Anomalous circulation in the eastern equatorial Indian Ocean during southwest monsoon of 1994
(NIO, Dona Paula, Goa (India), 2000)Geostrophic circulation derived from hydrographic data collected during July-August, 1994 along 80, 84 and 88E between 5N and 3S latitudinal belt in the eastern equatorial Indian Ocean is presented. A broad westward flow ... -
BOBMEX: The Bay of Bengal Monsoon Experiment
(American Meteorological Society, 2001)The first observational experiment under the Indian Climate Research Programme, called the Bay of Bengal Monsoon Experiment (BOBMEX), was carried out during July-August 1999. BOBMEX was aimed at measurements of important ... -
Circulation and Distribution of some Hydrographical Properties during the late Winter in the Bay of Bengal
(Indian Association for Limnology and Oceanography, 1981)Charts showing dynamic topography, mass distribution, temperature, salinity, dissolved oxygen and inorganic phosphate in the upper layers of the Bay of Bengal for the late winter period were analysed and presented. The ... -
Estimation of eddy diffusivity coefficient of heat in the upper layers of equatorial Arabian Sea
(NISCAIR, CSIR, 1995)A 1-D model for estimating eddy diffusivity coefficient of heat (K sub(h)) in the upper layers of the sea is proposed and tested using data collected along 68 degrees E and 52 degrees in the equatorial Arabian Sea. Diurnal ... -
Flow field in the inner shelf along the central east coast of India during the southwest monsoon season
(Coastal Education and Research Foundation, 2004)Current measurements collected along the inner shelf off the central east coast of India at seven stations during August-September 1988 are discussed. Data indicate a southerly flowing alongshore current, which occupies ... -
Impact of temperature inversions on SST evolution in the South-Eastern Arabian Sea during the pre-summer monsoon season
(American Geophysical Union, 2004)Temperature inversions are known to occur in the near-surface ocean regime where salinity stratification is large enough to influence the density field. However, they have not been known as features that alter near-surface ... -
Influence of upper-ocean stratification on tropical cyclone-induced surface cooling in the Bay of Bengal
(American Geophysical Union, 2012)Surface cooling induced by tropical cyclones (TCs) is about three times larger during premonsoon than during postmonsoon season in the Bay of Bengal. We investigate processes responsible for this seasonal contrast using ... -
Observations of barrier layer formation in the Bay of Bengal during summer monsoon
(American Geophysical Union, 2002)Time series of temperature and salinity in the upper ocean, measured at 17 degrees 30'N, 89 degrees E in the northern Bay of Bengal, from 27 July to 6 August 1999 captured an event of upper layer freshening. Initially, the ... -
On the accuracy of the simple ocean data assimilation analysis for estimating heat Budgets of the Near-Surface Arabian Sea and Bay of Bengal
(American Meteorological Society, 2005)The accuracy of data from the Simple Ocean Data Assimilation (SODA) model for estimating the heat budget of the upper ocean is tested in the Arabian Sea and the Bay of Bengal. SODA is able to reproduce the changes in heat ... -
Response of the equatorial Pacific to chlorophyll pigment in a mixed layer isopycnal ocean general circulation model
(American Geophysical Union, 2001)The influence of phytoplankton on the upper ocean dynamics and thermodynamics in the equatorial Pacific is investigated using an isopycnal ocean general circulation model (OPYC) coupled with a mixed layer model and remotely ... -
Salinity maxima associated with some sub-surface water masses in the upper layers of the Bay of Bengal
(National Institute of Sciences of India, 1968)The distribution of some sub-surface water masses in the western bay of Bengal during the south-west monsoon period is presented. Based on the salinity maxima and sigma t values the existence of waters of Persian Gulf and ... -
Seasonal cyclogenesis and the role of near-surface stratified layer in the Bay of Bengal
(NIO, Dona Paula, Goa (India), 2000)The role of the near-surface stratified layer developed due to the spread of low salinity waters under the influence of freshwater influx on the cyclogenesis over the Bay of Bengal is addressed. The seasonal variation of ... -
Some aspects of nutrient chemistry of the Caribbean Sea
(Institute of Marine Affairs, 1991)Chemical oceanographic studies were conducted at 45 stations in the Caribbean Sea, covering both nearshore and offshore areas. The concentrations of oxygen in the upper mixed layers varied between 180 and 220 mu mol.dm ... -
The Lowering of Sea Surface Temperature in the East Central Arabian Sea Associated with a Cyclone
(Indian Association for Limnology and Oceanography, 1983)An analysis of thermal Structure in the East Central Arabian Sea associated with a moderate cyclone is presented. The heat storage and the heat budget components have been computed. Under the influence of the cyclone the ... -
Thermal response of upper layers of Bay of Bengal to forcing of a severe cyclonic storm: A case study
(NISCAIR, New Delhi, 1993)Upper ocean response to forcing of a severe cyclonic storm during May 1990 in the western Bay of Bengal was studied using the XBT data sets collected (4 d after passage of storm) under Indian TOGA programme. A maximum ... -
Upper ocean circulation modulation by phytoplankton concentration in the Equatorial Pacific and the Indian Ocean
(PORSEC 2002 Secretariat; Bogor; Indonesia, 2002)Wind patterns in the equatorial Pacific and Indian oceans are the factors that regulate the chlorophyll pigment distributions in the equatorial region of these oceans. Trade winds and coastline of the Pacific basin supports ... -
Upper ocean variability in the Bay of Bengal during the tropical cyclones Nargis and Laila
(Elsevier, 2012)Upper ocean variability at different stages in the evolution of the tropical cyclones Nargis and Laila is evaluated over the Bay of Bengal (BoB) during May 2008 and May 2010 respectively. Nargis initially developed on 24 ... -
