| 摘 要： | 针对气象台站气温观测资料序列存在站址迁移可能造成的资料非均一性影响,利用环县等6个站址迁移气象站的逐年平均气温、平均最高气温、平均最低气温序列,采用SNHT(标准正态检验)客观分析方法,结合6个气象站的元数据及历史沿革资料等信息进行主观分析,对因迁站造成的气温序列不均一性进行检验,表明站址迁移对气温资料影响较大,并且因地理地形环境而有所差异。结果表明:台站迁移后造成新旧站址的地理环境差异显著且海拔高度差异过大,是引起气温序列非均一性的主要原因。地理环境、气候条件相似的台站迁移对气温资料的均一性无明显影响。

| Abstract: | According to the observation data series, meteorological station temperature station migration may cause da- ta heterogeneity effect, with the data of address transfer 6 stations＇ as Huanxian etc., annual average temperature, average maximum temperature, average minimum temperature series, using the SNHT （standard normal test） objec- tive method, it has been carried out the subjective analysis metadata and history data and other information combined with the 6 meteorological stations to test the heterogeneity of the temperature sequence due to the temperature series moved stations. It shows that station migration has great influence on the temperature data for the geographical envi- ronment difference. The results also show that： the notable differences of geographical environment and the altitude values between the old and the new site are the chief reasons for the temperature sequence heterogeneity. The migra- tion stations with similar geographical environment and climatic conditions to the old ones are not affected in the uni- formity of temperature data. |
