Abrupt climate change due to mode switches
circulation modes of the glacial Atlantic
Schematic representation of three
modes of operation of the climate system during the Last Ice
The large Earth in the centre shows the stable
"stadial") climate state prevailing during most of the Ice Age.
Below it is the situation during a warm
(D/O) event, in which the Atlantic conveyor belt temporarily advances
the Nordic Seas and a strong warm anomaly develops there
The upper globe shows climate during a Heinrich
with collapsed conveyor belt and a cold anomaly over the mid-latitude
The continental ice cover shown is the
of Peltier, prescribed as a boundary condition in the model simulations.
