HYDROMETEOROLOGICAL HAZARDS AND CASES OF THEIR SUPERPOSITION IN THE SEA OF AZOV FROM 1980 TO 2016 BY OBSERVATION DATA
On the basis of hydrometeorological data for coastal weather stations using hazard criteria of the Ministry of Emergencies, potential cases of adverse and dangerous situations of hydrometeorological phenomena in the Russian sector of the Sea of Azov from 1980 to 2016, including their combinations, are highlighted. The total sum is 112. Due to the small size and almost identical meteorological conditions on the entire eastern coast of the sea, stormy situations, including storm surges, cover the entire water area, and the spatio-temporal dynamics of different weather stations is similar. Most cases occur during the cold season. An interesting feature is that not all cases of dangerous hydrometeorological phenomena described in the literature that led to catastrophic consequences are identified on the basis of observational data. Cases of superposition of hydrometeorological hazards are mainly a combination of strong and very strong winds in effective directions, in which unfavorable and dangerous surges develop. Sometimes the phenomena are accompanied by heavy rains. Maximum cases of superposition of hydrometeorological hazards (9) - per decade 2000-2009. At the same time, the number of winter storm surges has been decreasing since 2000. Cases of extreme heat are noted only after 2000 and are typical only for August.
