| 摘 要： | 为了检验天气发生器CLIGEN在华北地区生成降水的有效性,应用该区15个气象站1951-2008年的日气象观测资料和CLIGEN生成的150a日气象数据,对CLIGEN再现该区降水的效能进行了评估。结果表明:CLIGEN很好地再现了年和日降水量的均值和降水日数,但对降水极值的模拟精度不高,年和日最大降水量的平均相对偏差均大于均值的平均相对偏差。非参数检验的结果表明,CLIGEN能很好地生成年降水量的概率分布,且对日降水的概率分布也有较高的生成精度。总体来看,CLIGEN模型在华北地区能很好地再现年、日降水量平均值统计特征,并较好地再现了降水的变率。

| Abstract: | To determine the efficiency of precipitation generated by CLIGEN in North China,precipitation records from 15 weather stations from 1951 to 2008 in North China and 150 years of CLIGEN generated data were used to evaluate the CLIGEN weather generator. Results showed that the means of annual and daily precipitation amount and days of precipitation were all well generated by CLIGEN,whereas extremes of precipitation were not adequately preserved. Mean Absolute Relative Errors (MARE)of annual and daily maximum p... |
