Abstract

Satellite measurements indicate that mid-latitude ozone depletion in the Northern Hemisphere spring during 1979-97 was worst over Europe and Russia. Here we show that these longitudinal differences in ozone trends are due to a combination of decadal variations in the circulation and transport of ozone-depleted air from the polar vortex. Any increase in ozone depletion in the polar vortex as a result of future cooling of the stratosphere would therefore be particularly bad over Europe and Russia.
