摘要
本文根据暴雨强度资料,采用皮尔逊Ⅲ分布模式对暴雨强度频率分布进行拟合,并由此编制反映暴雨强度、历时、重现期三者关系的i—t—T表。在对暴雨强度公式中参数确定时,引入基于非线性最小二乘法原理的数学优化技术,并给出了在Matlab环境下的实现过程。
i-t-T table which reflect the storm intensity, duration and reproduce was given according intensity data and using P-Ⅲ distribution patterns to fit the frequency distribution of storm intensity. mathematical principles based on the nonlinear least squares of storm intensity and it was achieved in Matlab storm The method were introduced as determining the parameters of storm intensity and it was achieved in Matlab
