Abstract : The Black Sea is a nearly enclosed ocean basin, exhibiting many features common with larger ocean basins. Lacking an open boundary and having a limited exchange with sources of fresh and salt water, this basin is an ideal laboratory for developing and evaluating numerical circulation models. The present report describes one numerical models of the Black Sea, developed by Bulgarian and Russian scientists. The new approach has the advantages of both diagnostic models (incorporation of experimental data) and prognostic models (producing hydrodynamical adjustment and filtered fields). Successive application of diagnostic and prognostic models is used. The temperature and salinity fields obtained from observations, and currents obtained from diagnostic models, are used as the initial approximation to the prognostic model. Judicious selection of an integration time prevents over-smoothing of the results while preserving the stability of the solution.
