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 ...
Nonlinear Cascades of Surface Oceanic Geostrophic Kinetic Energy in the Frequency Domain
Publisher: American Meteorological Society
Abstract: otivated by the ubiquity of time series in oceanic data, the relative lack of studies of geostrophic turbulence in the frequency domain, and the interest in quantifying the contributions of intrinsic nonlinearities to ...
The Role of Rough Topography in Mediating Impacts of Bottom Drag in Eddying Ocean Circulation Models
Publisher: American Meteorological Society
Abstract: otivated by the substantial sensitivity of eddies in two-layer quasigeostrophic (QG) turbulence models to the strength of bottom drag, this study explores the sensitivity of eddies in more realistic ocean general circulation ...
Impact of Parameterized Internal Wave Drag on the Semidiurnal Energy Balance in a Global Ocean Circulation Model
Publisher: American Meteorological Society
Abstract: he effects of a parameterized linear internal wave drag on the semidiurnal barotropic and baroclinic energetics of a realistically forced, three-dimensional global ocean model are analyzed. Although the main purpose of the ...
Geostrophic Turbulence in the Frequency–Wavenumber Domain: Eddy-Driven Low-Frequency Variability
Publisher: American Meteorological Society
Abstract: otivated by the potential of oceanic mesoscale eddies to drive intrinsic low-frequency variability, this paper examines geostrophic turbulence in the frequency?wavenumber domain. Frequency?wavenumber spectra, spectral ...
Geographical Distribution of Diurnal and Semidiurnal Parametric Subharmonic Instability in a Global Ocean Circulation Model
Publisher: American Meteorological Society
Abstract: AbstractThe evidence for, baroclinic energetics of, and geographic distribution of parametric subharmonic instability (PSI) arising from both diurnal and semidiurnal tides in a global ocean general circulation model is ...
