). Since it captures the total thermal energy available for cyclone growth outside of the surface layer, subsurface ocean heat content (OHC) has lately been acknowledged as a more accurate metric. This study examines how OHC contributed to Super Cyclonic Storm Amphan's (2020) quick intensification over the Bay of Bengal.We'll examine the atmospheric and oceanic factors that contributed to Amphan's abrupt intensification using Tropical Cyclone Heat Potential datasets, in-situ Argo float observations, and best-track records from the India Meteorol...
