551.465On the basis of the analysis of the archival data, we reveal some regularities of the interannual and seasonal variations of the parameters of atmospheric transport, winds, air temperature, the amount of atmospheric precipitation in the Kerch region, the temperature of water in the Kerch Strait, and the water discharge through the strait observed for about the last two decades. It is shown that the intensities of the southeast atmospheric transport and wind activity predominant for the previous 30-yr period decreased for the analyzed time period as compared with the previous period, whereas the amount of atmospheric precipitation and the annual average temperatures of water in the strait and air in the Kerch region increased. We also reveal the presence of direct qualitative relationship between the intensity of atmospheric transport over the Kerch Strait and the water discharge in its water area.The water area of the Kerch Strait and the parts of the seas neighboring with this area are regarded as especially ecologically unfavorable regions of the Azov-Black-Sea basin. The powerful anthropogenic influence permanently increasing in this region strongly affects numerous important components of the ecosystem of the strait, such as the system of currents, water exchange, vertical stratification of waters, ice conditions, hypoxia, migration of commercial fishes, and their mass death. The above-mentioned problems and various aspects of these problems are now discussed in numerous works (see, e.g., [1][2][3][4][5][6]).The problems analyzed in the present work deal with poorly studied components of the ecological complex of the Kerch region. Thus, we consider the current state and time dependences of the principal meteorological elements of the region, as well as the temperature of water and its discharge through the Kerch Strait.Note that regular instrumental measurements of currents in the Kerch Strait aimed at the evaluation of the water discharge through its northern narrow neck are not performed for the last two decades. The absence of any data about the discharge and the impossibility of its direct evaluation at present make the solution of various practical and scientific problems quite complicated. In this connection, we make attempt to reveal the relationship between the water discharge through the Kerch Strait and the atmospheric transport over its water area. Material and MethodAt the beginning of the 1990s, the following significant changes were recorded in the interannual course and seasonal variations of the hydrometeorological characteristics of the analyzed region (note that these changes were not recorded earlier): the intensity of the predominant southeast atmospheric transport and wind activity decreased, the amount of precipitation increased, the annual average temperatures of water in the strait
