摘要

[Objective]The research aimed to contrast parallel observation data of pressure and temperature in Qingxian station.[Method]By using pressure and temperature observed by automatic station and artificial station in Qingxian from January of 2009 to December of 2010,comparative analysis of observation data was conducted,and formation reason of difference value was discussed.[Result]Monthly average pressure difference between automatic station and artificial observation value was from-0.7 to 0.1 hPa.Difference value of monthly average maximum pressure was from-0.5 to 0.4 hPa,while difference value of monthly average minimum pressure was from-0.7 to 0.2 hPa.Difference value of monthly extremely maximum pressure was from-0.3 to 0.6 hPa,while difference value of monthly extremely minimum pressure was from-1.1 to 0.1 hPa.Monthly average temperature difference value was from-2.0 to 0℃.Difference value of monthly average maximum temperature was from-0.4to 0℃,while difference value of monthly average minimum temperature was from-0.1 to 0.2℃.Difference value of monthly extremely maximum temperature was from-0.3 to 0.3℃,while difference value of monthly extremely minimum temperature was from-0.3 to 0.3℃.[Conclusion]Generation reason of observation difference mainly included differences of observation instrument and principle,differences of data collection time and method,different sensor installation positions and environments,manual intervention and observation error.
