Abstract. The paper discusses extreme precipitation recorded at 12 meteorological stations on the Eastern Coast of the Black Sea according to reanalysis data and at three stations according to their observations. Comparison of observational data with reanalysis data is carried out. The relationship between extreme precipitations at each station and elementary circulation mechanisms (ECMs) according to typification developed by B.L. Dzerdzeevsky, V.M. Kurganskaya, and Z.M. Vitvitskaya has been analysed. ECMs was revealed, at which precipitation extremes were noted simultaneously at several stations. It has been established at which ECMs on the Eastern coast of the Black Sea extreme precipitation most often occurs, and long-term changes in the duration of these ECMs are analysed.
Keywords: elementary circulation mechanism, extreme precipitation, Eastern Coast of the Black Sea.
