Paper Abstract

Satellite instruments detected two intense decreases of the ozone column values over Europe in November 1996 and November 1999. These low ozone events have been studied using atmospheric data and air parcel trajectory analyses. It was found that both ozone events were accompanied by rapid temperature decreases in the lower stratosphere. The anti-correlation found between total ozone and air parcel height along the air parcels trajectories suggested that the vertical displacement of air contributed significantly to the total ozone and temperature decreases observed. The Azores high-pressure cell over the mid Atlantic region, perturbed the flow in the lower stratosphere, forcing the vertical displacement of air parcels and causing the temperature and total ozone minima observed.
