On the Generation of Mesoscale Eddies and their Contribution to the Oceanic General Circulation. II. A Parameter Study
Mesoscale Eddies Oceanic General Circulation Parameter Study
2009/3/24
In this investigation the wind-driven ocean circulation theories are extended to include mesoscale eddies as an integral part of the general circulation of the ocean. A two-layer numerical model of oc...
On the Generation of Mesoscale Eddies and their Contribution to the Oceanic General Circulation. I. A Preliminary Numerical Experiment
Mesoscale Eddies Oceanic General Circulation Preliminary Numerical Experiment
2009/3/24
Numerical experiments on the wind-driven ocean circulation in a closed basin show that mesoscale eddies can appear spontaneously during the integration of the equations of motion for a baroclinic ocea...
The Role of Mesoscale Eddies in the General Circulation of the Ocean—Numerical Experiments Using a Wind-Driven Quasi-Geostrophic Model
Mesoscale Eddies Ocean—Numerical Experiments General Circulation
2009/2/23
Results from a two-layer, quasi-geostrophic, general circulation model of the ocean with fine horizontal resolution are presented. As in Holland and Lin (1975a.b), mesoscale eddies spontaneously arise...
Horizontal Deflection of Acoustic Paths by Mesoscale Eddies
Horizontal Deflection Acoustic Paths Mesoscale Eddies
2009/2/16
The horizontal angular deflection of a ray path through a circular eddy is roughly 2v, where v is the fractional variation in sound speed at the eddy center; v may reach 0.03 for intense Gulf Stream r...
Simulated Dynamic Balances for Mid-Ocean Mesoscale Eddies
Mid-Ocean Mesoscale Eddies Simulated Dynamic Balances
2009/2/13
Eulerian potential vorticity and heat balances calculated for a multi-layered quasi-geostrophic model are shown to be consistent with those inferred from the MODE data. Above the thermocline the balan...
Mesoscale Eddies Detached from Spatially Growing Meanders in an Eastward-Flowing Oceanic jet Using a Two-Layer Quasi-Geostrophic Model
Mesoscale Eddies Eastward-Flowing Oceanic jet Two-Layer Quasi-Geostrophic Model
2009/2/10
The process of eddy detachment from a strong, eastward-flowing oceanic jet, which is modeled after the Gulf Stream, is studied using a two-layer quasi-geostrophic model. Numerical calculations are per...
A Numerical Study of Nonfrictional Decay of Mesoscale Eddies
Nonfrictional Decay Mesoscale Eddies
2009/2/7
The decay of mesoscale eddies can be attributed to either frictional dissipation of kinetic energy through viscous effects or through dispersive spreading of the different constituent Rossby wave comp...
Poleward Buoyancy Transport in the Ocean and Mesoscale Eddies
Poleward Buoyancy Transport Mesoscale Eddies
2009/1/12
There are many dynamic similarities between mesoscale eddies in the ocean, and cyclones and anticyclones in the earth's atmosphere. Observational data, however, are still not adequate to explore this ...
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...
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...
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...
A recent parameterization of mesoscale eddies by Gent and McWilliams (GMc) represents their effects as advective and diffusive fluxes along isopycnals. The form chosen for the added transport velocity...
