Description The response of the eastern Arabian Sea to prevailing winds during an upwelling event, in the peak of southwest monsoon, was studied at both coastal and open ocean environment based on the data collected as a part of the Indian Joint Global Ocean Flux Studies (JGOFS) programme. Analysis of wind measurements indicated active upwelling along the southwest coast of India, which gradually propagates towards north. While the dominant long-shore component of the wind induces upwelling in the south, the cross-shore component is instrumental in modifying the density structure of the surface layer, especially in the north, to produce retarding effect. In open ocean, the wind maximum around 17 degrees N and 64 degrees E indicates the axis of the Findlater Jet. The observed surfacing and deepening of the isotherms on either side of the axis are the signatures of the upwelling and sinking associated with the Findlater Jet.
