对深海陡波和高波发生概率的估计

ESTIMATION FOR PROBABILITIES OF OCCURRENCE OF STEEP AND HIGH WAVES IN DEEP WATER

本篇引入三个描述非对称波的参数,即峰前陡度、垂直不对称因子以及水平不对称因子。它们是由Myrhaug和Kjeldsen首先建立的,利用信息函数获得峰前陡度和波高之间的相关度。对峰前陡度与高度的联合概率密度分布的两种模式,给出JONSWAP谱的陡波和高波发生概率的估计。

In this paper three aew parameters describing asymmetric wave are cited, they are the crest front steepness, vertical asymmetry factor and horizontal asymmetry factor created by Myrhaug and Kjeldsen. Using the information function the correlation degree between the crest front steepness and the wave height is got. The probabilities of occurrence of steep and high waves describe dby a JONSWAP spectrum are estimated using two models on joint probability density distribution of the crest front steepness and height,
