气象要素极值的双指数分布函数求解

The Solution to Double Exponential Distribution Function of Meteorological Elements Extreme

利用安阳市 30年每年的日最大降水极值与双指数分布函数 ,求解出安阳市工程设计需要的设计频率(p)与气象要素极值 (降水Xp)的双指数分布函数关系式。用此函数关系式 ,可每年进行极值重新标定工作。

By using double exponential distribution function and annual max extremes of the recent 30 years' daily precipitation, we find the double exponential distribution functional relation between design frequency (p) and meteorology elements extreme (Xp), with which we can demarcate the extreme every year.
