Ecological Systems and Devices Annotation << Back ANALYSIS OF THE DATA OF LONG-TERM WAVE MEASUREMENTS NEAR SAKHALIN ISLAND A.V. Kokorina, A.V. Slunyaev, A.I. Zaytsev, E.G. Didenkulova, A.A. Moskvitin, I.I. Didenkulova, E.N. Pelinovsky Long-term measurements of bottom pressure variations obtained in 4 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 signifi cant 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 signifi cant 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. Keywords: in-situ data, data processing, rogue waves, probability distribution functions, statistical properties. DOI: 10.25791/esip.12.2022.1339 Pp. 045-054.
