中文摘要: 应用石家庄2001年5月～2002年3月城区自动站和2003年1～5月CAWS600自动站的观测资料,分别与同步的常规人工站观测资料对比分析。从它们感应器件和测值原理的不同、观测时间的差异、天气条件的影响等方面,分析了观测记录差异形成的原因。对城区自动站与人工站气温观测记录差值进行统计学分析认为,该测温差值的形成与气象要素有一定关系,以此为据建立了统计学差值订正方程,经统计检验和2003年4～5月的实际检验均效果显著。自动站与常规站观测记录的差值分析表明,自动站虽有许多需要完善的地方,但现用仪器所测数据,其差值基本都在允许范围内或略超出允许范围,能满足日常业务使用。在观测时间的统一性上自动站优于人工站。

Abstract:Observation data of AWS-city from May 2001 to March 2002 and AWS-milos500 from January to may 2003 have been respectively contrasted with synchro conventional observation data. The cause analysis of the observation difference is made from their difference in sensor pieces and detecting principle, observation time, weather condition etc. Statistics analysis of the temperature error of AWS-city shows that the error is related with the weather factors. Based on that, the correction equations are given. Statistical test and actual verification proved that it had a better effect. The analysis shows that the observation differences of the AWS ere in or a little over the allowed scope, even thought they had many faults. AWS are superior to man-observed station at the aspect of the unifying of observation time.
