中文摘要：

通过分析1992-2001年的HALOE卫星资料，给出了各纬度带平流层的臭氧混合比的纬向分布结构，并分析了其季节变化的特征，同时，利用NCEP／NCAR再分析资料，分析了平流层行星波的结构及其与臭氧纬向分布的关系。结果表明：平流层臭氧混合比的纬向分布季节差异较大，在两半球的夏季平流层臭氧混合比的纬向分布较均匀，其它季节在中高纬的臭氧混合比高值区有一些扰动，并且随着纬度的增大其扰动加强，其中冬季它的扰动最强，这些都与平流层的行星波有相同的特点。对这两种资料进行波谱分析发现，在冬半球臭氧混合比在中高纬的纬向扰动有明显的1波信号，并且与位势高度的1波扰动有相同的位相，因此认为臭氧纬向扰动主要是由行星波引起的，并且在中高纬主要是1波的影响；而低纬地区由于不满足行星波上传的条件，所以臭氧纬向分布不受行星波的影响。分析行星波扰动对臭氧的输送作用也表明，行星波的扰动确实引起臭氧在经向上的输送，从而造成臭氧纬向分布的不对称，并且由于基本气流的输送作用，使得臭氧纬向扰动与行星波造成的原始扰动有一个位相差。

英文摘要：

The HALOE data from 1992 to 2001 are used to analyze the zonal distributions and the seasonal variations of O3 mixing ratio in the stratosphere at different latitudes, the results indicate that there are obvious differences of zonal distributions of O3 mixing ratio in the stratosphere between different seasons. In summer of either NH or SH, the zonal distributions of O3 mixing ratio are rather small in the stratosphere, and there are disturbances at the middle-high latitudes in other seasons, which strengthen a- long with the latitude increase and are the strongest in winter. The seasonal variations of O3 zonal disturbance are similar to the strength of planetary wave in the stratosphere. Together with the NCEP/ NCAR reanalysis data, it is shown that the clear signals of wave 1 obtained from the O3 zonal disturbance and the geopotential height disturbance, which are nearly in phase in DJF at the middle-high latitudes. So the O3 zonal disturbances are resulted from the planetary wave in the stratosphere. At the middle-high latitudes, wave 1 play the most important role in the O3 zonal disturbances, while at 30°, the relationship between O3 zonal disturbances and planetary wave is not very close. At low latitude, planetary wave cannot propagate upward to the stratosphere to affect O3 zonal distributions. The results are due to meridional O3 transportation by disturbance flows and influence of basic flow makes observed O3 disturbance having different phases with the origin disturbance.
