Long-term measurements of bottom pressure variations obtained in four experimental campaigns near Sakhalin Island (Cape Svobodny) are analyzed. The statistical characteristics of 20-minute records of sea surface displacements reconstructed in the hydrostatic approximation, as well as individual wave parameters, such as wave height, period, and wave asymmetry, are studied. Records with similar meteorological conditions are sorted according to the significant wave height and the average wave period with the purpose to obtain statistically homogeneous data. The probability distributions of wave heights are constructed and compared with the Rayleigh and Glukhovsky distributions. A significant deviation from the theoretical curves in the range of anomalously high waves is demonstrated, which is associated with the records of intense wave groups in the winter season of 2014–2015.The research is supported by the Russian Science Foundation (Grant No. 22–17-00153). |
