Structure and long-term dynamics of surface atmosphere of Azov- Black Sea region on the base of self-organizing map analysis

摘要

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