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...

                                            INDIA WEATHER DESK DAILY DISTRICT WEATHER BULLETIN – WEST BENGAL Date of Issue: 01.08.2025 (1700 IST) Valid for 24 hours: 02.08.2025 0530 IST to 03.08.2025 0530 IST SYNOPTIC SITUATION (as of 01.08.2025, 2200 IST): The monsoon trough at mean sea level continues to run close to its normal position and is passing through Rajasthan, Madhya Pradesh, Jharkhand, and Gangetic West Bengal. A cyclonic circulation lies over coastal Odisha and adjoining northwest Bay of Bengal extending up to mid-tropospheric levels. Moisture incursion from the Bay of Bengal is strong over southern parts of West Bengal due to southwesterly winds. No significant low-pressure area has formed in the Bay of Bengal, but model guidance indicates possible consolidation of cyclonic circulation over north Bay in the next 3–4 days.
