On the Strong Seasonal Currents in the Deep Ocean
Publisher: American Meteorological Society
Abstract: Using a set of models, including one with a resolution of ¼°, several aspects of the simulated seasonal currents in the deep ocean are considered. It is shown that over vast areas of the deep interior, particularly in the ...
On the Climatic Impact of Wind Stress
Publisher: American Meteorological Society
Abstract: A climate model is used to study the climatic impact of the stress exerted on the ocean by the atmosphere. When this stress is set to zero everywhere, the climate becomes much colder, with global-mean near-surface air ...
Influence of Global Warming on Baroclinic Rossby Radius in the Ocean: A Model Intercomparison
Publisher: American Meteorological Society
Abstract: Results from eight ocean?atmosphere general circulation models are used to evaluate the influence of the projected changes in the oceanic stratification on the first baroclinic Rossby radius of deformation in the ocean, ...
The Effect of Localized Mixing on the Ocean Circulation and Time-Dependent Climate Change
Publisher: American Meteorological Society
Abstract: Observations indicate that intense mixing in the ocean is localized above complex topography and near the boundaries. Model experiments presented here illustrate that accounting for this fact can be important. In particular, ...
Ocean Heat Transport and Its Projected Change in CanESM2
Publisher: American Meteorological Society
Abstract: he meridional ocean heat transport (MOHT), its seasonal variability, and projected changes simulated by the second generation Canadian Earth System Model (CanESM2) are presented. The global mean MOHT is within the uncertainty ...
Bottom-Enhanced Diapycnal Mixing Driven by Mesoscale Eddies: Sensitivity to Wind Energy Supply
Publisher: American Meteorological Society
Abstract: t has been estimated that much of the wind energy input to the ocean general circulation is removed by mesoscale eddies via baroclinic instability. While the fate of this energy remains a subject of research, arguments ...
Human-Induced Change in the Antarctic Circumpolar Current
Publisher: American Meteorological Society
Abstract: Global climate models indicate that the poleward shift of the Antarctic Circumpolar Current observed over recent decades may have been significantly human induced. The poleward shift, along with a significant increase in ...
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. ...
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 ...
