Ozone during stratospheric warmings at Uccle

Abstract

The day-to-day variations in ozone content at Uccle (51°N) during some stratospheric warming events are examined. In particular, the attention is focused on the timing of commencement of ozone enhancement prior to peak day of warming and on the relationship in the ozone content between the upper and lower stratosphere. These two features are compared with the predictions of ozone transport models. There seems to be an agreement between model predictions and observed features in some cases.
