Localized Coherence of Freak Waves
Abstract. This paper investigates in detail a possible mechanism of energy convergence leading to freak waves. We give examples of a freak wave as a (weak) pseudo-maximal wave to illustrate the importance of phase coherence. Given a time signal at a certain position, we identify parts of the time signal with successive high amplitudes, so-called group events, that may lead to a freak wave using...
متن کاملA Discrete Wavelet Analysis of Freak Waves in the Ocean
In the past few years, wavelet methods have been applied in coastal and ocean current data analysis [2, 5, 6]. These new tools have better performance than the traditional Fourier techniques. They localize the information in the time-frequency space and are capable of trading one type of resolution for the other, which renders them suitable for the analysis of nonstationary signals. It was firs...

15 صفحه اولNonlinear four-wave interaction and freak waves
Four-wave interactions play an important role in the evolution of the spectrum of surface gravity waves. This follows from direct simulations of an ensemble of ocean waves using the Zakharov equation. The theory of homogeneous four-wave interactions, extended to include effects of nonresonant transfer, compares favourably with the ensemble averaged results of the Monte Carlo simulations. In par...
متن کاملAuthor’s Response Localized Coherence of Freak Waves
We thank the anonymous referee #1 for the positive and constructive remarks. Just like the referee, we struggled to improve and simplify the presentation of the technical results. In section 2 we tried to illustrate in a simple way the role of coherence by considering the (weak) pseudomaximal signals. Then, to justify the use of the wavelet transform, we showed how the coherence of phase inform...
