Variability Peculiarities of Distribution of Transparency and Suspended Matter Content in the Northwestern Part of the Black Sea in Spring Caused by Large-scale Processes in the Ocean–Atmosphere System

The display is considered of global processes in the ocean–atmosphere system in the variability of hydrophysical and hydrobiological fields of the northwestern part of the Black Sea in spring period of 1978–1995. It is demonstrated that the variability of North Atlantic and Southern oscillations in winter-spring period affects the spring hydrometeorological conditions in catchment areas of European rivers of the Black Sea basin causing the variability of runoff volumes of these rivers and the scales of spreading river waters at the northwestern shelf. Hydrological and hydrobiological characteristics of shelf waters varying in the process influence the formation of distribution of suspended matter content and transparency.
