Abstract

The Department of Ocean Development has recently installed several moored met-ocean buoys in the Bay of Bengal and Arabian Sea to measure sea surface temperature (SST) and other near- surface atmospheric and oceanic variables every three hours. We present here a preliminary analysis of the data from one buoy in the Arabian Sea and three buoys in the Bay of Bengal, during June-August 1998, along with daily INSAT data on outgoing longwave radiation at the buoy locations. Data show that SST dropped abruptly in the eastern Arabian Sea during passage of the June 1998 cyclone. In the Bay of Bengal, SST shows prominent intraseasonal oscillations at all three buoy locations. The SST variation seems to be determined by variations in cloudiness and wind speed at the buoy location.
