Abstract

Abstract

A typical double-peaked wave spectrum data,collected at the A merican National Data Buoy 44008 from June,2002.Using WAFO (Wave A nalysis for Fatigue and Oceanog raphy) method,it represents the latest developments.Taking the measured spectrum as the target spectrum,fast and exact simulate stationary Gaussian process through circulate embedding of the Covariance matrix.We find the estimate spectrum is very closing the measured spectrum,and peak frequency almost same.It is a feasible method based on simulated wave surface,which can reflect the wave charact eristics.Using observed wave spectrum data,we analyze sea wave characteristics.We can sea that the theoretical density and the estimated density are in good agreement with the original spectrum.Using Longuet-Higgins(1983) model,we calculate joint pdf of crest height and crest period.We conclude that joint probability density function of crest height and crest period calculated on the transform Gaussian sea is very closing the joint pdf of crest height and crest period derived by the measured data.
