Paper Abstract

This paper uses an original approach for the typification of synoptic situations from re-analysis data over a long period of time. This approach includes the typification of surface atmospheric pressure and surface wind velocity fields over the Azov-Black Sea basin. The results of typification (structures) of surface atmospheric pressure and surface velocity are presented in the form of Kohonen self-organizing maps (SOM), and the percentage of time recurrence of the allocated structures is given. The relevance of the study is due to the need to study the physical patterns of development of various types of intense atmospheric circulation over the Azov-Black Sea basin and their relationship with the largescale atmospheric circulation on multi-annual scales.
