摘　　要：Both the Antarctic and Arctic polar stratospheres are occupied with giant cyclonic vortices in their winter seasons [1].These vortices are bounded by strong westerly winds,i.e.,the polar night jets.Air within the stratospheric polar vortices is thus relatively isolated from the extratropical stratosphere.Because of the isolation and the lack of solar radiation during the polar night season.Both the Antarctic and Arctic polar stratospheres are occupied with giant cyclonic vortices in their winter seasons [1].These vortices are bounded by strong westerly winds,i.e.,the polar night jets.Air within the stratospheric polar vortices is thus relatively isolated from the extratropical stratosphere.Because of the isolation and the lack of solar radiation during the polar night season.
