Summary
The heat budget of the oceanic surface at selected stations over the north Indian Ocean is evaluated for the three phases of MONSOON-77 by computing the insolation, effective back radiation, latent heat flux and sensible heat flux using empirical expressions. The diurnal variations of wet bulb depression, sea-surface temperature, T, and wind speed are examined for each of three phases of the monsoon over the eastern Arabian Sea and the central Bay of Bengal. The so-called ‘heat potential’ values (T≥27°C) of the upper-oceanic layer at the stations located over the offshore trough along the west coast of India are computed and related to the net heat gain at the surface. Mean temperature and thickness values of the mixed layer are also analysed. The results are discussed in relation to the behaviour of the summer monsoon over India.
Introduction
The net energy accumulated over the tropics is transported to higher latitudes by the atmospheric and oceanic circulations in maintaining the thermal equilibrium of the earth–atmosphere system. Earlier studies have indicated that the atmosphere transports more energy than the oceans. However, the studies of Von der Haar and Oort (1973) based on satellite radiation data clearly indicate that the oceans play the larger role in transporting the surplus energy from the tropics. The relative contributions of the Indian, Atlantic and Pacific oceans must clearly differ.
