利用Nimbus-7卫星1979-82年4年的臭氧总量资料和NMC全球对流层顶分析资料，在5° × 5°网格上分析了对流层顶臭氧总量与对流层顶气压的关系。通过球谐展开的领域被分成中（天气）和大的空间尺度。给出了各季节的变率和相关性的全球分布。大规模的分析主要是基于从1979年的数据，由于热带对流层顶数据的时间不均匀性明显。天气尺度在两个半球的中纬度地区显示出较强的相关性（>0.6），向赤道迅速下降，向极地逐渐下降：使用直接从台站数据中得出的对流层顶值发现了对纬度的类似依赖性。在一个季节内，相关性最高的区域往往与风暴轴区域的最大方差区域有关。与此相反，季节的依赖性是这样的，夏季半球往往有更多的…
Abstract The relationship between total ozone and tropopause pressure is analyzed using 4 years (1979–82) of Nimbus-7 total ozone data and NMC global analyses of tropopause on a 5° by 5° grid. The fields are separated into medium (synoptic) and large spatial scales via a spherical harmonic expansion. The global distribution of variability and correlation are presented for each season. The large-scale analysis is based primarily on data from 1979 due to pronounced temporal inhomogeneities in the tropical tropopause data. The synoptic scales show strong correlations (>0.6) in the middle latitudes of both hemispheres with a rapid equatorward drop and a more gradual poleward decline: a similar dependence on latitude is found using tropopause values derived directly from station data. Within a season, the areas of highest correlation tend to be associated with the regions of maximum variance of the storm track regions. In contrast, the seasonal dependence is such that the summer hemispheres tend to have the mo...
