Abstract

The Bay of Bengal (BoB) is the import basin where tropical cyclone has been forming frequently compared to global perspective. The number and frequency of cyclone over the BoB varies year to year. The recent climatology of tropical cyclone and its track and landfall is very important to minimize casualties and damages. A statistical attempt has been made to know the seasonal number of cyclones over the BoB during 1891-2020 using BMD and IMD cyclone eAtlas data and the most devastating cyclones’ tracks of 1991, 1994, 2007, 2008, 2009 and 2020 are also drawn over the BoB. From the analysis it is found that the total number of cyclones formed over the BoB are 35, 123, 97 and 28 during pre-monsoon, monsoon, post-monsoon and winter seasons respectively whereas 58, 33, 103 and 26 for severe cyclonic storms respectively. The cyclone of all intensity over the BoB follows initially Westward/Northwestwards tracks, some of them re-curved and follows north/northeastwards tracks. Sometimes looping track is also found over the Bay of Bengal. It is also found that some cyclones have completed their journey in the BoB without landfall. This variation of cyclone makes the BoB basin more vulnerable and more challenging for forecasting of tropical cyclones.
