The paper considers cases of sharp short-term increases in the Black Sea level in the region of the Southern coast of Crimea caused by wind surges, using the example of 2014–2016. It was shown that almost all cases of abnormal sea level rise in the coastal zone during the study period were the result of exposure to wind surges. Based on altimetry data and data on the wind speed of the MERRA reanalysis, parametrization is proposed for calculating changes in the coastal level at intervals of up to 10 days. The proposed parametrization, which quadratically depends on wind speed, describes the high-frequency fluctuations in sea level quite well and can be used for prognostic purposes. A lesser effect of wind on sea level was noted during the formation and existence of a seasonal thermocline before the beginning of winter convection, apparently due to the action of friction stress in a less deep layer. The change in the level with driving winds is insignificant. © 2020 Space Research Institute of the Russian Academy of Sciences. All rights reserved.
