On a Recent Parameterization of Mesoscale Eddies

Journal of Physical Oceanography, 1996
Abstract 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 due to eddies flattens isopycnals as in baroclinic instability but implicitly assumes purely viscous dissipation of the available potential ...

Mesoscale eddies of the Arctic Ocean

Journal of Geophysical Research: Oceans, 1985
Subsurface baroclinic eddies in the Arctic Ocean have a diameter of 10–20 km and are confined in depth between 50 and 300m. During the Arctic Ice Dynamics Joint Experiment (AIDJEX) in the central Beaufort Sea between March 1975 and May 1976, extensive information on eddy characteristics, statistics, and behavior was collected from four manned drifting ...

Mesoscale Eddies in Wake of Islands

Journal of the Atmospheric Sciences, 1965
Abstract The properties of mesoscale eddies in the wake of islands are investigated in the light of their apparent resemblance to the Karman vortex-street pattern. By use of the theoretical results from drag theory and the observed quantities such as cross-stream diameter of the obstacle, wind speed and the dimensions of the pattern, estimates are made

Ocean Eddies and Mesoscale Variability

2017
This chapter presents a review of the advances in observing the ocean eddy field with satellite altimetry over the last 10 years and addresses the techniques being used to study the finer-scale ocean dynamics. It provides an overview of the reprocessing of along-track data, both from conventional altimetry and the new technology missions, and looks at ...

ENERGETICS OF THE GLOBAL OCEAN: THE ROLE OF MESOSCALE EDDIES [PDF]

, 2015
This article reviews the energy cycle of the global ocean circulation, focusing on the role of baroclinic mesoscale eddies. Two of the important effects of mesoscale eddies are: (i) the flattening of the slope of large-scale isopycnal surfaces by the eddy-induced overturning circulation, the basis for the Gent–McWilliams parametrization; and (ii) the ...

Wind/stress feedback to mesoscale ocean eddies

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
Ocean-surface turbulent fluxes (stress and latent heat) are generated by atmospheric instability caused both by wind shear (difference between wind and current) and buoyancy (vertical density stratification). Stress depends on the vector difference between wind and current.

Dynamic Model of Mesoscale Eddies

Geophysical & Astrophysical Fluid Dynamics, 2003
Oceanic mesoscale eddies which are analogs of well known synoptic eddies (cyclones and anticyclones), are studied on the basis of the turbulence model originated by Dubovikov (Dubovikov, M.S., "Dynamical model of turbulent eddies", Int. J. Mod. Phys. B7, 4631-4645 (1993).) and further developed by Canuto and Dubovikov (Canuto, V.M. and Dubovikov, M.S.,

Mesoscale ocean features: Eddies

2010
One of the earliest impacts of satellite data in mainstream oceanography, persuading marine scientists nearly four decades ago that here was a potentially useful new tool, was to reveal the ubiquitous occurrence of mesoscale variability in the open ocean.
