On the Variability of the Stratosphere in the Arctic Regions in Winter
Abstract The arctic stratosphere is much more variable in winter, and from one winter to another, than is the antarctic stratosphere. The latter stays cold and intense through the winter, whereas the former is subject to minor and major midwinter warmings. During the major midwinter warmings the arc...

| Summary: | Abstract The arctic stratosphere is much more variable in winter, and from one winter to another, than is the antarctic stratosphere. The latter stays cold and intense through the winter, whereas the former is subject to minor and major midwinter warmings. During the major midwinter warmings the arctic warms up and the cyclonic vortex — normally centered near the North Pole — divides into two centers which move south while an anticyclone becomes established near the pole. — Because the antarctic polar cyclonic vortex remains cold and centered near the pole till the end of winter, conditions favorable for the development of an ozone hole exist when the sun returns in spring. This is in contrast to the disturbed conditions in the arctic which usually keep the temperature at a level that is not conducive to large‐scale destruction of ozone. |
