Abstract
The Black Sea dynamics during 25 years is analysed using numerical simulation and assimilation of remote sensing data. Numerical circulation model has horizontal space resolution of 4.8 km and 40 vertical levels. It includes a turbulent model of the Mellor-Yamada type. Results of simulation were validated by comparing with temperature and salinity profiles from hydrological surveys. Analysis of the results shows that the temperature of the sea upper layer grows. Salinity of upper 30m layer also increases, but in the layer 30-100m it decreases. The results of simulation reproduce authentically circulation in the upper layer of the Black Sea. According to simulation, mean currents, directed opposite to the surface one, are observed at a depth of more than 400 m.
