Jet Formation and Evolution in Baroclinic Turbulence with Simple Topography
Publisher: American Meteorological Society
Abstract: Satellite altimetry and high-resolution ocean models indicate that the Southern Ocean comprises an intricate web of narrow, meandering jets that undergo spontaneous formation, merger, and splitting events, as well as rapid ...
Bottom Boundary Potential Vorticity Injection from an Oscillating Flow: A PV Pump
Publisher: American Meteorological Society
Abstract: ceanic boundary currents over the continental slope exhibit variability with a range of time scales. Numerical studies of steady, along-slope currents over a sloping bathymetry have shown that cross-slope Ekman transport ...
Configuration of a Southern Ocean Storm Track
Publisher: American Meteorological Society
Abstract: iagnostics of ocean variability that reflect and influence local transport properties of heat and chemical species vary by an order of magnitude along the Southern Ocean?s Antarctic Circumpolar Current (ACC). Topographic ...
Jets and Topography: Jet Transitions and the Impact on Transport in the Antarctic Circumpolar Current
Publisher: American Meteorological Society
Abstract: he Southern Ocean?s Antarctic Circumpolar Current (ACC) naturally lends itself to interpretations using a zonally averaged framework. Yet, navigation around steep and complicated bathymetric obstacles suggests that local ...
Connecting Antarctic Cross-Slope Exchange with Southern Ocean Overturning
Publisher: American Meteorological Society
Abstract: revious idealized investigations of Southern Ocean overturning have omitted its connection with the Antarctic continental shelves, leaving the influence of shelf processes on Antarctic Bottom Water (AABW) export unconsidered. ...
Two-Layer Baroclinic Eddy Heat Fluxes: Zonal Flows and Energy Balance
Publisher: American Meteorological Society
Abstract: The eddy heat flux generated by statistically equilibrated baroclinic turbulence supported on a uniform, horizontal temperature gradient is examined using a two-layer ?-plane quasigeostrophic model. The dependence of the ...
Equilibration 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 ...
Eddy Generation and Jet Formation via Dense Water Outflows across the Antarctic Continental Slope
Publisher: American Meteorological Society
Abstract: long various stretches of the Antarctic margins, dense Antarctic Bottom Water (AABW) escapes its formation sites and descends the continental slope. This export necessarily raises the isopycnals associated with lighter ...
Scaling Baroclinic Eddy Fluxes: Vortices and Energy Balance
Publisher: American Meteorological Society
Abstract: The eddy heat flux generated by the statistically equilibrated baroclinic instability of a uniform, horizontal temperature gradient is studied using a two-mode f-plane quasigeostrophic model. An overview of the dependence ...
Transient Overturning Compensation between Atlantic and Indo-Pacific Basins
Publisher: American Meteorological Society
Abstract: Climate models consistently project (i) a decline in the formation of North Atlantic Deep Water (NADW) and (ii) a strengthening of the Southern Hemisphere westerly winds in response to anthropogenic greenhouse gas forcing. ...
