The Effect of the Long-Term Variations in Climate Conditions on the Hydrological Structure and Ecology of the Black Sea

A scale of the atmospheric thermal conditions is elaborated, and the statistical distribution of the air temperature deviations from the norm is assessed. The cause of formation of the extreme atmospheric thermal conditions is found. Parameters of the winter hydrological structure are calculated, and their correlation with climatic conditions is shown. For the first time, the dynamic factor affecting the Black Sea hydrological structure is established, and its effect is shown.
