| Zusammenfassung |
| In this study, low-frequency variations in temperature
anomaly are investigated by mapping temperature anomaly records onto random
walks. We show evidence that global overturns in trends of temperature
anomalies occur on decadal time-scales as part of the natural variability of
the climate system. Paleoclimatic summer records in Europe and New-Zealand
provide further support for these findings as they indicate that
anti-persistence of temperature anomalies on decadal time-scale have
occurred in the last 226 yrs. Atmospheric processes in the subtropics and
mid-latitudes of the SH and interactions with the Southern Oceans seem to
play an important role to moderate global variations of temperature on
decadal time-scales. |
