Meteorology and Hydrology, 2012 No 8. C. 6978. Using predictive fields of the driving wind and atmospheric pressure on the basis of a three-dimensional nonlinear model, the analysis of concurrency phenomena in the Sea of Azov. Comparison of the results of numerical calculations with the data of direct measurements of sea level at a number of coastal stations. The influence of changes in the intensity of atmospheric influences on the maximum values of deviations of the level and speed of currents, as well as on the peculiarities of impurity transformation. Analysis of the results of numerical calculations made it possible to draw conclusions about the dependence of the time of dispersion of pollution on wind speed and the location of pollution areas .
