Bay of Bengal is associated with disturbances like tropical cyclones and monsoon depressions during pre and post monsoon and southwest monsoon seasons respectively.
Monsoon depressions are cyclonic atmospheric vortices with outer radii near 1000 km that form within the larger-scale monsoon circulations of India and other regions. Most monsoon depressions form to the east of India over the Bay of Bengal and generally last a few days. It is not uncommon that MDs move north-westwardalongthemonsoontroughandreach as far as northwestern IndiaPakistan and produce.
Monsoon depression over the Bay of Bengal could be one of the manifestations of the differential rates in the observed warming trend of the Indian Ocean basin.

Most of the Bay of Bengal depressions form within the monsoon trough.
It is shown that there is an out-of-phase variation in the number of MDs over the BoB and the PDO except during 19271945. Most Monsoon depressions form over the warm waters of the Northern parts of Bay of Bengal within the moist environment of monsoon air. Observations of 408 monsoon low-pressure systems MLPSs including 196 monsoon depressions MDs that formed in the Bay of Bengal during the 19512007 period and the gridded analysis of daily rainfall fields for the same period were used to identify the association of antecedent rainfall 1 week average rainfall prior to the genesis of MLPS with the genesis of MLPS and length of.
