| Zusammenfassung |
| Long-term measurements of polar ozone show an unexpectedly large decadal scale
variability in the mid-stratosphere during winter. Negative ozone anomalies are
strongly correlated with the flux of energetic electrons in the radiation belt,
which is modulated by the 11-year solar cycle. The magnitude of the observed
decadal ozone changes (≈20%) is much larger than any previously
reported solar cycle effect in the atmosphere up to this altitude. The
early-winter ozone anomalies subsequently propagate downward into the lower
stratosphere and may even influence total ozone and meteorological conditions
during spring. These findings suggest a previously unrecognized mechanism by
which solar variability impacts on climate through changes in polar ozone. |
