摘要
以青岛观象台的增、减水极值序列为例,探讨了异常增、减水极值序列的频率分析方法.用以分析的增、减水序列,分为不完整年极值序列和不完整过程极值序列.对以上两种序列,采用过程极值频率与年极值频率(或“重现次”与重现期)的转换关系,运用皮尔逊Ⅲ型曲线以及耿贝尔方法(第一型极值分布)进行了计算,获得理想的结果.此外,还对几种计算结果进行了比较分析.
According to the observational data of Qingdao Observatory during 1948-1979, the analytical methods of the probability distribution for the anomalous extremum sequence of set -up and set-down of storm surge are probed. The sequences were divided into two kinds: incomplete annual extremum sequence and the extremum sequence of the course. Through transition between the extremum sequence of the course and the annual extremum sequence, Pearson Type Ⅲ optimum Curve and Gumbel Method were used in calculation. The results show shat the adapting fitting by Pearson Type Ⅲ Curve is better than by Gumbel Method.
