| Zusammenfassung |
| We show that in order to have a scaling description of the climate system that is not
inherently non-stationary, the rapid shifts between stadial and interstadial conditions
during the last glaciation cannot be included in the scaling law. The same is true
for the shifts between the glacial and interglacial states in the quaternary climate.
When these events are omitted from a scaling analysis we find that the climate
noise is consistent with a 1∕f law on time scales from months to 105 years. Using
wavelet-based structure-function analysis we find no evidence of multifractal intermittency. |
