中文摘要：
选取上海市崇明岛侯家镇气象站纪录的47个台风最大10min时距平均风速和最大雨强作为样本,使用不同的概率分布模型分别对风速和雨强的概率分布参数进行拟合并作拟合优度比较,提出台风条件下风速和雨强联合概率分布函数。优化结果表明,Gumbel Copula函数联合概率分布模型和极值Ⅰ型联合概率分布模型适合描述台风条件下风速和雨强联合概率分布,其中Gumbel Copula函数联合概率分布模型中风速和雨强各自的概率分布模型分别采用极值Ⅲ型概率分布模型和Gamma分布模型。
英文摘要：
47 measured data of typhoon wind speed and rainfall intensity of Chongming Island Houjia weather station in Shanghai are taken as the data samples.The probability distribution models of wind speed and rainfall intensity are carried out and fitting results are compared respectively.Wind speed and rainfall intensity joint probability distribution models are constructed in typhoon condition.The result shows that wind speed and rainfall intensity joint probability distribution can be described by Gumbel Copula function and extreme value type Ⅰ joint probability distribution model preferably,and Gumbel Copula function consist of extreme value type Ⅲ joint probability distribution model for wind speed and Gamma distribution model for rainfall intensity.
