摘要
通过构建参考序列、找出间断点、结果集成等步骤对内蒙古地区119个地面气象站逐日平均气温、逐日最高气温、逐日最低气温进行均一性检验。结果表明:内蒙古地区大部分地面气象站气温资料均一性状况良好;部分台站气温资料不均一的原因主要是受迁站影响,其次是观测站周围环境变化、观测仪器的更换以及观测标准的变更。不均一现象对最低气温影响较大,其次是平均气温,最高气温受影响相对最小。
By the steps of constructing the reference series, finding breakpoint, result integration and so on, the uniformity of daily average air temperature, daily maximum temperature and daily minimum temperature of 119 weather stations in Inner Mongolia was tested. The results showed that： the uniformity condition of air temperature data of the most weather stations in Inner Mongolia Inner was well. The main causes of the air temperature data inhomogeneity were meteorological observation station moved, followed by changes of surrounding environment observatory, observation equipment replacement and the observation standard changes, inhomogeneity phenomenon greater impact on the minimum temperature data, followed by the average temperature data, maximum temperature was affected relatively minimal.
