摘要
文章探讨了特大值的判定方法及其对暴雨强度公式计算精度的影响。根据呼和浩特市1954—2013年各历时降雨实测数据,对特大值进行了检验,并采用不同方法进行处理,将所得结果进行对比分析。结果表明:如果不对特大值进行处理,将达不到规范要求的计算精度,而经过特大值处理后,计算精度明显提高,从而得到了更合理的暴雨强度公式。
In this paper, judgment method of extraordinary big value and its impacts on calculation accuracy of rainstorm intensity formula were discussed. Based on the real precipitation data from 1954 to 2013, extraordinary big values were tested and processed by different methods in order to contrast the results. The results showed that calculation precision wasn＇t reached with the request of Code. When the extraordinary big values were processed, the calculation precision was improved obviously,it get more reasonable rainstorm intensity formula.
