Cyclone is a natural disaster that blows Over Bay of Bengal (BoB) and makes masses of devastation. Assessment of its characteristics and prediction of its mobility are extremely difficult tasks. Wind and pressure are the most significant factors that decide cyclone genesis, propagation and intensity. Physical understanding of the relation between two significant parameters during cyclone is very complicated and is elusive through modelling and prediction. Data sourced from International Best Track Archive for Climate Stewardship (IBTrACS) were analyzed to know wind and pressure relation and cyclone tracking. Cyclone spatial wind pattern is determined using the Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2). Analysis shows that wind and pressure are related inversely and is complex in nature. Spatial analysis using MERRA-2 demonstrates asymmetric wind pattern. IBTrACS data (from 2005 to 2016) show the majority of the cyclone intensity is concentrated on north-eastern side of BoB which fact could be attributed to high subsurface heat storage. Inter comparison of different cyclones during the period 2005-2016 was also made and found in support of the wind pressure relation.
