摘要
暴雨强度公式的精度与资料的代表性有关,研究基于1983~2013年降雨资料,分析并推求出六盘水市新版暴雨强度公式。同时,新旧公式对比表明,两代公式差异显著,差率绝对值小于10%的比例仅为31.8%,大于30%的比例则占到25.0%。当降雨历时、重现期较小时,原公式暴雨强度计算值较小,反之则新公式计算值较小。
Base values affect the precision of storm intensity formula. Research based on the rainfall data of 1983-2013, derive a new storm intensity formula. Then the two formulas was put into comparison. Results showed the two formulas had significant difference, 31.8% values of calculated storm intensity had deviation less than 10 percent, while 25.0% values were more than 30 percent. When the rainfall duration, return period had low value, the calculated value of old formula was low and vice versa.
