Abstract
Hydrodynamic processes in the Black Sea for 2017 was modeled using real atmospheric data from the Skiron reanalysis model. Three-dimensional nonlinear σ-model of ocean circulation INMOM was used. The output data is compared with the observations of surface internal waves recorded in the coastal zone of the Southern coast of Crimea from Landsat-8, Sentinel-2 satellites in 2017. The variability of model temperature fields and current velocities in the area, where internal waves were identified in satellite imagery, was analyzed. A spectral analysis of level fluctuations of the Black Sea and the kinetic energy of currents on the Crimean shelf was carried out. The peculiarities of the barotropic regional dynamics of the tides K1, M2, reconstructed according to model data in the region under study, are revealed.
