| Zusammenfassung |
The total ozone distribution in March 1997
showed very low values in the North Atlantic-European region, even lower than in
the years before. A spatial pattern correlation between the zonally asymmetric
part of total ozone and that of the 300 hPa surface geopotential of the Northern
Hemisphere was applied to examine the spatial structure of the low ozone values
and its dynamic dependence. A trend analysis in the North Atlantic-European
region was carried out to determine to what extent the low March 1997 ozone
values are related to the decadal change of meteorological parameters in the
lower stratosphere, observed since the 1980s, in comparison to the interannual
variability. The conclusion is that the very low ozone values above the North
Atlantic-European region in March 1997 were mainly induced by dynamic processes,
namely their decadal change as well as their interannual variability.
