| Abstract: | Bangladesh is highly susceptible to tropical cyclones. Unfortunately, there is a dearth of climatological studies on the tropical
cyclones of Bangladesh. The Global Tropical Cyclone Climatic Atlas (GTCCA) lists historical storm track information for all
the seven tropical cyclone ocean basins including the North Indian Ocean. Using GIS, tropical cyclones that made landfall
in Bangladesh during 1877–2003 are identified and examined from the climatological perspective. For the convenience of study,
the coast of Bangladesh is divided into five segments and comparisons are made among the coastal segments in terms of cyclone
landfall and vulnerability. There is a large variability in the year-to-year occurrence of landfalling tropical cyclones in
Bangladesh. Most of the tropical cyclones (70%) hit in the months of May–June and October–November generally show the well-known
pattern of pre- and post-monsoon cyclone seasons in that region. |
