Structure and variability of stratospheric planetary waves were analyzed by use of satellite data. It was found that in the southern hemisphere stratosphere wavenumber 2 component moves eastward unlike its northern hemispehre conuterpart. The component played an essential role in producing the strong sudden warming observed 1988 southern spring. A 2-dimensional photochemical/dynamical model of the atmospheric ozone was developed. Computed ozone distributions on the meridional plane are in good agreement with the observations.

利用卫星资料分析了平流层行星波的结构和变率。结果表明，在南半球平流层中，波数2分量向东移动，而在北方半球则相反。该成分在1988年南方春季观测到的强烈突然变暖中起了重要作用。建立了一个二维大气臭氧的光化学/动力学模式。计算得到的臭氧在纬向面上的分布与观测值符合得很好。
