Abstract

Quasi-resonant four-wave interactions may influence the statistical properties of deep water surface gravity waves such as a freak wave. The freak wave prediction method developed by Mori and Janssen (2006) based on the quasi-resonant wave theory is compared with Europian Centre for Meidum Range Weather Forecasts wave analysis data. Mori and Janssen (2006) model shows low correlation with the observed wave data.To improve the forecasts score, the directional effects are considered by using a series of the Mote Carlo simulations of cubic Nonlinear Schrodinger equation. The broad band spectrum effects are also considered in the prediction method.
