Seasonal Variation of Diurnal Cycle of Rainfall in the Eastern Equatorial Indian Ocean
RameshKumar, M.R.; Pednekar, S.; Katsumata, M.; Antony, M.K.; Kuroda, Y.; Unnikrishnan, A.S. (SpringerLink, 2006)The diurnal cycle of rainfall over the eastern equatorial Indian Ocean is studied for the period 23rd October 2001 to 31st October 2003 using the hourly data from the Triton buoy positioned at 1.5°S and 90°E. An analysis ... -

Signatures of Kelvin and Rossby wave propagation in the northern Indian Ocean from TOPEX/POSEIDON Altimeter
PrasannaKumar, S.; Unnikrishnan, A.S.; Muraleedharan, P.M. (NIO, Dona Paula, Goa (India), 2000)The climatological monthly mean sea surface height (SSH) anomalies derived from T/P altimeter in the northern Indian Ocean, during 1993 to 1997, are used to prepare time-longitude plots. Along the equator they reveal strong ... -
Simulation of barotropic wind-driven circulation in tbe Bay of Bengal and Andaman Sea during premonsoon and postmonsoon seasons
Unnikrishnan, A.S.; Bahulayan, N. (NISCAIR, New Delhi, 1991)Two-dimensional vertically integrated model has been used to simulate depth-mean wind-driven circulation during premonsoon and postmonsoon seasons in the upper layers of the Bay of Bengal and Andaman Sea. The model is ... -
Simulation of barotropic wind-driven circulation in the upper layers of Bay of Bengal and Andaman Sea during the southwest and northeast monsoon seasons using observed winds
Bahulayan, N.; Unnikrishnan, A.S. (Indian Academy of Sciences, 1992)A two-dimensional, nonlinear, vertically integrated model was used to simulate depth-mean wind-driven circulation in the upper Ekman layers of the Bay of Bengal and Andaman Sea. The model resolution was one third of a ... -
The monsoon currents in the north Indian Ocean
Shankar, D.; Vinayachandran, P.N.; Unnikrishnan, A.S. (Pergamon (Elsevier), 2002)The monsoon currents are the seasonally reversing, open-ocean currents that flow between the Arabian Sea and the Bay of Bengal, the two wings of the north Indian Ocean. The Summer Monsoon Current (SMC) flows eastward ... -
Tidal asymmetry in the Mandovi and Zuari estuaries, the West Coast of India
Manoj, N.T.; Unnikrishnan, A.S.; Sundar, D. (Coastal Education and Reserch Foundation, 2009)Harmonic analysis of the observed and simulated tides in the Mandovi and Zuari estuaries along the west coast of India was carried out. Tidal constituents derived from this process were analyzed to study the tidal asymmetry ... -
Tidal circulation and salinity distribution in the Mandovi and Zuari estuaries: Case study
Manoj, N.T.; Unnikrishnan, A.S. (American Society of Civil Engineers, 2009)The Mandovi and Zuari are two tropical estuaries along the west coast of India, characterized by mixed tides with semidiurnal dominance and heavy fresh water influx during the southwest monsoon (June to September). Previous ... -
Tidal propagation in the Gulf of Khambhat, Bombay High, and surrounding areas
Unnikrishnan, A.S.; Shetye, S.R.; Michael, G.S. (Indian Academy of Sciences, Bangalore, India, 1999)The continental shelf on the west coast of India is widest off Bombay and leads into a strongly converging channel, the Gulf of Khambhat. Tides in the Gulf are among the largest on the coast. Data on amplitude and phase ... -
Tidal propagation in the Mandovi-Zuari Estuarine network, west coast of India: Impact of freshwater influx
Unnikrishnan, A.S.; Shetye, S.R.; Gouveia, A.D. (Academic Press, 1997)The Mandovi-Zuari estuarine network on the west coast of India consists of shallow strongly converging channels, that receive large seasonal influx of fresh water due to the monsoons. The main channels, the Mandovi and ... -
Tidal propagation off the central west coast of India
Unnikrishnan, A.S. (NISCAIR, CSIR, 2011)Present study reviews the characteristics of tidal propagation on the continental shelf off the central west coast of India. Available observations from tide gauges are used to describe the variations of tidal ranges along ... -
Tidal regime in Gulf of Kutch, west coast of India, by 2D model
Unnikrishnan, A.S.; Gouveia, A.D.; Vethamony, P. (American Society of Civil Engineers, 1999)A 2D barotropic numerical model is developed for the Gulf of Kutch with a view to synthesize available information on tides and currents in the Gulf. A comparison of model results with moored current meter observations ... -
Tide gauge data analysis of sea-level rise trends along the coastal zone of the North Indian Ocean

Tide Gauges
Unnikrishnan, A.S.; Mathews, A.; Gravelle, M.; Testut, L.; Thorkild, A.; Woodworth, P.L.; AjayKumar, B. (CLIVAR/IOC-GOOS Indian Ocean Region Panel (IORP), 2019)Tide gauge measurements provide data for routine tidal predictions in ports as well as for extreme events such as storm surges and tsunamis. Along with satellite altimeter measurements, tide gauges also provide measurements ... -

Tide-surge interaction at the head of the Bay of Bengal during Cyclone Aila
Antony, C.; Unnikrishnan, A.S.; Krien, Y.; Murty, P.L.N.; Samiksha, S.V.; Islam, A.K.M.S. (Elsevier B.V., 2020)Tide-surge interaction serves a critical role in shallow coastal regions in modifying the characteristics of peak water levels during storm events. In the present study, we investigated the tide-surge interaction in the ... -
