Global observations of nonlinear mesoscale eddies

Progress in Oceanography, 2011
Abstract 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 ...

Modeling mesoscale eddies

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, 1990
Abstract 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, 2014
Spinning 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, 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

Optimizing Scrum Mesoscale Eddy Forecasts

1999
Abstract : 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-
