Investigation of the Effects of Climate Change on Tropical Storms and their Genesis in the Bay of Bengal
Keywords:Bay of Bengal, Coast, Climate, Cyclone, Genesis
This study investigates the impact of climate change on the genesis of storms in the Bay of Bengal. Almost all the countries of the world are facing losses due to the global warming issue and related climate disasters. Bangladesh is one of the most vulnerable countries in South Asia facing damage due to climate change. In this study, the characteristic features of genesis have been analysed using the probability formula in the small latitude area of 2 degrees. To analyse the characteristics of Genesis's behaviour, we reviewed storms that occurred in the 21st century. A reliable probability calibration is derived for every 2 degrees of latitude that explains the changes of genesis due to climate changes. For a clear view of climate change's impact on cyclone genesis, we have regenerated the study domain in a 1 by 1-degree longitude and latitude box. Which represents the clear view of genesis probability. And, it is clearly viewed that the genesis will be shifted from low latitude to high latitude.
