Introduction: The ocean's meridional overturning circulation [chapter]

Andreas Schmittner, John C.H. Chiang, Sidney R. Hemming
2007 Ocean Circulation: Mechanisms and Impacts—Past and Future Changes of Meridional Overturning  
The meridional overturning circulation is a system of surface and deep currents encompassing all ocean basins.  ...  It transports large amounts of water, heat, salt, carbon, nutrients and other substances around the globe, and connects the surface ocean and atmosphere with the huge reservoir of the deep sea.  ...  Schmittner, Brook, and Ahn use a coupled climate carbon cycle model to suggest that changes in Southern Ocean stratification caused by a reduction of North Atlantic Deep Water formation are important in  ...

Physical controls of Southern Ocean deep-convection variability in CMIP5 models and the Kiel Climate Model

A. Reintges, T. Martin, M. Latif, W. Park
2017 Geophysical Research Letters  
We investigate the physical controls of this variability in the Atlantic sector of the Southern Ocean, where most of the models simulate recurring deep-convection events.  ...  Key Points:  Variability of open-ocean deep-convection varies widely among climate models with implications reaching beyond the Southern Ocean  Stratification influences the timescale of deep-convection  ...  Acknowledgments We acknowledge the World Climate Research Programme's Working Group on Coupled Modelling, which is responsible for CMIP, and we thank the climate modeling groups for producing and making  ...

PMIP contributions to understanding the deep ocean circulation of the Last Glacial Maximum

2021 Past Global Change Magazine  
In the modern climate, North Atlantic Deep Water (NADW), which forms in the Nordic and Labrador Seas, fills the deep North Atlantic basin.  ...  The global climate was much colder than the modern climate, and the state of the Atlantic Meridional Overturning Circulation (AMOC) was very different as a consequence of the glacial climate forcings.  ...  Large SST biases are evident over the Southern Ocean and northern North Atlantic, where AAbW and NADW are formed, respectively.  ...
