| Abstract | The Somalian jet drives the strong Somalian current in the western Arabian Sea along the Somalian coast. The Great Whirl is a feature of this coastal current eddy structure. In these eddies, spatially, the SSTs differ by a magnitude of 3o C within a distance of around 200 km. These differences cause a distinguished characteristics of air-sea interaction processes within the area spanning these eddy structures. Using the ICOADS ship dataset, analysis of characteristics of the air-sea interaction processes show a clear variability between excess monsoon years and deficient monsoon years. The surplus monsoon years composite and deficient monsoon years composite of meridional profiles (along 57o E in the WAS region) of variables like, SST, meridional wind speed at 10m, air temperature at 10m, sea-air temperature difference, surface layer stability, potential vorticity tendency and other oceanographic variables show a clear difference exhibiting a high inter-annual variability of air-sea interaction in this region. |
