Spontaneous Surface Generation and Interior Amplification of Internal Waves in a Regional-Scale Ocean Model
Publisher: American Meteorological Society
Abstract: ecent theories, models, and observations have suggested the presence of significant spontaneous internal wave generation at density fronts near the ocean surface. Spontaneous generation is the emission of waves by unbalanced, ...
Reshaping the Antarctic Circumpolar Current via Antarctic Bottom Water Export
Publisher: American Meteorological Society
Abstract: AbstractZonal momentum input into the Antarctic Circumpolar Current (ACC) by westerly winds is ultimately removed via topographic form stress induced by large bathymetric features that obstruct the path of the current. ...
Southern Ocean Circulation and Eddy Compensation in CMIP5 Models
Publisher: American Meteorological Society
Abstract: hirteen state-of-the-art climate models from phase 5 of the Coupled Model Intercomparison Project (CMIP5) are used to evaluate the response of the Antarctic Circumpolar Current (ACC) transport and Southern Ocean meridional ...
Interdecadal Variability of the Southern Ocean
Publisher: American Meteorological Society
Abstract: The intrinsic variability of the Antarctic Circumpolar Current is investigated using an idealized wind-driven model. The model uses three quasigeostrophic layers, with steady wind stress forcing, and no diabatic effects. ...
Intrinsic Oceanic Decadal Variability of Upper-Ocean Heat Content
Publisher: American Meteorological Society
Available Potential Energy and Irreversible Mixing in the Meridional Overturning Circulation
Publisher: American Meteorological Society
Abstract: The overturning circulation of the global oceans is examined from an energetics viewpoint. A general framework for stratified turbulence is used for this purpose; first, it highlights the importance of available potential ...
Southern Ocean Response to Relative Velocity Wind Stress Forcing
Publisher: American Meteorological Society
Abstract: An eddy-resolving quasigeostrophic model of the Southern Ocean coupled to a dynamic atmospheric mixed layer is used to compare the performance of two different wind stress parameterization schemes. The first is the standard ...
The Energetics of a Collapsing Meridional Overturning Circulation
Publisher: American Meteorological Society
Abstract: well-studied example of natural climate variability is the impact of large freshwater input to the polar oceans, simulating glacial melt release or an amplification of the hydrological cycle. Such forcing can reduce, or ...
Eddy Cancellation of the Ekman Cell in Subtropical Gyres
Publisher: American Meteorological Society
Abstract: he presence of large-scale Ekman pumping associated with the climatological wind stress curl is the textbook explanation for low biological activity in the subtropical gyres. Using an idealized, eddy-resolving model, it ...
Response of Southern Ocean Convection and Abyssal Overturning to Surface Buoyancy Perturbations
Publisher: American Meteorological Society
Abstract: his study explores how buoyancy-driven modulations in the abyssal overturning circulation affect Southern Ocean temperature and salinity in an eddy-permitting ocean model. Consistent with previous studies, the modeled ...
