Relationship between summer monsoon rainfall and cyclogenesis over Bay of Bengal during post-monsoon (October-December) season
Sadhuram, Y.; Maneesha, K. (Indian Academy of Sciences, 2016)In this study, an attempt has been made to examine the relationship between summer monsoon rainfall (June-September) and the total number of depressions, cyclones and severe cyclones (TNDC) over Bay of Bengal during the ... -
Role of physical processes in the distribution of chlorophyll a in the northwest Bay of Bengal during pre and post-monsoon seasons
Sarma, V.V.; Sadhuram, Y.; Sravanthi, N.A.; Tripathy, S.C. (Indian Academy of Sciences, 2006)Distribution of Chlorophyll–a (Chl–a) in the north west Bay of Bengal during pre-monsoon (4-15th and 21-28th March) and post-monsoon (5-12th and 13-19th October) seasons of 2000 has been reported from MODIS. These are ... -
Role of the Indian Ocean on the southern oscillation, atmospheric circulation indices and monsoon rainfall over India
Sadhuram, Y.; Wells, N.C. (Taylor and Francis, 1999)The relationship between the sea surface temperature (SST) in a small region (0-5 N; 80-85 E) in the Eastern Equatorial Indian Ocean and Indian monsoon rainfall and monsoon Indices (M1, U200) has been examined. The role ... -
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 ... -
