The Arabian Sea circulation is unique among the world ocean circulations in that the winds over it reverse semiannually from northeasterly to southwesterly. Complex patterns of eddies and strong temperature gradients are two aspects of its response linked to the monsoonal reversal. In this paper very high resolution radiometer (VHRR) digital data from INSAT-1B was processed and enhanced to observe the sea surface features and to locate a mesoscale eddy in the Somali region. The dimensions of the eddy and the horizontal movement are within the expected range of past observations and the model simulations.
