Abstract
This paper reviews results related to the influence of long‐term changes of the atmospheric wave activity and circulation on the ozone layer, in particular on the Antarctic ozone hole in 2002. These results provide evidence that an important role is played by natural factors in the ozone layer changes, together with the known anthropogenic impacts. Specifically, these factors are connected with the interannual and decadal variations in the coupled ocean–atmosphere system of the Northern and Southern Hemispheres. Possible mechanisms of long‐term changes of the ozone layer and climate are discussed.
