SPECTRAL CHARACTERISTICS OF CURRENTS AND TEMPERATURE OF SEA-WATER IN THE NEAR-BOTTOM LAYER ON THE BLACK-SEA SHELF OF RUSSIA

The oscillations spectrum of currents and water temperature in the nea r-bottom layer based on the data of longterm measurement on the Black Sea shelf is and analyzed. The main oscillations are generated by the Main Black Sea Current meanders, near-shore anticyclonic eddies, land and sea breeze, inertial motions, seiches and internal waves. The para meters of each form of oscillations are identified. The kinetic energy for the different time scales oscillations was estimated. The specifi c contributions of synoptic and mesoscale time variability were determ ined. The intensive wave oscillations of water temperature in the near -bottom layer were detected. It was identified, that these oscillation s are caused by it the propagation of the near-shore anticyclonic eddi es. A qualitative mechanism of these oscillations is studied.
