Abstract: | We document the flow features, which are associated with the important synoptic systems that affected the Bay of Bengal (BoB)
and its neighbourhood and controlled the convective activity there during BOBMEX. The monsoon during July and August, 1999
was subdued. It was slightly more active in the initial phase of BOBMEX that commenced on 15th July 1999 and continued up
to first week of August 1999 but weakened during the second half of August. The convection was accordingly affected, reducing
the rainfall over India. There were several active and weak spells of convection over the Bay of Bengal that manifested in
five low pressure systems, of which two became depressions. |
