RISEquilibration of the Antarctic Circumpolar Current by Standing Meanders
Publisher: American Meteorological Society
Abstract: he insensitivity of the Antarctic Circumpolar Current (ACC)?s prominent isopycnal slope to changes in wind stress is thought to stem from the action of mesoscale eddies that counterbalance the wind-driven Ekman overturning?a ...
A Conjecture on the Role of Bottom-Enhanced Diapycnal Mixing in the Parameterization of Geostrophic Eddies
Publisher: American Meteorological Society
Abstract: The parameterization of geostrophic eddies represents a large sink of energy in most ocean models, yet the ultimate fate of this eddy energy in the ocean remains unclear. The authors conjecture that a significant fraction ...
Internal Waves and Turbulence in the Antarctic Circumpolar Current
Publisher: American Meteorological Society
Abstract: his study reports on observations of turbulent dissipation and internal wave-scale flow properties in a standing meander of the Antarctic Circumpolar Current (ACC) north of the Kerguelen Plateau. The authors characterize ...
Water Mass Conversion, Fluxes, and Mixing in the Scotia Sea Diagnosed by an Inverse Model
Publisher: American Meteorological Society
Abstract: An inverse box model of the Scotia Sea is constructed using hydrographic, tracer, and velocity data collected along the rim of the basin during the Antarctic Large-Scale Box Analysis and the Role of the Scotia Sea (ALBATROSS) ...
Influence of the Distortion of Vertical Wavenumber Spectra on Estimates of Turbulent Dissipation Using the Finescale Parameterization: Eikonal Calculations
Publisher: American Meteorological Society
Variability of Subantarctic Mode Water and Antarctic Intermediate Water in the Drake Passage during the Late-Twentieth and Early-Twenty-First Centuries
Publisher: American Meteorological Society
Abstract: A time series of the physical and biogeochemical properties of Subantarctic Mode Water (SAMW) and Antarctic Intermediate Water (AAIW) in the Drake Passage between 1969 and 2005 is constructed using 24 transects of measurements ...
Eddy-Induced Modulation of Turbulent Dissipation over Rough Topography in the Southern Ocean
Publisher: American Meteorological Society
Abstract: esoscale eddies are universal features of the ocean circulation, yet the processes by which their energy is dissipated remain poorly understood. One hypothesis argues that the interaction of strong geostrophic flows with ...
Suppression of Internal Wave Breaking in the Antarctic Circumpolar Current near Topography
Publisher: American Meteorological Society
Abstract: imultaneous full-depth microstructure measurements of turbulence and finestructure measurements of velocity and density are analyzed to investigate the relationship between turbulence and the internal wave field in the ...
The Impact of Small-Scale Topography on the Dynamical Balance of the Ocean
Publisher: American Meteorological Society
Abstract: he impact of small-scale topography on the ocean?s dynamical balance is investigated by quantifying the rates at which internal wave drag extracts (angular) momentum and vorticity from the general circulation. The calculation ...
Sensitivity of the Overturning Circulation in the Southern Ocean to Decadal Changes in Wind Forcing
Publisher: American Meteorological Society
Abstract: he sensitivity of the overturning circulation in the Southern Ocean to the recent decadal strengthening of the overlying winds is being discussed intensely, with some works attributing an inferred saturation of the Southern ...
