| Zusammenfassung |
| In a transient simulation of the last deglaciation with a fully coupled
model (TraCE-21000), an overshoot of the Atlantic Meridional Overturning
Circulation (AMOC) is simulated and proposed as a key factor for the onset
of the Bølling-Allerød (BA) warming event. There is collaborating
evidence for an AMOC overshoot at the BA in various proxy reconstructions
although the mechanism governing its behavior is not well understood. Here,
we present two new sensitivity experiments to explicitly illustrate the
impact of North Atlantic – GIN Sea exchange on the AMOC's deglacial
evolution. Results show that this oceanic exchange dominates the convection
restarting in the GIN Sea, the occurrence of the AMOC overshoot, and the
full BA warming. |
