Three-Dimensional Structure of Mesoscale Eddies in the Norwegian Coastal Current
Mesoscale Eddies Norwegian Coastal Current Three-Dimensional Structure
2008/12/30
An eddy tracking experiment was carried out in the Norwegian Coastal Current during a 10-day field investigation period in February–March 1986. NOAA satellite infrared data were used in near real time...
Merging of two anticyclonic vortices is studied in the context of a reduced-gravity model and with emphasis on frontal dynamics. Using a particle-in-cell method, numerical experiments illustrate the m...
On the Cylinder Collapse Problem, Mixing, and the Merger of Isolated Eddies
Cylinder Collapse Mixing Merger Isolated Eddies
2008/12/30
The Rossby adjustment of an initially circular column of water, the so-called collapse of a cylinder, continues to be a widely used method for forming lenslike eddies in the laboratory. Here, we consi...
Modeling Studies of Eddies in the Leeuwin Current：The Role of Thermal Forcing
primitive equation Leeuwin Current North West
2008/12/27
A high resolution, multilevel, primitive equation (PE) model is used to investigate the generation and stability of the Leeuwin Current and eddies off the west coast of Australia. Two numerical experi...
Since the pioneering work of Nof, the determination of the westward drift of mesoscale eddies under the planetary (beta) effect has been a recurrent theme in mesoscale oceanography, and several differ...
Geostrophic Turbulence and Emergence of Eddies beyond the Radius of Deformation
Geostrophic Turbulence quasi-geostrophic equation vertical displacements
2008/12/27
Geostrophic turbulence has traditionally been studied within the framework of the classical, quasi-geostrophic equation. This equation, valid only when vertical displacements are weak, possesses a sym...
Westward-propagating SST Anomalies and Baroclinic Eddies in the Sargasso Sea
Baroclinic Eddies Sargasso Sea sea surface temperature
2008/12/24
Previous studies have documented the existence of a zonal band of strong, persistent, westward-propagating sea surface temperature (Ts) anomalies with zonal wavelengths of 800 km and periods of 200 da...
On the Influence of a Lower Layer on the Propagation of Nonlinear Oceanic Eddies
Lower Layer Nonlinear Oceanic Eddies
2008/12/24
The one-layer, reduced-gravity, also called equivalent-barotropic, model has been widely used in countless applications. Although its validity is based on the assumption that a second, lower layer is ...
The analytical results for the splitting conditions of isolated barotropic eddies and the associated final equilibrium state are extended to: 1) nonlinear baroclinic eddies; 2) a group of four nonline...
Heat Transport by Mesoscale Eddies in an Ocean Circulation Model
Heat Transport Mesoscale Eddies Ocean Circulation Model
2008/12/15
The role of mesoscale eddies in the poleward heat transport in the ocean is investigated; in particular, the compensation of poleward eddy heat transport by an eddy-induced mean meridional circulation...
The Formation of Oceanic Eddies in Symmetric and Asymmetric Jets. Part I：Early Time Evolution and Bulk Eddy Transports
Oceanic Eddies Symmetric Asymmetric Jets Bulk Eddy Transports
2008/12/12
A numerical study of the life cycles of eddies formed in perturbed baroclinic jets, emphasizing the influence of spanwise asymmetry in the initial structure of the jet on the downstream evolution of t...
Agulhas Eddies：A Synoptic View Using Geosat ERM Data
Exact Repeat Mission sea surface height Agulhas Eddies
2008/12/11
Warm core rings formed in the, Agulhas Retroflection transfer water from the Indian Ocean to the South Atlantic. In an attempt to measure the strength of this exchange, a combination of satellite alti...
A two-layer model of anticyclonic eddy propagation including the effects of diapycnal mixing is presented. The lower layer is assumed to be of finite volume, whereas the upper layer is infinite in hor...

Coherence Maps Geostrophic Eddies atmospheric forcing
2008/12/11
The theory of stochastic atmospheric forcing of quasigeostrophic eddies is applied to calculate coherence maps, that is, the coherence between the oceanic response at one location and the atmospheric ...
Beta-Induced Translation of Strong Isolated Eddies
Beta-Induced Translation Strong Isolated Eddies
2008/12/10
Strong eddies on the β plane are considered within the framework of the one-layer primitive equations. The attention is focused on calculating the β-induced changes to the spatial structure of the edd...
