Interannual variations of the renewal of waters of the cold intermediate layer in the Black Sea for the last decades

Experimental and Field Research

On the basis of the archival hydrological data, recently accumulated data of buoy profilometers, and the array of satellite data on sea-surface temperature, we estimate the interannual variability of the renewal of waters of the cold intermediate layer in the Black Sea for the last two decades. We propose a procedure of estimation of the intensity of renewal of waters for this layer according to the data on sea-surface temperature in the winter period without taking into account the vertical profiles of temperature. It is indicated that the last 50 yr are characterized by the alternation of periods with different intensities of ventilation of the upper layer of the sea. We analyze the correlations between the temperature of waters of the cold intermediate layer and the winter temperature of air (according to the data of meteorological stations located on the north coast of the Black Sea) and the level of salinity in the surface layer of the sea. The role played by the last factor is emphasized.
