Tropical cyclones (TCs) are one of the most extreme weather events, and the Bay of Bengal (BoB) in the North Indian Ocean experiences multiple intense TCs every year. Although a decreasing trend of yearly TC frequency was previously observed over the BoB, the mean intensification tendency has enhanced. The current study investigated the spatiotemporal variability of cyclogenesis locations and the evolution of five TC-influencing geophysical parameters in the basin during the period 1983–2023. Three distinct clusters could be identified in the BoB using K-means clustering while evaluating the spatial evolution of cyclogenesis locations. Further, a shift in dominant cyclogenesis locations towards the northern BoB was observed since 2005. Temporal analysis of geophysical variability, as investigated by ...
