The advent of satellite scatterometer technique for derivation of surface wind field helped meteorological community to gather widespread surface observational data over a broad oceanic area. Utility of surface relative vorticity derived from Quickscat satellite scatterometer data has been explored and an objective technique described in this study found to be an effective tool in identifying and monitoring genesis of tropical cyclone over Bay of Bengal. Higher values of maximum average surface relative vorticity over 220km x220km area with increase in order of 5x10-5 s-1 during 48 to 72 hrs prior to cyclone development are favourable for cyclogenesis over Bay of Bengal.
