Abstract : Typhoons are tropical revolving storms. They are called `Cyclones' in English, when they occur in the Indian Ocean area. The coastal regions of Bangladesh are subject to damaging cyclones almost every year. They generally occur in early summer (April-May) or late rainy season (October-November). Cyclones originate from low atmospheric pressures over the Bay of Bengal. Due to unique geographic location, Bangladesh suffers a lot from devastating tropical cyclones frequently. The funnel-shaped northern portion of the Bay of Bengal amplifies the storm surge of landfilling tropical cyclones, affecting thousands of people. Some of the most devastating natural disasters in recorded history with high casualties were tropical cyclones that hit the region now comprising present-day Bangladesh. Among them, the 1970 Bhola cyclone alone claimed approximately 300,000 to 500,000 lives, making it the deadliest tropical cyclone on record. Tropical cyclones affecting Bangladesh have killed about 1.54 million people in Bengal (including India ruled Bengal). This study tried to explain the historical and environmental overview of each and every cyclone took place in the greater Bengal territory from 1582 to till date
