摘　　要：通过山西北部四个站（Ａ、Ｂ、Ｃ、Ｄ）１９９３年春、秋代表月份测试探空剖面的统计分析，得到了该地区大气结构水平不均匀特性的有关结果，证明了该地区的大气结构存在着水平不均匀性，尤其是低层大气的水平不均匀性较大。这种水平不均匀性是随时空变化的，其中早、晚最大，下午较小。同时也讨论了用＂五九＂型探空仪探测大气折射率Ｎ剖面的测量误差。The result of horizontal inhomogeneity of atmospheric structure is obtained by analyzing tile observational using radio-sonde at four stations (A, B. C, D) in the North of Shanxi during tile month of spring and autumn 1993. It is proved that there is the horizontal horizontal of atmospheric structure in the area. Especially the horizontal inhomogeneity of the atmospheric structure is large in lower layer. This inhomogeneity varies with time and space. The variation is larger in the morning and evening than in the afternoon. Tile measuring error of atmospheric refractivity N profile with model-59 radio-sonde is also discussed.
