The interannual variability of the types of synoptic situations is investigated. The re-analysis sea surface atmospheric pressure is analyzed for 1979-2017 for the Azov-Black Sea region with the aim to recognize the variability of the surface atmosphere dynamics. The results of surface atmospheric pressure typing are presented in the form of Kohonen self-organizing maps, and the percentage of time recurrence of the selected structures is given. The relationship between the features of the atmospheric circulation over the region and the intensity of sea level fluctuations on seasonal and interannual scales are analyzed. The relevance of the study is determined by the need to study the physical patterns of development of various types of intensive atmospheric circulation over the Azov-Black Sea basin, their features of inter-annual variability, and the relationship with large-scale atmospheric circulation on a multi-year scale. The results are used to establish the influence of atmospheric circulation on the repeatability of the storm surges in the Azov-Black Sea region on the seasonal and interannual scales.
