Mesoscale Eddy Dynamics Over Continental Slopes: a Model Inter-comparison
, 2016 Mesoscale eddies play an important role in transport and mixing processes throughout the global ocean. In many regions these eddies interact strongly with steep bathymetric features such as continental slopes and seamounts, for example in the western and

Towards a mesoscale eddy closure
Ocean Modelling, 2008 Zusammenfassung A turbulence closure for the effect of mesoscale eddies in non-eddy-resolving ocean models is proposed. The closure consists of a prognostic equation for the eddy kinetic energy (EKE) that is integrated as an additional model equation, and a diagnostic relation for an eddy length scale (L), which is given by the minimum of Rhines scale

Ocean Modelling, 2005
Abstract Mesoscale eddies are not resolved in coarse resolution ocean models and must be modeled. They affect both mean momentum and scalars. At present, no generally accepted model exists for the former; in the latter case, mesoscales are modeled with a bolus velocity u ∗ to represent a sink of mean potential energy.

Oceanic mass transport by mesoscale eddies
Science, 2014Spinning up ocean circulation discretely Ocean eddies with diameters of tens to hundreds of kilometers are an important component of water transport on a global scale. Averaged over periods of many years, ocean circulation is regular and coherent enough to have been described as a conveyor belt. However, over shorter time scales,

Illustrative Visualization of Mesoscale Ocean Eddies
Computer Graphics Forum, 2017AbstractFeature‐based time‐varying volume visualization is combined with illustrative visualization to tell the story of how mesoscale ocean eddies form in the Gulf Stream and transport heat and nutrients across the ocean basin. The internal structure of these three‐dimensional eddies and the kinematics with which they move are critical to a full ...

Westward motion of mesoscale eddies
Deep Sea Research Part B. Oceanographic Literature Review, 1990Abstract 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 different formulae have been proposed in the literature.

On the eddy‐Kuroshio interaction: Evolution of the mesoscale eddy
Journal of Geophysical Research: Oceans, 2002Presented are results from a numerical study of the interaction of a mesoscale eddy and the Kuroshio using a high‐resolution regional general circulation model (GCM). The distinct evolution of the mesoscale eddies is not new in the literature, but most of the previous studies were conducted with simpler model configurations.

On a Recent Parameterization of Mesoscale Eddies
Journal of Physical Oceanography, 1996Abstract 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 in Wake of Islands
Journal of the Atmospheric Sciences, 1965Abstract 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
