Abstract
If the sea is narrowband, the Rayleigh distribution introduced by Longuet-Higgins can be used for the individual wave height distribution. However, the Rayleigh distribution often over-predicts the probability of high waves. Longuet-Higgins introduced an alternative form of the Rayleigh distribution with an empirical constant. The wave height distribution can be fitted well by one parameter Rayleigh distribution with a proper choice of the empirical constant. In this paper, the empirical constant is determined by a ratio of the significant wave height, bused on the time domain analysis and the spectral analysis. Here we examine wave data that contain extreme waves. The empirical constant in the modified Rayleigh distribution is determined simply by a ratio of significant wave heights, based on the time-domain method and wave spectrum. We confirmed that extreme wave height distribution can be modeled well by a modified Rayleigh distribution.1. 서 론
