Dynamics of large scale 3-dimensional circulation of the Indian Ocean
MetadataShow full item record
One of the main objective of this thesis is to adapt and configure a fully non-linear, primitive equation type, sigma co-ordinate 3-dimensional circulation model for the entire Indian Ocean area which can be run on diagnostic, semi-diagnostic and prognostic modes. Such a model could identify both the local and remote forcing of the Indian Ocean circulation. The other objectives of the thesis are the following: (i) To study the steady state 3-dimensional circulation of Indian Ocean based on semi-diagnostic calculation (ii) To simulate the climatic 3-dimensional circulation of Indian Ocean using the state of art sigma co-ordinate model. (iii) To study the sensitivity of Indian Ocean circulation to different wind fields (iv) To compare the model results with available information on currents and hydrography of Indian Ocean and to bring out the relative roles of local and remote forcing on the general circulation of Indian Ocean.

Near-surface circulation and kinetic energy in the tropical Indian Ocean derived from lagrangian drifters Shenoi, S.S.C.; Saji, P.K.; Almeida, A.M. (Yale University, 1999)Trajectories of 412 satellite-tracked drifting buoys deployed in the tropical Indian Ocean have been analyzed to document the surface circulation and kinetic energy field. Only drifters drogued at 15 m depth and having ...
Shaji, C.; Bahulayan, N.; Dube, S.K.; Rao, A.D. (John Wiley, 1999)A three-dimensional, fully non-linear semi-diagnostic (adaptation) model is described. This model is used to compute the climatological mean circulation and to understand the role of local, steady forcing of the wind and ...
