Short summary
Stratospheric ozone is a crucial chemical substance that protects life on Earth from harmful ultraviolet radiation. This article demonstrates how a strong or a weak Arctic polar vortex has an impact on wintertime circulation activity and the concentration of ozone in the stratosphere. Our results suggest that changes in the strength of the polar vortex lead to not only significant and persistent ozone changes locally in the Arctic but also to evident ozone changes in the tropics.
