. Utilizing marine meteorological data the values of 1 latent heat flux, sea surface temperature (SST) and sea minus air temperature have been computed on a grid mesh of 5° over the Bay of Bengal during September month of the contrasting Winter monsoon years 1987 and 1988. It has been found that the good winter monsoon of 1987 followed (I) higher SSTs over western Bay of Bengal; (ii) very high evaporation rate over the sea area bounded by 10°.20°N. 80°.90oE and (iii) instability in the surface layer over north and adjoining central Bay of Bengal, whereas, the bad winter monsoon of 1988 followed (i) lower SSTs over western Bay of Bengal; (ii) very low evaporation rate over the area I0°.20oN, 80°.90oE and (iii) stability in the surface layer over north and adjoining central Bay of Bengal.
