| 摘 要： | 采用回归检验法对山东省120个台站1961~2005年的年平均气温序列进行了显著非均一性检验。通过与台站历史沿革信息的比较分析,表明在显著性水平α=0.01时回归检验法能有效地检验出年平均气温序列的非均一性。分析结果显示,气象台站的位置、环境、观测方法和时制、仪器类型和高度等变动,对年平均气温序列的非均一性均有不同程度的影响,其中台站迁移对温度序列的均一性影响最大。

| Abstract: | The homogeneity test of annual mean temperature series is carried out using annual mean temperature over Shandong Province from 1961 to 2005 by means of the regressive method.Through the contrastive analysis of the historical information about meteorological station,it is found that the regressive method can be applied to the homogeneity test on the annual mean temperature series with the significance level being 0.01.The results show that the relocation,environment,observational instrument type or observation time of stations have direct effects on the continuity of observational records and the homogeneity of climatological data.Especially,the change of observation station location is the most important factor. |
