Statistics show that eight out of every ten devastating tropical cyclones in the history of the world occur in the Bay of Bengal. The sea is the birthplace of 26 of the 36 worst tropical cyclones in recorded history. Numerous cyclones including 'Bhola', 'Super Cyclone 1999', and 'Amphan' have come up from the Bay of Bengal. Born in the Bay of Bengal, Indian State West Bengal, Odisha and Bangladesh have been the hardest hit by the cyclone. In the last two hundred years, 42% of the world's tropical cyclones have hit in this region. At least 20 lakh people lost their lives. The southern part of India has to endure the onslaught of sea storms from three directions, east, west, and south. However, in comparison to the Arabian Sea, the Indian Ocean, far more natural disasters come from the Bay of Bengal to the land of India.

West Bengal, Orissa, Andhra Pradesh, and Tamil Nadu are among the states in India that are regularly affected by cyclones. The Bay of Bengal occupies only 0.6% of the world's total ocean area. According to geologists, the triangular shape of the Bay of Bengal and its shallow bottom is the source of cyclones. The rate of cyclone concentration in the Bay of Bengal is at least five times higher than in the Arabian Sea. The temperature and humidity of the Bay of Bengal are also ideal for cyclone preparedness. The water temperature in the Bay of Bengal is 26 degrees Celsius throughout the year. As well as constant rainfall retains the moisture of this part. As a result, it does not take long to turn from low pressure to the cyclone and from the cyclone to cyclone. In addition, cyclone preparedness has become more fertile in the heart of the rough Bay of Bengal due to global warming.
