Abstract
The data of numerical simulation of thermohaline structure and water dynamics in the north-eastern Black Sea is compared with data of satellite and contact observations at marine meteorological stations of the Caucasus Coast. It was shown that the modeling sea surface temperature have very high similarity and correlation with the observational data (more than 93 %) due to the assimilation of satellite data in the Black Sea model, the data from which are the initial and boundary conditions for the regional model. The correlation coefficients of satellite altimetry data, meteorological stations and modelling exceed 70 %. This result shows that the altimetry and modeling data to track and forecast the level should use, also these data may be used in their assimilation algorithms in numerical models. Moreover, it is necessary to modify the altimetry data assimilation algorithms used in operational oceanography to adjust the simulated salinity in shallow sea.
