POSSIBILITIES OF SATELLITE-ACQUIRED DATA ASSIMILATION IN THE GENERAL OCEAN CIRCULATION MODEL

A three-dimensional non-stationary primitive equation ocean model was constructed. The model includes free surface oscillations that permits the reproduction of ocean processes taking into account fast gravity waves (tides for example). The processes of the advection of heat and salt and the diffusion are described accurately. The model was tested by the simulation of the three-dimensional circulation of idealized and real basins. The inclusion in the model of the free surface oscillations on a level with physically more well- founded representation of oceanic processes permits the easy assimilation of the observed data including altimeter data. On the one hand the rationality consists of the possibility of the accurate testing of the model by comparisons of the large quantity of natural and computed information. On the other hand the coupling of the hydrodynamical model with a statistical block of data assimilation allows the solving of the problem of ocean fields diagnosis and forecasting on a higher level. It is hoped that more understanding will result of what types of observational data is needed and how it can be acquired in the ocean general circulation model with free surface.
