Spatio-temporal behaviours of tropical cyclones over the bay of Bengal Basin in last five decades

Present research is an endeavour to scrutinise the spatio-temporal climatic characteristics of tropical cyclones (TCs) bustle in the Bay of Bengal basin, found in RSMC-IMD data all through 1971–2020. A large number of TCs, i.e. 121 with a decadal average of 35.2 TCs has been examined for the last 50 years where depression (D) and deep depression (DD) have not been taken into account as these are less violent in nature. During the study periods, inter-annual and inter-decadal variation in cyclogenesis, landfall, length, speed, track shape and sinuosity, energy metrics and damage profile have been perceived. The study is clearly showing TCs took the northward track during the pre-monsoon season and made their landfall across the coasts of Bangladesh and…
