Changes in the recurrence of extreme wind waves in the World Ocean are connected with the global climate change. The end of the 20th and the beginning of the 21st centuries are characterized by significant climate warming, the reduction of the Arctic sea ice and changes in the recurrence of various extreme meteorological events. The main motivation of this research is to assess the trends of storm recurrence for the time period from 1979 up to 2020 and to analyze the connection between storminess and large-scale atmospheric circulation indexes. This research contains information about the number of storms that occurred in seven Russian Seas, including the Black, Caspian, Barents, Kara, Bering Seas, the Sea of Okhotsk and the Sea of Japan/East Sea. These seas are located in different climate conditions determined by the Atlantic, Pacific and Arctic oceans. The analysis of wave climate and storm activity is based on the results of wave modelling by WAVEWATCH III with input NCEP/CFSR wind and ice data. The mean plots, maximum, and 95% percentile sig-nificant wave heights are also presented in the research. Significant linear uptrends in the number of storms were found in the Kara, Caspian, Bering, Okhotsk Seas, and in the Sea of Japan. The relationship between the inter-annual variability of the number of storms and large-scale at-mospheric indexes is considered.

“…Lyubitskiy et al [2021] described a marine hazard in the Sea of Okhotsk. Lopatoukhin et al [2009] showed the possible 9.9 m SWH can occur in the East/Japan Sea (EJS) once for 25 year. In winter, winds are strong due to the east Asian monsoon, while blowing mild or moderate and variable in summer [Lee et al, 2010].…”

The article presents the results of adaptation of the MIKE 21 Flow Model FM hydrodynamic module of the MIKE Zero software package to the Caspian Sea region using reanalysis data of wind and pressure fields, both for individual years and for a long-term period (2000–2020). The quality of modeling results was assessed using the statistical methods. The correlation coefficient between observed and simulated water levels for the period of 2000–2020 was 0,97 for Fort Shevchenko and 0,95 for Aktau. Model calibration allowed obtaining optimal values of model parameters, such as the Smagorinsky turbulent viscosity coefficient of 0,5 and the Manning roughness coefficient of 0,031. The evaluation for the multi-year period and the individual cases demonstrated that the modeling quality criteria were within acceptable limits. The results of the model verification based on the data for 2000–2020 and its testing for the storm surge on March 5–7, 2022, indicated that in the future the MIKE Zero software package could be used for operational sea level forecasting.
