Distribution of Surface Elevations in Nonlinear Seas

Abstract: The statistical distribution describing nonlinear narrowband waves characterized with second-order nonlinearities is simplified to an explicit closed form amenable to theoretical and practical applications. The approximate form and its salient features are examined and compared with oceanic measurements in deep and shallower water depths. The approximate form developed here provides certain advantages in terms its algebraic simplicity, accuracy and a somewhat wider domain of validity, in particular, relative t… Show more

“…In recent years, in the analysis and forecasting of the sea surface waves, second-order nonlinear models based on the wave profile decomposition in a series in powers of a junior parameter ε have become widespread [8,14,16,19]. In these models, elevation is represented as the sum of the linear and non-linear components.…”

“…Laboratory and field studies have shown that there are clear dependences of the sea surface elevations' cumulants on the steepness and the stage of the wave field development [6,17,18]. The existence of such dependences is confirmed by the modeling of nonlinear effects in the field of sea waves [4,19].…”

“…Исключение составил кумулянт четвертого порядка ( 4 λ ), для которого зависимость не была выявлена. Обсуждение В последние годы при анализе и прогнозе морских поверхностных волн широкое распространение получили нелинейные модели второго порядка, построенные на основе разложения волнового профиля в ряд по степеням малого параметра ε [8,14,16,20]. В рамках этих моделей возвышение представляют в виде суммы линейной и нелинейной составляющих.…”
