Abstract
Based on the direct numerical modeling results of irregular nonlinear waves on the surface of deep water within the framework of three-dimensional potential equations of hydrodynamics, the contributions of various wave components (second, third, and difference harmonics) to the formation of probability distributions of extreme wave heights, as well as the amplitudes of crests and troughs, are determined. The simulation results are analyzed taking into account four- and five-wave nonlinear interactions. Various nonlinear harmonics participate in the formation of probability distributions in a nontrivial way, which is essentially not amenable to the principles of linear addition and the contribution of ordering by a small nonlinearity parameter.
期刊介绍：
Izvestiya, Atmospheric and Oceanic Physics is a journal that publishes original scientific research and review articles on vital issues in the physics of the Earth’s atmosphere and hydrosphere and climate theory. The journal presents results of recent studies of physical processes in the atmosphere and ocean that control climate, weather, and their changes. These studies have possible practical applications. The journal also gives room to the discussion of results obtained in theoretical and experimental studies in various fields of oceanic and atmospheric physics, such as the dynamics of gas and water media, interaction of the atmosphere with the ocean and land surfaces, turbulence theory, heat balance and radiation processes, remote sensing and optics of both media, natural and man-induced climate changes, and the state of the atmosphere and ocean. The journal publishes papers on research techniques used in both media, current scientific information on domestic and foreign events in the physics of the atmosphere and ocean.
