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/).

Inferring tracer diffusivity from coherent mesoscale eddies

Journal of Advances in Modeling Earth Systems, 2023
AbstractMixing along isopycnals plays an important role in the transport and uptake of oceanic tracers. Isopycnal mixing is commonly quantified by a tracer diffusivity. Previous studies have estimated the tracer diffusivity using the rate of dispersion of surface drifters, subsurface floats, or numerical particles advected by satellite‐derived velocity

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 ...

Sensitivity study of energy transfer between mesoscale eddies and wind-induced near-inertial oscillations [PDF]

Ocean Science
Analyses of current observations and numerical simulations at two moorings in the northern South China Sea reveal the transfer of near-inertial energy between the background currents associated with mesoscale eddies and near-inertial currents (NICs).

Observing mesoscale eddy effects on mode-water subduction and transport in the North Pacific. [PDF]

, 2016
While modelling studies suggest that mesoscale eddies strengthen the subduction of mode waters, this eddy effect has never been observed in the field.

Could the two anticyclonic eddies during winter 2003/2004 be reproduced and predicted in the northern South China Sea? [PDF]

Ocean Science, 2019
Great progress has been made in understanding the mesoscale eddies and their role on the large-scale structure and circulation of the oceans. However, many questions still remain to be resolved, especially with regard to the reproductivity and ...

Oceanic three-dimensional Lagrangian Coherent Structures: A study of a mesoscale eddy in the Benguela ocean region [PDF]

, 2012
We study three dimensional oceanic Lagrangian Coherent Structures (LCSs) in the Benguela region, as obtained from an output of the ROMS model. To do that we first compute Finite-Size Lyapunov exponent (FSLE) fields in the region volume, characterizing ...
