Dynamics of the Upper Oceanic Layers in Terms of Surface Quasigeostrophy Theory
Publisher: American Meteorological Society
Abstract: In this study, the relation between the interior and the surface dynamics for nonlinear baroclinically unstable flows is examined using the concepts of potential vorticity. First, it is demonstrated that baroclinic unstable ...
Diffusivity, Kinetic Energy Dissipation, and Closure Theories for the Poleward Eddy Heat Flux
Publisher: American Meteorological Society
Abstract: Diffusive eddy closure theory for estimating the poleward heat flux is reexamined and tested in the context of a two-layer homogeneous model. Consideration of the inverse energy cascade induced by baroclinic turbulence on ...
The Role of Moisture in the Dynamics and Energetics of Turbulent Baroclinic Eddies
Publisher: American Meteorological Society
Abstract: The effects of moisture on nonlinear baroclinic eddies are examined in the context of a horizontally homogeneous two-layer quasigeostrophic model. Using an explicit equation for moisture and a simple parameterization of ...
Response of Surface Wind Divergence to Mesoscale SST Anomalies under Different Wind Conditions
Publisher: American Meteorological Society
Abstract: AbstractThe response of the atmospheric boundary layer to mesoscale sea surface temperature (SST) is often characterized by a link between wind stress divergence and downwind SST gradients. In this study, an idealized ...
Storm Track Response to Oceanic Eddies in Idealized Atmospheric Simulations
Publisher: American Meteorological Society
Abstract: Large-scale oceanic fronts, such as in western boundary currents, have been shown to play an important role in the dynamics of atmospheric storm tracks. Little is known about the influence of mesoscale oceanic eddies on ...
