Air sea exchange of fluxes and Indian monsoon from satellite data
(PORSEC 2002 Secretariat; Bogor; Indonesia, 2002)Latent heat flux (LHF) over the tropical Indian Ocean (25 N to 25 S: 35 degrees E to 120 degrees E) for ten years from 1988 were computed using bulk parameterization method by making use of both monthly and weekly values ... -
An ENSO beginning in the year 2000?
(NIO, Dona Paula, Goa (India), 2000)Several models have been developed over the last few decades to predict the advent of new ENSO events several months in advance of the actual event. None of the models have predicted a warm event beginning by the year 2000. ... -
Annual and interannual variation of precipitation over the tropical Indian Ocean
(American Geophysical Union, 1997)The annual and interannual variability of precipitation over the tropical Indian Ocean is studied for the period June 1986 to December 1990 using the data retrieved from the Indian National Satellite (INSAT). The seasonal ... -
Climate of the northern Indian Ocean and associated productivity
(International Society for Tropical Ecology, 1985)The climatic factors likely to influence the phytoplankton production in the northern Indian Ocean are examined. The major cause for the high productivity of the Arabian Sea is the nutrient enrichment of the euphotic zone ... -
Distribution of Bowen ratio over the north Indian Ocean
(India Meteorological Department, 1986)The monthly averages of Bowen ratio over the north Indian Ocean have been computed Three typical situations in the months of January May and September are taken for the present study Month to month differences in the Bowen ... -
Factors controlling January–April rainfall over southern India and Sri Lanka
(Springer, 2011)The factors controlling rainfall over southern India and Sri Lanka between January and April, i.e. outside of the southwest and northeast monsoons are explored. This period accounts for 20% of annual precipitation over Sri ... -
Fluctuating monsoonal precipitation as revealed by foraminiferal variations in a core from shelf regime off Karwar (India)
(Current Science Association, 1988)Variations in the percentage frequency of the foraminifera Cavarotalia annectens in the sediments collected by box core in the shelf region of Karwar, infront of the mouth of the Kalinadi river, India were used to map ... -
Forecasting of onset of southwest monsoon over Kerala coast using satellite data
(IEEE, 2004)The Global Precipitation and in situ gauge data have been used in the present study of the Indian monsoon for the region bounded by 8 to 13 degrees N; 70 degrees to 95 degrees E, from March 1 to May 31 for the years 1979 ... -
Impact of 1990-'95 ENSO/WEPO event on Indian monsoon rainfall
(NISCAIR, CSIR, 1997)The negative phase of the 1990-'95 El Nino-Southern Oscillation (ENSO) and the associated Warming of the Equatorial Pacific Ocean (WEPO) was the longest observed in the 113 years of its recorded history, compared to its ... -
Intra- and inter-seasonal variability of nutrients in a tropical monsoonal estuary (Zuari, India).
(Elsevier, 2014)A study was conducted to understand the intra- and inter-seasonal variability of dissolved oxygen and nutrients in a tropical monsoon estuary (Zuari in Goa, India). We adopted a dual sampling approach with (a) daily or ... -
Long range forecasting of summer monsoon rainfall from SST in the central equatorial Indian Ocean
(Indian Meteorological Society, 2001)Several prediction techniques have been developed to predict all India summer monsoon rainfall by using different parameters like sea level pressure tendency during January-April at Darwin, 500 mb location along 75 degrees ... -
Modulation of SST, SSS over northern Bay of Bengal on ISO time scale
(American Geophysical Union, 2011)High resolution observations of atmospheric and oceanic variables are carried out at northern Bay of Bengal from 22nd July to 6th August 2009 on-board ORV Sagar Kanya under the Continental Tropical Convergence Zone research/ ... -
Monsoon onset over Kerala and pre monsoon rainfall peak
(School of Naval Oceanology and Meteorology, India, 2004)In the present study the pentad Global Precipitation Climatology Project (GPCP) estimate have been used, which is a blended product of microwave, infrared and in-situ gauge data for the region bounded by 8 degrees - 13 ... -
Near-equatorial convective regimes over the Indian Ocean as revealed by synergistic analysis of satellite observations.
(World Scientific Publishing, 2010)We examine the organization and temporal evolution of deep convection in relation to the low level flow over the Indian Ocean by a synergistic analysis of several satellite datasets for wind, rainfall, Outgoing Longwave ... -
Observation-Based Estimates of Surface Cooling Inhibition by Heavy Rainfall under Tropical Cyclones
(American Meteorological Society, 2013)Tropical cyclones drive intense ocean vertical mixing that explains most of the surface cooling observed in their wake (the "cold wake"). The influence of cyclonic rainfall on the cold wake at a global scale over the 2002-09 ... -
On the role of surface heat budget parameters over the tropical Indian Ocean in relation to the summer monsoon
(IAPSO Commission for Vickbura Oceanogr. Co-Operation in Dev. Countries, 1996)This study presents the role of sea surface temperature (SST) in the Arabian Sea and Bay of Bengal, cloud motion vector winds in the Equatorial Indian Ocean, and the cold fronts in the South Africa-Malagassy region on the ... -
Over-estimation of sea level measurements arising from water density anomalies within tide-wells - A case study at Zuari Estuary, Goa
(The Coastal Education and Research Foundation, 2002)A 3-year study of water density anomalies within a conventional tide-well indicated that the average water density within the well was consistently lower than that of the external ambient waters. The tide-well at Marmugao, ... -
Predicting monsoon rainfall and pressure indices from sea surface temperature
