| Zusammenfassung |
| The response of atmospheric energy transport during Northern Hemisphere
cooling and warming from present day (PD) and Last Glacial Maximum (LGM)
conditions is investigated using sea surface temperature anomalies derived
from a freshwater hosing experiment. The present day climate shows enhanced
sensitivity of the atmospheric mid-latitude energy transport compared to
that of the LGM, suggesting its ability to reorganize more easily and thereby
dampen high latitude temperature anomalies that may arise from changes in
the oceanic transport. This effect is found to be a result of both the
atmospheric and surface flux response. The increased PD transport
sensitivity relative to that of the LGM is linked to a stronger dry static
energy transport response which, in turn, is mainly driven by larger changes
in the transient eddy heat flux. In comparison, changes in mid-latitude
latent heat transport play a minor role in the overall transport
sensitivity. |
