Fun Facts About The Bay Of Bengal

The Bay of Bengal has a special place in world history and geography. It is because of several reasons.

It is bordered by the Eastern Coast in India (West Bengal and other states), and the southern coast in Bangladesh. It is also bordered by Myanmar, Sri Lanka, and the Andaman and the Nicobar Islands.

The Andaman group of islands are the larger islands in the area. The Andaman sea is separated from the bay by the Andaman and the Nicobar Islands.

On the East, a line runs from Cape Negrais located in Burma. It does so in a way that all the narrow waters between the isles are situated to the east of the line and they are excluded from the bay.

The limits are defined by the Little Andaman Island and then along with the Southwest limit of the Burma Sea. The lines are defined in such a way that narrow waters are appertaining to the Burma sea. Chittagong and Mongla are major ports of Bangladesh.

The major ports of India include Vishakhapatnam, Kolkata, and Chennai. Kolkata and Chennai are some of the biggest ports in the world. Yangon (the former capital and largest city of Myanmar) is also a major port along the Bay of Bengal.

The ecosystem of the bay that is a part of the Bengal map in Eastern India, is one of the most biologically diverse areas in the Indian subcontinent.

Only 6.5 % of the Andaman and Nicobar Islands are inhabited. The main island group in the Andaman Islands is Great Andaman. The Bay of Bengal is biologically diverse.

It has coral reefs, mangroves, estuaries, fish nurseries, and spawning areas. There are 64 large marine ecosystems in the world. The Bay of Bengal is one of them. Kerilia jerdonii is a sea snake that is found in the bay.

Facts About Bay Of Bengal's Climatic Conditions

What kind of climatic conditions prevail around the Bay of Bengal? Is a tropical storm a common phenomenon in the area? The climate around this region can be classified as a monsoon climate.

Between the months of November and April, that is in the winter season in the Northern Hemisphere, a continental high-pressure system in the north of the bay leads to the formation of the northeast monsoons. The southwest winds blow over this region in the summer months, that is, between the months of June to September.

These are rain-bearing winds. The Bay of Bengal branch of the monsoon moves northwest.

It strikes the Andaman and Nicobar Islands in the month of May. It also hits mainland India before the end of June. Tropical cyclones are common on the bay.

However, tropical cyclones are most common in this region between the months of April and May and the months of October and November. Some of the most devastating tropical storms form on this bay. The area has suffered some of the most intense and costliest storms in history.
