Year after year, India’s eastern coast was destroyed by super cyclone storms. After a devastating meeting with Amphan on May 20 last year, Hurricane Yaas met Odisha. A week ago, Hurricane Tauktay from the Arabian Sea claimed the lives of Maharashtra and Gujarat. However, in terms of hurricanes, the Bay of Bengal is a more active basin than the Arabian Sea.
In the past four years, 12 cyclones have formed in the Gulf, destroying the eastern coastal states of India. Within a year, the Indian coast witnessed four of them from the Bay of Bengal and only one from the Arabian Sea. Harsh Vardhan, Minister of Science and Technology and Earth Sciences, also drew attention to the increase in the frequency of cyclones in the North Indian Ocean in recent years.
Why the Bay of Bengal has become a hotbed of hurricane storms Why the hurricanes in the Bay of Bengal can be explained by the extremely low pressure generated by warm water. Meteorologists believe that the bay where the strong cyclone is formed is concave or shallow. When the strong wind pushes the flow of water, it concentrates like a storm. The Bay of Bengal is shaped like a body of water, so it is more hospitable when storms gather.
In addition, the high temperature of the sea aggravated the condition of the bay and caused the intensity of the storm. In addition, the Bay of Bengal has more rainfall due to slow wind speeds and warm air currents, maintaining high temperatures throughout the year. Perineal rivers such as the Brahmaputra and Ganges are constantly pouring in warm fresh water, making it even more impossible to mix with the cold water below.
The Bay of Bengal tends to blow hurricanes to coastal areas, causing heavy rainfall. In the post-monsoon period, the lack of air circulation from northwest India to the Gulf is another cause of hurricanes in the Bay of Bengal: Bangladesh’s most destructive hurricane was Hurricane Bora in 1970, which killed 5,000 people. East Pakistan and West Bengal. Nargis took the lives of more than 100,000 people in 2008, and 40,000 people were killed.
