| Zusammenfassung |
| This work studies the impact of wind on extreme wave events, by
means of numerical analysis. A High Order Spectral Method (HOSM) is
used to generate freak, or rogue waves, on the basis of modulational
instability. Wave fields considered here are chosen to be unstable
to two kinds of perturbations. The evolution of components during
the propagation of the wave fields is presented. Their evolution
under the action of wind, modeled through Jeffreys' sheltering
mechanism, is investigated and compared to the results without wind.
It is found that wind sustains rogue waves. The perturbation most
influenced by wind is not necessarily the most unstable. |
