North Indian Ocean shows a rising trend for 0-700m depth of oceanic layer with drops during 1965 and 2000. This change in ocean heat content has obvious effects on regional Sea Surface Temperature and so on the cyclogenesis over the Bay of Bengal and Arabian Sea. Distributions of genesis and dissipation locations of storms over the Bay of Bengal are studied during three seasons of cyclonic activity viz. March-April-May (MAM: Pre-monsoon), June-July-August-September (JJAS: Monsoon) and October-November-December (OND: Post-monsoon). Deviation in Genesis locations prominently change from -7 to +5 to 0 to +7 after 1975 latitudinaly. Longitudinal deviations are found to incline towards negative trends. Mean latitude location for genesis occurs at 15.7±5.20 suffers a shift to 11.06±4.36 after 1975. A decrement is observed in monsoon storm frequency after 1964 with a rise in post-monsoon storm number. Decade of 1976-1985 is observed to hold a transition phase for SST anomaly and storm frequency anomaly over the bay.
