“…The northern part of the Main Caucasian Ridge is an important climate-forming factor that controls the land-sea exchange of air masses. An extreme manifestation of the complex air circulation system in this area is known as the Novorossiysk bora [18]. During these events, local winds can exceed 40 m/s with wind gusts up to 100 m/s [41].…”

Wave buoy measurements were carried out near the north-eastern Black Sea coast at the natural reserve Utrish in 2020-2021. Totally about 11 months of data records were collected during two stages of the experiment at 600 and 1500 meters offshore and depths of 18 and 42 meters. The measured waves propagate almost exclusively from the seaward directions. Generally, the waves do not follow the local wind directions, thus, implying a mixed sea state. Nevertheless, dependencies of dimensionless wave heights on periods based on the wind speed scaling appear to be close to previously established empirical laws for the wind-driven seas. The results of the wave turbulence theory are applied for estimates of spectral energy fluxes and their correspondence to the energy flux from the turbulent wind pulsations. These estimates are consistent with today’s understanding of wind-wave interaction. It is shown that the main fraction of the wind energy flux goes to the direct Kolmogorov-Zakharov cascade to high wave frequencies and then to dissipation in small scales. Less than 1% of the wind energy flux is directed to low frequency band (the so-called inverse Kolmogorov-Zakharov cascade), thus, providing wave energy growth.

Topicality. Climate change in the Black Sea region in recent decades poses certain risks to the econo-mies of countries of region, and may have a significant negative impact on the state of terrestrial and marine ecosystems. The main areas of economic activity in the Black Sea are maritime freight, oil and gas production and transportation, industrial extraction of marine biological resources, recreational and tourist activities in coastal areas, etc. The Black Sea significantly affects the climate of the south-eastern part of the European continent, forming regional climatic features in the area. The development of measures to adapt to climate change requires the collection and analysis of data on the state of the climate system and the current characteristics of their interaction and feedback. Purpose. The purpose of this work is to review and analyze information on regional climate change observed in recent decades to find patterns and possible links with the variability of the hydrological regime of the Black Sea. Results. This paper contains information on the main climatic characteristics of the Black Sea region, such as air temperature, precipitation, atmospheric pressure, wind speed, as well as indicators of cyclonic activity. Conclusions. In recent decades, the Black Sea region has seen an increase in air temperature caused by changes in large-scale atmospheric circulation, in the form of increased recurrence of anticyclonic processes, leading to a decrease in clouds and an increase in shortwave radiation entering the underlying surface. At the same time, since the mid-2000s, the increase in average annual air temperature has increased. The average annual rainfall is maintained in most parts of the region, with the exception of the eastern part of the Black Sea coast of Turkey and the coastal areas of Georgia, where there is an increase in both rainfall and the frequency of extreme rainfall. At the same time, there is some increase in both the intensity and amount of winter precipitation over the Black Sea. Wind speeds in the Black Sea region as a whole show a decrease in their values, with some increase in the western part of the Black Sea, which is also associated with changes in the peculiarities of circulating processes that develop over South-Eastern Europe.
