南极臭氧洞的发现、研究和启示

The Antarctic Ozone Hole and its Discovery,Research and Inspiration

回顾了南极臭氧洞的发现过程,评述了南极臭氧洞形成和发展的机制、以及南北极臭氧变化的差异,讨论了南极臭氧洞的发现和研究带来的启示。研究指出,目前只是在南极春季出现了臭氧洞,北极并没有出现过臭氧洞。在当前大气环境被污染的情况下,极地大气臭氧亏损的程度将更多地随大气环流,特别是极地涡旋中的低温状况而发生变化。

This study reviews the detection and the variety of the Antarctic ozone hole;the reason why the ozone hole is formed over the Antarctic is discussed,while the different patterns of the ozone variation over the Arctic and the Antarctic are outlined.It is also discussed the inspiration obtained throughout the detection and research of Antarctic ozone hole.It is pointed out that,currently,the ozone hole appears only in spring over the Antarctic and not appeared yet over the Arctic.Under the current atmospheric environment with the added pollution,the change of atmospheric ozone depletion over the Polar Regions will be more dependent on the atmospheric circulation,especially the low temperature in the polar vortex.
