The book examines to identify, causes, historical background and frequency of tropical cyclones over the Bay of Bengal for the last 100 years. It is an attempt to analysis the trends of cyclonic frequency during a particular month and year from the period of 1908-2008. Efforts have been made to understand the behavior of the perfect condition and formation of tropical cyclone, and formation area and track of land fall in the Bay of Bengal. GIS method (ArcView3.3 and Arc GIS 9.2 and ERDAS IMAGINE 8.4) has been used to find out the formation area and tracks of tropical cyclones over the Bay of Bengal. Most of the Cyclonic Storm formed in the Bay of Bengal during May to December with the highest frequency in November followed by October.
