On Spectral Analysis of Mesoscale Eddies. Part I: Linear Analysis
Publisher: American Meteorological Society
Abstract: his study aims to understand the ocean?s circulation, which is characterized by the presence of multiple alternating zonal jets and transient mesoscale eddies, by systematic analysis of the underlying linear dynamics of ...
On Spectral Analysis of Mesoscale Eddies. Part II: Nonlinear Analysis
Publisher: American Meteorological Society
Abstract: everal turbulent flow regimes of an idealized ocean circulation model are systematically analyzed in physical and spectral domains. Zonal dispersion properties of transient mesoscale eddies are described by the zonal ...
The Dynamics of a Simple Baroclinic Model of the Wind-Driven Circulation
Publisher: American Meteorological Society
Abstract: The authors study the dynamics of a two-layer approximation to the steadily forced baroclinic circulation in a closed ocean basin with the aim of understanding its temporal variability and the onset of low-frequency ...
A Model of Multiple Zonal Jets in the Oceans: Dynamical and Kinematical Analysis
Publisher: American Meteorological Society
Abstract: Multiple alternating zonal jets observed in the ocean are studied with an idealized quasigeostrophic zonal-channel model, with the supercritical, zonal background flow imposed. Both eastward and westward background flows ...
The Turbulent Oscillator: A Mechanism of Low-Frequency Variability of the Wind-Driven Ocean Gyres
Publisher: American Meteorological Society
Abstract: Intrinsic low-frequency variability is studied in the idealized, quasigeostrophic, midlatitude, wind-driven ocean gyres operating at large Reynolds number. A robust decadal variability mode driven by the transient mesoscale ...
Ocean Eddy Dynamics in a Coupled Ocean–Atmosphere Model
Publisher: American Meteorological Society
Abstract: The role of mesoscale oceanic eddies is analyzed in a quasigeostrophic coupled ocean?atmosphere model operating at a large Reynolds number. The model dynamics are characterized by decadal variability that involves nonlinear ...
Dynamical Origin of Low-Frequency Variability in a Highly Nonlinear Midlatitude Coupled Model
Publisher: American Meteorological Society
Abstract: A novel mechanism of decadal midlatitude coupled variability, which crucially depends on the nonlinear dynamics of both the atmosphere and the ocean, is presented. The coupled model studied involves quasigeostrophic ...
