Mesoscale Eddy–Internal Wave Coupling. Part II: Energetics and Results from PolyMode
Publisher: American Meteorological Society
Abstract: The issue of internal wave?mesoscale eddy interactions is revisited. Previous observational work identified the mesoscale eddy field as a possible source of internal wave energy. Characterization of the coupling as a viscous ...
Mesoscale Eddy–Internal Wave Coupling. Part I: Symmetry, Wave Capture, and Results from the Mid-Ocean Dynamics Experiment
Publisher: American Meteorological Society
Abstract: Vertical profiles of horizontal velocity obtained during the Mid-Ocean Dynamics Experiment (MODE) provided the first published estimates of the high vertical wavenumber structure of horizontal velocity. The data were ...
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 ...
Finescale Parameterizations of Turbulent Dissipation
Publisher: American Meteorological Society
Abstract: Fine- and microstructure data from a free fall profiler are analysed to test models that relate the turbulent dissipation rate (?) to characteristics of the internal wave field. The data were obtained from several distinct ...
Resonant and Near-Resonant Internal Wave Interactions
Publisher: American Meteorological Society
Abstract: The spectral energy density of the internal waves in the open ocean is considered. The Garrett and Munk spectrum and the resonant kinetic equation are used as the main tools of the study. Evaluations of a resonant kinetic ...
On Eddy Viscosity, Energy Cascades, and the Horizontal Resolution of Gridded Satellite Altimeter Products
Publisher: American Meteorological Society
Abstract: otivated by the recent interest in ocean energetics, the widespread use of horizontal eddy viscosity in models, and the promise of high horizontal resolution data from the planned wide-swath satellite altimeter, this paper ...
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 ...
A Microscale View of Mixing and Overturning across the Antarctic Circumpolar Current
Publisher: American Meteorological Society
Abstract: he relative roles of isoneutral stirring by mesoscale eddies and dianeutral stirring by small-scale turbulence in setting the large-scale temperature?salinity relation of the Southern Ocean against the action of the ...
Scaling Turbulent Dissipation in the Transition Layer
Publisher: American Meteorological Society
Abstract: ata from three midlatitude, month-long surveys are examined for evidence of enhanced vertical mixing associated with the transition layer (TL), here defined as the strongly stratified layer that exists between the well ...
Mixing Variability in the Southern Ocean
Publisher: American Meteorological Society
Abstract: key remaining challenge in oceanography is the understanding and parameterization of small-scale mixing. Evidence suggests that topographic features play a significant role in enhancing mixing in the Southern Ocean. This ...
