Abstract
In the present study an attempt has been made to examine the possible link between air-sea interface fluxes of heat and moisture and monsson activity over the Indian subcontinent. Computations of radiative fluxes, viz, shortwave and longwave, have been performed using semi-empirical models. Estimations of latent and sensible heat fluxes have been carried out using bulk aerodynamic method. The transfer coefficients for heat and moisture were computed as a function of atmospheric stability and wind speed. The present study shows that there is a net oceanic heat loss during the active convective period of the summer monsoon. This net oceanic heat loss produces a positive feedback for the maintenance of deep cumulus convection above the marine boundary layer (MBL). The main hindrance in establishing a possible link between the air-sea interface fluxes and monsoon activity over the Indian subcontinent is the paucity of adequate observations over the Indian seas.
