Abstract

Problem statement: This study presents an analytical investigation for the trends of several factors such as number of death of peoples, damages of wealth, flood surge heights, wind speed and radius of the severe storm due to tropical cyclones in Bangladesh. Approach: The study is performed by conducting the field visits to cyclone site, collected data and information on damages and deaths of peoples during field visits, necessary data related to tropical cyclones obtained from available publications and news-study. The data since the period of the independence of Bangladesh (nearly 40 years) are analyzed. Results: The analyses showed that the 17 major cyclones have been occurred since 1970. Among these 17 major cyclones, the 5 cyclones were tragically severe that killed over 400 thousand peoples. It is observed that the coast of the Bay of Bengal is particularly vulnerable to tropical cyclones. It is revealed that Bangladesh is more vulnerable to devastating cyclones in the recent years because the frequency of the severe cyclones has increased remarkably. Conclusion/Recommendation: The return period of the major cyclones was decreased drastically in recent years and the country, especially, the Bengal Bay is predominantly helpless during the cyclone seasons.
