南极平流层的臭氧空洞有两个基本参数：深度和大小。本文利用1982-2003年9月、10月和11月的月平均资料，分析了臭氧空洞大小的演变。在对数据序列子集分析的基础上，我们发现1995-2003年10月和11月期间OHS趋势出现逆转的信号。另一方面，9月份OHS亚集的变化趋势与地磁Ap指数和10.7 cm太阳通量指数的变化趋势基本一致。检测到的恢复过程的开始是一个很好的模型测试，以匹配观测值。
[1] The Antarctic ozone hole in the stratospheric layer has two basic parameters: depth and size. In this work the evolution of the ozone hole size (OHS) is analyzed using the monthly mean data for September, October, and November during 1982–2003. On the basis of the analysis of subsets of the data series we found signals of a reversal in the OHS trend during the period 1995–2003 for the months of October and November. On the other hand, the trends of the OHS subsets for the month of September show cyclical changes that approximately follow the variations of the geomagnetic Ap index and the 10.7-cm solar flux index. The detected beginning of the recovery process is a good test for models in order to match observations.
