PL34A:
Atlantic Meridional Overturning Circulation: Modeling and Observations V Posters


Session ID#: 38013

Session Description:
Through its associated heat, salt, and carbon transports, the Atlantic Meridional Overturning Circulation (AMOC) significantly influences the climate of the North Atlantic and surrounding areas and can even impact global climate through interactions with atmosphere on seasonal to multi-decadal timescales. Because the memory of the ocean vastly exceeds that of the atmosphere, AMOC is thought to represent the dynamical memory of the climate system, playing a major role in climate variations, hence in climate predictions, on these and even longer, i.e., centennial to millennial, timescales. Support for such a prominent role for AMOC on long time scales comes from coupled general circulation model simulations and proxy records. On shorter, i.e., intra-seasonal to decadal, timescales, measurements of transports, heat content, and other variables throughout the Atlantic Ocean have been instrumental in investigating the spatial structure, mechanisms, and impacts of AMOC variability, showing the importance of processes from the mesoscale to the basin scale. A synergy of knowledge gained from all these efforts will lead to a better understanding of AMOC.

We invite contributions from modeling and observational (both instrumental and proxy) studies, investigating AMOC variability and mechanisms as well as its role in climate predictions on various, e.g., decadal, timescales.
