The Bay of Bengal is a semi-enclosed tropical ocean basin and forms the north-eastern part of the Indian Ocean. It is surrounded by India and Sri Lanka to the west, Bangladesh and the Indian State of West Bengal to the north, and Myanmar, the southern part of Thailand and the Andaman and Nicobar Islands of India to the east. The bay is a tropical ecosystem in a monsoon belt, highly influenced by monsoonal winds and receiving large volumes of fresh water from both river discharge and rainfall. It experiences south-west monsoon during June- September and north-east monsoon during November-February. This is a region which experiences regular depressions to super cyclone, making the coastal areas of the countries surrounding it highly vulnerable to risks and calamities.
