波高与风速联合概率分布研究

基于copula函数论述了两变量的联合概率分布方法.此方法的主要优点是边缘分布可由不同的分布函数构成,变量间可具相关性.以粤东汕尾海域极值波高与相应风速为研究实例,经分析获得以下结果:(1)优选的极值波高和风速可分别由P-Ⅲ型和GEV 分布表示:(2)拟合优度检验指标表明二者的最优连接函数为Archimedean co...

Study on joint probability distribution of wave height and wind velocity

This article introduced the method of bivariate joint probability distribution based on the copula function.A major advantage of this method is that marginal distributions of individual variables can be of any form and the variables can be correlated.Some of conclusions were reached by using extreme wave height and wind speed as an example collected in Shanwei sea area as the following:(1) Optimized marginal distributions of wave height and wind velocity can be represented by the Pearson pattern three and g...
