Scale‐Awareness in an Eddy Energy Constrained Mesoscale Eddy Parameterization

Journal of Advances in Modeling Earth Systems, 2023
AbstractThere is an increasing interest in mesoscale eddy parameterizations that are scale‐aware, normally interpreted to mean that a parameterization does not require parameter recalibration as the model resolution changes. Here we examine whether Gent–McWilliams (GM) based version of GEOMETRIC, a mesoscale eddy parameterization that is constrained by

Temporally Varying Mesoscale Eddy Characteristics in the California Current System Identified from RAFOS Floats

Ocean and Coastal Research, 2022
The SOund Fixing And Ranging (RAFOS) floats were deployed by the Naval Postgraduate School (NPS) near California coast from 1992 to 2004 at depth between 150 and 600 m (http://www.oc.nps.edu/npsRAFOS/).

Mesoscale Eddy Properties in Four Major Western Boundary Current Regions

Remote Sensing
Oceanic mesoscale eddies are a kind of typical geostrophic dynamic process which can cause vertical movement in water bodies, thereby changing the temperature, salinity, density, and chlorophyll concentration of the surface water in the eddy.

Submesoscale Instabilities in Mesoscale Eddies [PDF]

Journal of Physical Oceanography, 2017
AbstractSubmesoscale processes have been extensively studied in observations and simulations of fronts. Recent idealized simulations show that submesoscale instabilities also occur in baroclinic mesoscale cyclones and anticyclones. The instabilities in the anticyclone grow faster and at coarser grid resolution than in the cyclone.

A vortex-implanted initialization scheme for the mesoscale eddy prediction: Idealized experiments

Frontiers in Marine Science, 2022
Mesoscale eddy prediction has been a big challenge to oceanographers and marine environment forecasters. Although the traditional initialization for the prediction, i.e., through assimilating the satellite-derived sea level anomalies (SLA) into a model ...

On the Genesis of the South China Sea Mesoscale Eddies

Journal of Marine Science and Engineering, 2022
The climatology of the mesoscale eddies in the upper layer of the South China Sea (SCS) is investigated for an understanding of its genesis using the outputs from a 1/12.5° ocean reanalysis.

Oceanic Mesoscale Eddies Identification Using B-Spline Surface Fitting Model Based on Along-Track SLA Data

Remote Sensing, 2022
Gridded reanalysis data has been widely used in oceanic mesoscale eddy identification. However, there is little research on identifying oceanic mesoscale eddies based on along-track data.

Dissipation of mesoscale eddies at a western boundary via a direct energy cascade

Scientific Reports, 2022
The fate of mesoscale eddy kinetic energy represents a large source of uncertainty in the global ocean energy budget. Satellite altimetry suggests that mesoscale eddies vanish at ocean western boundaries.

Elastic Interaction Between a Mesoscale Eddy‐Pair and an Axisymmetrical Eddy

Journal of Geophysical Research: Oceans, 2023
AbstractWe investigate numerically the elastic interaction between an eddy‐pair and an axisymmetrical eddy in inviscid isochoric two‐dimensional (2D) flows, as well as in three‐dimensional (3D) flows under the quasi‐geostrophic (QG) approximation. The eddy‐pair is a straight moving Lamb‐Chaplygin dipole where the absolute value of either its positive ...
