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.

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.

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,

Towards a mesoscale eddy closure
Ocean Modelling, 2008Zusammenfassung 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

Optimizing Scrum Mesoscale Eddy Forecasts
1999Abstract : Our long term technical goal is to produce a tested adjoint for ROMS (the Regional Ocean Modeling System, descended from SCRUM) that is suitable for general use by ROMS modelers. This is complementary to the Kalman Filter, ESSE, and Singular Vector techniques being developed by Rutgers, Harvard and University of Colorado scientists. Our long-

Universal Mathematical Model of Mesoscale Eddy
2021Starting from the movement of Lagrangian particles, a universal nonlinear dynamics model of mesoscale eddies is established. The properties of the model are explained.

Ocean Eddies and Mesoscale Variability
2017This 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 ...

1991
Abstract : The objectives of this grant comprised investigations of oceanic geostrophic turbulence and another mesoscale processes related to eddies and fronts, a numerical study of internal tides, and the organization of an international colloquium on oceanic vortices.

Mesoscale ocean features: Eddies
2010One 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.

Global observations of nonlinear mesoscale eddies
Progress in Oceanography, 2011Abstract Sixteen years of sea-surface height (SSH) fields constructed by merging the measurements from two simultaneously operating altimeters are analyzed to investigate mesoscale variability in the global ocean. The prevalence of coherent mesoscale features (referred to here as “eddies”) with radius scales of O(100 km) is readily apparent in these ...
