利用乌鲁木齐地区2004—2008年自动与人工站观测降雨量数据,分析了观测数据的差异以及产生差异的原因,并分析了自动观测与人工观测降雨量的相关性。结果表明：64.7%的自动站观测降雨量数据高于人工观测数据,对比差值范围在-3.2～1 mm之间,平均差值为-0.29 mm;对比差值的频率分布呈偏正态,分布曲线较陡,差值分布较集中;对比数据的粗差率、一致率分别为5.9%、90.1%,降雨量百分误差在±4%以内的占89%,误差百分率为11.0%;两种观测结果呈线性正相关,相关系数为0.999。观测数据产生差值是多方面因素综合影响的结果。

Based on rainfall data observed automatically and manually in Urumqi during the 2004-2008,this article analyzed the observation difference and its reason,and discussed the correlation between the two ways.The results showed that 64.7% rainfall data observed automatically were higher than that by manual observation;and the difference ranged from-3.2 to 1mm with an average of-0.29 mm;the frequency distribution of difference value showed the partial normal distribution with steeper distribution curve,and the differences were rather concentrated;the coarse difference rate and consistent rate of comparison data were 5.88% and 90.1% respectively,and rainfall percentage error within ± 4% was 89% in all data,the error percentage of observation data reached 11.0%;the correlation coefficient of the two observation data was 0.999 with obvious linear correlation.The difference value of observational data was generated by combined effects of various factors.
