Role of upper ocean parameters in the genesis, intensification and tracks of cyclones over the Bay of Bengal
Maneesha, K.; Sadhuram, Y.; Prasad, K.V.S.R. (Institute of Marine Engineering, Science & Technology, 2015)It is well known that the frequency of cyclones is about four times higher over the Bay of Bengal when compared with the Arabian Sea. Most of the severe cyclones during pre-monsoon (April and May) and post-monsoon (October ... -
East India Coastal Current induced eddies and their interaction with tropical storms over Bay of Bengal.
Patnaik, K.V.K.R.K.; Maneesha, K.; Sadhuram, Y.; Prasad, K.V.S.R.; Murty, T.V.R.; Rao, V.B. (IMarEST publishers, 2014)Eddies of about 10 to 500km in diameter, persisting for periods of days to months are commonly referred to as mesoscale eddies in oceanography. Energetic eddies are frequently found in the vicinity of faster flowing currents ... -
