The Statistics and Sensitivity of a Double-Gyre Model: The Reduced-Gravity, Quasigeostrophic Case
Publisher: American Meteorological Society
Abstract: The sensitivity of the time-averaged circulation of an oceanic double-gyre model to variations in the model's parameters and forcing is studied. Unresolved low-frequency variability in the solution leads to statistical ...
Rossby Wave Generation by Poleward Propagating Kelvin Waves: The Midlatitude Quasigeostrophic Approximation
Publisher: American Meteorological Society
Abstract: The phenomenon of Rossby wave generation by poleward propagating baroclinic coastal Kelvin waves is discussed in the low-frequency quasigeostrophic (QG) limit. The response of the system is divided into three frequency ...
A Note on the Reflection of Low-Frequency Equatorial Rossby Waves from Realistic Western Boundaries
Publisher: American Meteorological Society
Abstract: The analytic theory of Cane and Gent on the reflection of low-frequency equatorial waves from arbitrary boundaries is applied to the reflection of long Rossby waves from realistic approximations to the western boundaries ...
A Quantitative Analysis of the Dissipation Inherent in Semi-Lagrangian Advection
Publisher: American Meteorological Society
Abstract: Semi-Lagrangian advection schemes are known to be dissipative because of the interpolation required to estimate the values of the flow fields at each parcel's departure point. In this study, the amplification factors of ...
Phenomenology of the Low-Frequency Variability in a Reduced-Gravity, Quasigeostrophic Double-Gyre Model
Publisher: American Meteorological Society
Abstract: The low-frequency variability of the oceanic wind-driven circulation is investigated by use of a reduced-gravity, quasigeostrophic model with slight variations on the classic double-gyre wind forcing. Approximately 30 ...
