Use of satellite observation in ocean general circulation model for understanding regional circulation and heat budget in the Indian Ocean

  1. Assimilation of satellite derived temp, salinity and sealevel is needed to improve the accuracy ocean model simulations of temp, salinity and currents and their vertical profiles.
  2. Altimeters routinely provide information regarding sealevel, wind and wave information.
  3. IR and Microwave radiometers provide SST information which can be assimilated in ocean circulation model for understanding regional circulation and heat budget in the Indian Ocean.
  4. Altimeter derived sealevel can be assimilated using variational techniques such as 3D var and 4D var in ocean circulation models such as MOM, ROMS, MITGCM etc. 5. Altimeter derived significant wave height can be assimilated in ocean wave models such as SWAN, WAVEWATCH etc., for improved prediction of waves along the Indian coasts.

Development of eddy-resolving meso scale ocean model and potential fishing zone predictability

Ocean eddies are important features, which play a dominant role in ocean dynamics, nutrient transportation and modification of circulation patterns. The satellite observations have revealed their distribution and temporal variability. Modelling such eddies is underway using a Regional Ocean Modelling System (ROMS). The model has been set up and integrated with Winds, Temperature, Salinity and Surface heat fluxes data for simulation of eddies and regional circulation in the Indian Ocean
