Energy exchanges between ocean and atmosphere in relation to southwest monsoon performance over India

Abstract

Energy fluxes over Indian seas have been computed for pre-monsoon and monsoon months of the years 1987 and 1988 using bulk aerodynamic equations with exchange coefficients which vary with wind speed and stability, The years 1987 and 1988 have bee~ chosen due to the constrasting nature of the performances of Indian summer monsoon during these years. Besides energy fluxes several other oceanographic parameters, viz., SST, sea-air temperature difference, 'Bowen ratio'and 'rate of wind work' have been computed and examined. The distributions of these parameters over Indian seas during 1987 and 1988 reveal several constrasting features. Some of these features provide predictive indications of monsoon performance.
