ROGUE WAVES IN OCEANIC TURBULENCE

A stochastic model of wave groups is presented to explain the occurrence of exceptionally large ocean waves, usually referred to as rogue waves. The model leads to the description of the non-Gaussian statistics of oceanic turbulence (Zakharov 1999) and to a new asymptotic distribution of crest heights over large waves in a form that generalizes the Tayfun model (Tayfun 1986). The new model explains the unusually large crests observed in flume experiments of narrowband waves. However, comparisons with realistic oceanic measurements gathered in the North Sea during an intense storm indicate that the generalized Tayfun model do not appear to improve upon the Tayfun distribution.
