The Bay of Bengal, the largest bay in the world, is named after the Indian state of Mongolia, with a total area of 2.172 million square kilometers, an average depth of 2,586 meters and the deepest point of 5,258 meters. The famous islands are Sri Lanka Island, andaman islands, Nicobar Islands and Phuket.

The coastal countries include India, Bangladesh, Myanmar, Thailand, Sri Lanka, Malaysia and Indonesia. Some major rivers in India and Myanmar flow into the Bay of Bengal. The famous rivers are Ganges, Brahmaputra, Irrawaddy, salween and Krishna.

The Bay of Bengal is embedded in Sri Lanka in the west, bounded by India in the north, Myanmar and Nepal-Nicobar Ridge in the east, and connected with Punta Dundera at the southern tip of Sri Lanka and Punta Ulleure at the northwestern tip of Sumatra in the south. The exposed part of the Andaman-Nicobar Ridge connects andaman islands in the north and Nicobar Islands in the south, which separates the Bay of Bengal from the Andaman Sea and is an important passage between the Pacific Ocean and the Indian Ocean.

the trade along the bay of Bengal is very developed. Famous ports such as Kolkata in India, Chittagong in Bangladesh, Yangon in Myanmar, Phuket in Thailand, Penang in Malaysia, Banda Aceh in Indonesia and Jaffna in Sri Lanka are all located in this sea area.

The Bay of Bengal is a place where tropical storms breed. It is generally believed that most of these storms occur in tropical areas with 5 ~ 25 north latitude. Tropical storms produced in the western Pacific often hit the Philippines, China, Japan and other countries, which are called typhoons; Tropical storms that occur in the Atlantic Ocean and often attack the United States, Mexico and other countries are called hurricanes.

from April to October every year, that is, at the turn of local summer and summer and autumn, violent storms often sweep with the tide, causing huge waves and roaring towards the mouth of Ganges-Brahmaputra River, with high winds and high waves, causing heavy rains, which often cause great disasters.
