| Abstract: | We realize the algorithm of adaptive statistics of forecasting errors for the assimilation of the climatic fields of temperature
and salinity in the σ-coordinate model of the dynamics of the Black Sea. The principal relations of this algorithm and its
simplified version based on the Kalman filter are presented. The distinctive features of realization of the algorithm specified
by the model are discussed. We also present the results of comparison of the hydrophysical fields of the Black Sea reconstructed
according to the algorithm of adaptive statistics and a simplified scheme of assimilation of the climatic data. It is shown
that the dependence of sources in the transport equations (heat and salt diffusion) on the four-dimensional variances of forecasting
errors and threedimensional measurement errors enables one to reconstruct the mutually adapted climatic parameters of the
sea more exactly. |
