RISSouthern Ocean Response to Strengthening Winds in an Eddy-Permitting Global Climate Model
Publisher: American Meteorological Society
Abstract: A global climate model with horizontal resolutions in the ocean ranging from relatively coarse to eddy permitting is used to investigate the resolution dependence of the Southern Ocean response to poleward intensifying ...
The Southern Ocean Overturning: Parameterized versus Permitted Eddies
Publisher: American Meteorological Society
Abstract: Four versions of the same global climate model, with horizontal resolution ranging from 1.8° ? 3.6° to 0.2° ? 0.4°, are employed to evaluate the resolution dependence of the Southern Ocean meridional overturning circulation. ...
The Key Role of the Western Boundary in Linking the AMOC Strength to the North–South Pressure Gradient
Publisher: American Meteorological Society
Abstract: key idea in the study of the Atlantic meridional overturning circulation (AMOC) is that its strength is proportional to the meridional density gradient or, more precisely, to the strength of the meridional pressure gradient. ...
On Challenges in Predicting Bottom Water Transport in the Southern Ocean
Publisher: American Meteorological Society
Abstract: hanges in the Southern Ocean lower-limb overturning circulation are analyzed using a set of climate models. In agreement with some recently developed theoretical models, it is found that the overturning can be strongly ...
North Atlantic Climate Response to Lake Agassiz Drainage at Coarse and Ocean Eddy-Permitting Resolutions
Publisher: American Meteorological Society
Abstract: he North Atlantic climate response to the catastrophic drainage of proglacial Lake Agassiz into the Labrador Sea is analyzed with coarse and ocean eddy-permitting versions of a global coupled climate model. The North ...
The Role of Bottom Pressure Torques on the Interior Pathways of North Atlantic Deep Water
Publisher: American Meteorological Society
Abstract: our versions of the same global climate model, one with horizontal resolution of 1.8° ? 3.6° and three with 0.2° ? 0.4°, are employed to evaluate the role of ocean bottom topography and viscosity on the spatial structure ...

Mechanisms Maintaining Southern Ocean Meridional Heat Transport under Projected Wind Forcing
Publisher: American Meteorological Society
Abstract: eridional heat transport (MHT) in the Southern Ocean (SO) and its components are analyzed with two eddy-permitting climate models. The two models present a consistent picture of the MHT response to projected twenty-first-century ...
Using Eulerian and Lagrangian Approaches to Investigate Wind-Driven Changes in the Southern Ocean Abyssal Circulation
Publisher: American Meteorological Society
Abstract: his study uses a global ocean eddy-permitting climate model to explore the export of abyssal water from the Southern Ocean and its sensitivity to projected twenty-first-century poleward-intensifying Southern Ocean wind ...
The Energetics of Southern Ocean Upwelling
Publisher: American Meteorological Society
Abstract: he ocean?s meridional overturning circulation is closed by the upwelling of dense, carbon-rich waters to the surface of the Southern Ocean. It has been proposed that upwelling in this region is driven by strong westerly ...
