Possible impact of polar stratospheric processes on mid-latitude vertical ozone distributions

Abstract

Balloon-borne ozone soundings have also been performed as part of European Arctic Stratospheric Ozone Experiment (EASOE) at Lindenberg, Hohenpeissenberg and Athens. Differences between these stations will be discussed with regard to the vertical ozone distributions and the features of stratospheric circulation during winter. The results give some evidence on the impact of chemically-disturbed air from the Arctic stratosphere to mid-latitudes from January until the middle of February during EASOE-winter in 1992. Ozone depletion is significantly pronounced at greater altitudes in mid-latitudes as it develops in polar latitudes.
