An Analysis of Environmental Dynamical Control of Tropical Cyclone Intensity over the Bay of Bengal during 1981-2010

Abstract

The intensity of tropical cyclones (TCs) is quite sensitive to SST, which mainly determines the surface energy transfer from the ocean to the TC. However, strong surface wind stress under a TC can generate strong turbulence in the upper ocean and deepening the ocean mixed layer. This causes significant decreases in SST due to entrainment of cooler water from the thermocline into the mixed layer.
