利用德州2006—2007年、2008年7月～2010年6月20时自动站和人工相对湿度观测数据,分析平均相对湿度对比差值的日、月、季节变化规律及影响差值大小的原因。结果表明：83.0%自动站日平均相对湿度值低于人工观测值,平均偏低2.07%,对比差值的标准差为1.79%;1日4次定时值中02时对比差值最大,14时最小;1～12月中,7～8月份对比差值最小,6月最大;四季中,对比差值冬季最大,夏季最小;相对湿度对比差值大小主要与相对湿度、温度大小和仪器的性能有关。

Using the observation data collected in 20pm.in the year of 2006-2007,July 2008 to June 2010 of Automatic Station and artificial relative humidity of Dezhou city,the regularity of average relative humidity comparison differential value of day,month and seasonal changes,as well as reasons of impact on difference was analyzed.The results showed that： 83.0% daily average relative humidity of automatic weather station was lower than that of artificial observation station with average at 2.07% lower,compared to the standard deviation of the difference 1.79%;Among the four times for timing,the maximum difference value in comparison was at 02am.and the minimum was 14pm.During the month of Jan.to Dec.,the maximum was in June and the minimum was in July and August.In the whole season,he maximum was in Winter and the minimum was in Summer.The comparison differential value was mainly related to the relative humidity,temperature and instrument＇s performance.
