摘　　要：采用季节划分和季节突变的概念、理论及方法，对44a（1958～2001年）的大气臭氧资料及对流层顶气压场资料进行了计算，并分析了对流层顶大气臭氧的季节变化．结果发现对流层顶大气臭氧的季节变化在全球大部分区域中的突变性都比较明显，表明对流层顶大气臭氧的季节变化受到上对流层和下平流层中多种因素的影响．通过分析还发现，利用曾庆存所定义的参数Rw（t）及有关的一些概念和方法确能很好地反映对流层顶大气臭氧的季节变化．Using general concepts, theories and methods which about the season division and the abruptness,44 years （1958--2001） atmospheric ozone and data sets of pressure at tropopause were calculated, and the seasonal variation of the tropopause atmospheric ozone were analyzed. It was found that the seasonal variation of the tropopause atmospheric ozone in most regions were abrupt, it meant that the situation of the seasonal variation in many regions were equivalent to many factors in the upper troposphere and the lower stratosphere. According to the analytics it was also found that ：using the parameter of Rw（t） and some concerned concepts and methods, the seasonal variation of the tropopause atmospheric ozone are firmly reflected.
