Chronological History and Destruction Pattern of Tornados in Bangladesh

Abstract

Abstract:Bangladesh has been facing the severe tornado incidents from the historical ages due to its geographical location.In recent years, it becomes more frequent; even hit the land more than six times in a year. The study has been conducted based on critical review and analysis of secondary data. This review paper has been carried out to recognize the chronology and frequency within a certain period of time to identify the destruction pattern of tornadoes in the country. From 1865-2014 the country has been faced more than 250 tornadoes reported, in which 20 events or more were enormously deadliest in fatalities and damages in the world history. Within these, 116 events has been recorded minimum 01 life lose. The recounted data figured out these events causes more than 9667 no. of human lives lost, injured 74702 and affected another 586306 lives of human. The regularity of tornado increases last few decades, basically after 1960. Sequential development of human civilization with global warming inspires the amount of warm and dry air is that responsible for tornado occurrence. During the tornado, the heavy rainfall is formed for moist weather which contains huge water drops. Sudden large runoff pollutes the existing local water system and the crop lands in the affected area. Improved weather forecasting, warning system, tornado risk zoning maps and ensuring proper building code for infrastructure may help to reduce the losses.
