The Vertical Motion of Submesoscale Coherent Vortices across Neutral Surfaces
Submesoscale coherent vortices Neutral Surfaces
2009/1/9
Submesoscale coherent vortices (SCVs, “meddies” or “bullets”) are shown not to move along either potential density surfaces or neutral surfaces, due to the compressibility of sea water being a functio...
Nonlinear Waves and Coherent Vortex Structures in Barotropic β-plane Jets
Nonlinear Waves Barotropic β-plane Jets Coherent Vortex Structures
2009/1/8
We examine the nonlinear evolution of barotropic β-plane jets on a periodic domain with a pseudospectral. A calculation of the linear growth rate yields an infected U-shaped curve on the β versus k0 p...
The Propagation of Submesoscale Coherent Vortices
submesoscale coherent vortex density-weighted
2008/12/12
A combined analytical and numerical examination of submesoscale coherent vortex (SCV) dynamics and propagation is conducted. This study is prompted by observations of the movement relative to their su...
The Formation of Oceanic Eddies in Symmetric and Asymmetric Jets. Part II：Late Time Evolution and Coherent Vortex Formation
quasigeostrophic Late Time Evolution Coherent Vortex Formation Oceanic Eddies
2008/12/10
The dynamical processes involved in eddy genesis, evolution, and demise as revealed in a series of high-resolution numerical simulations of perturbed oceanic jets are investigated. Comparisons are pro...
The Net Advective Effect of a Vertically Sheared Current on a Coherent Vortex
Net Advective Effect Vertically Sheared Current Coherent Vortex
2008/8/12
The nonlinear interaction of a localized vortex with a vertically sheared mean flow has been studied using numerical and asymptotic methods in a multilayer quasigeostrophic model on the beta plane.
Linear Instability of Barotropic Submesoscale Coherent Vortices Observed in the Ocean
Linear Instability Barotropic Submesoscale Coherent Vortices Observed
2008/7/16
The linear instability of circular quasigeostrophic vortices with horizontal cross sections of angular velocity identical to those that fit the observations of submesoscale eddies in the ocean is inve...
Resistance of a Coherent Vortex to a Vertical Shear
Resistance of a Coherent Vortex to a Vertical Shear
2008/6/20
The authors study the splitting of a coherent vortex by a large-scale baroclinic background current. A criterion for the splitting of the vortex is defined, and the process is then studied numerically...
Coherent Eddies in the Labrador Sea Observed from a Mooring
Coherent Eddies Labrador Sea Mooring
2008/6/4
During June–November 1994, a mooring in the central Labrador Sea near the former Ocean Weather Station Bravo recorded a half-dozen anomalous events that prove to be two different types of coherent edd...
Twenty years of spatially coherent deepwater warming in lakes across Europe related to the North Atlantic Oscillation
spatially coherent deepwater across Europe
2014/5/5
Twenty to fifty years of annual mean deepwater (hypolimnetic) temperature data from twelve deep lakes
spaced across Europe (2u959W to 14u09E, 46u279 to 59u009N) show a high degree of coherence among ...
