宁河国家气象观测站迁站数据对比分析及评估

Analysis and evaluation on data comparison after relocating Ninghe national meteorological observatory station

通过对2017年1~12月宁河国家气象观测站迁站前后新旧站址气象观测资料进行对比分析,利用差值标准差、相对差值、显著性检验等计算方法,得出结论:新旧站址的气温、降水量、相对湿度及风向风速差异不大,新址气温偏低,降水量偏多,风速偏大,定时风向一致性较高。由于新址探测环境优越,无高层建筑等障碍物遮挡,相对旧址更具优势,新址观测资料完整,连续性、区域一致性及均一性较好,观测资料具有可用性。

Through the comparison and analysis of the meteorological observation data before and after the relocation of Ninghe national meteorological observation station from January to December in2017,by using the calculation methods of difference standard deviation,relative difference and significance test,the conclusion is drawn that there is little difference in temperature,precipitation,relative humidity,wind direction and wind speed between the old and new sites.The new site has low temperature,high precipitation,high wind speed and high consistency of timing wind direction.The new site has advantages over the old site due to its superior detection environment and the absence of obstacles such as high-rise buildings.The observational data of the new site are complete,with good continuity,regional consistency and homogeneity,and the observational data are available.
