PO51A:
Atlantic Meridional Overturning Circulation: Past, Present, and Future IV


Session ID#: 11463

Session Description:
The Atlantic Meridional Overturning Circulation (AMOC) comprises warm upper waters flowing northward, becoming colder and denser until they form deep water in the Nordic and Labrador Seas that then returns southward through the North and South Atlantic. The AMOC transports a substantial amount of heat from the tropics and Southern Hemisphere toward the North Atlantic, where the heat is then transferred to the atmosphere. Consequently, changes in the AMOC could have a profound impact on many aspects of the global climate system. Climate models in unforced control integrations, simulate a rich spectrum of internal AMOC variability on seasonal, through decadal and multidecadal, to multicentennial timescales. The AMOC is also thought to be externally driven, e.g. by solar variability and changing volcanic activity. Anthropogenic climate change may also impact the AMOC, and most climate models project a significant slowing by the end of the century.

We invite contributions on the AMOC of the past millennium, studies that describe the present state of the AMOC including its dynamics, mechanisms of property transport, short-term temporal and spatial variability, and work addressing the future evolution of the AMOC. Observational (proxy and instrumental) as well as modelling studies are welcome.
