Study of the influence of surface energy budget of north Indian' Ocean on the behaviour of Indian summer monsoon

Abstract

The probable influence of the fluctuations in the energy budget of north Indian Oceanic surface on the general behaviour of Indian summer monsoon during July is investigated in the present study. Normals of the energy budget components as, monthly heat gain by the ocean, solar radiation absorbed by the ocean and the net infrared radiational exchange at the surface, following Budyko's method, latent heat flux and sensible heat flux, following bulk aerodynamic method during July are evaluated using the available marine climatological data over north Indian Ocean. Deviations of energy budget components from their respective normals during break monsoon period are showing significant differences, which are discussed in terms of the behaviour of the summer monsoon. Charts of energy budget components are presented and the associated features are discussed.
