Abstract: Tropical cyclones are among the most dangerous and vulnerable natural disasters faced by people all over the world. The Bay of Bengal (BoB) is a potentially active zone for tropical cyclone generation. Eddies are well-known for their role in the abrupt strengthening of tropical cyclones. The influence of the eddy on the intensification of cyclone Jal in the BoB is investigated in this study utilising sea level anomaly (SLA) data from satellite altimetry. In the paper, We reported the evolution of mixed layer heat budget terms for the Jal cyclone's warm-core eddy area, as well as the influence of oceanic processes responsible for surface ocean changes (up to the MLD) connected with the cyclone's warm-core eddy. To understand the mechanisms and dominant processes associated with changes in the ocean mixed layer (i.e. during the active cyclone period, pre and post of the cyclone period) heat budget analysis is utilized. The present study exemplifies the role of a post-monsoon cyclone (Jal) is impacting the Bay of Bengal variability of surface Physical Oceanographic variables and associated processes.
