RISRadiation and Dissipation of Internal Waves Generated by Geostrophic Motions Impinging on Small-Scale Topography: Theory
Publisher: American Meteorological Society
Abstract: Observations and inverse models suggest that small-scale turbulent mixing is enhanced in the Southern Ocean in regions above rough topography. The enhancement extends O(1) km above the topography, suggesting that mixing ...
A Theory of the Interhemispheric Meridional Overturning Circulation and Associated Stratification
Publisher: American Meteorological Society
Abstract: quantitative theoretical model of the meridional overturning circulation and associated deep stratification in an interhemispheric, single-basin ocean with a circumpolar channel is presented. The theory includes the effects ...
Downstream Propagation and Remote Dissipation of Internal Waves in the Southern Ocean
Publisher: American Meteorological Society
Abstract: AbstractRecent microstructure observations in the Southern Ocean report enhanced internal gravity waves and turbulence in the frontal regions of the Antarctic Circumpolar Current extending a kilometer above rough bottom ...
Suppression of Eddy Diffusivity across Jets in the Southern Ocean
Publisher: American Meteorological Society
Abstract: Geostrophic eddies control the meridional mixing of heat, carbon, and other climatically important tracers in the Southern Ocean. The rate of eddy mixing is typically quantified through an eddy diffusivity. There is an ...
Radiation and Dissipation of Internal Waves Generated by Geostrophic Motions Impinging on Small-Scale Topography: Application to the Southern Ocean
Publisher: American Meteorological Society
Abstract: Recent estimates from observations and inverse models indicate that turbulent mixing associated with internal wave breaking is enhanced above rough topography in the Southern Ocean. In most regions of the ocean, abyssal ...
A Mechanism for Local Dissipation of Internal Tides Generated at Rough Topography
Publisher: American Meteorological Society
Abstract: Fine- and micro-structure observations indicate that turbulent mixing is enhanced within O(1) km above rough topography. Enhanced mixing is associated with internal wave breaking and, in many regions of the ocean, has been ...
A Theory of Deep Stratification and Overturning Circulation in the Ocean
Publisher: American Meteorological Society
Abstract: A simple theoretical model of the deep stratification and meridional overturning circulation in an idealized single-basin ocean with a circumpolar channel is presented. The theory includes the effects of wind, eddies, and ...
Maintenance of the Zonal Momentum Balance of the Antarctic Circumpolar Current by Barotropic Dynamics
Publisher: American Meteorological Society
The Impact of Finite-Amplitude Bottom Topography on Internal Wave Generation in the Southern Ocean
Publisher: American Meteorological Society
Abstract: irect observations in the Southern Ocean report enhanced internal wave activity and turbulence in a kilometer-thick layer above rough bottom topography collocated with the deep-reaching fronts of the Antarctic Circumpolar ...
Sensitivity of the Ocean State to Lee Wave–Driven Mixing
Publisher: American Meteorological Society
Abstract: iapycnal mixing plays a key role in maintaining the ocean stratification and the meridional overturning circulation (MOC). In the ocean interior, it is mainly sustained by breaking internal waves. Two important classes of ...
