Abstract :

The annual and seasonal variations of surface heat fluxes over the northern Indian Ocean is studied utilising OA flux data (1983-2007). The analysis showed much higher amount of net heat gain compared to previous estimates based on other data sets which is consistent with Yu et al. (2007). There is also substantial variations in heat flux with other seasons. The net heat flux is found to be positive in both Arabian Sea and Bay of Bengal during southwest monsoon, whereas previous studies showed net heat loss during this period. The latent heat flux is found to be 15-20% higher in the southern Indian Ocean especially during southwest monsoon compared to earlier estimates. This suggest that the moisture flux from southern hemisphere could be much greater than previously estimated
