Stationary mesoscale eddies, upgradient eddy fluxes, and the anisotropy of eddy diffusivity [PDF]
Geophysical Research Letters, 2016 AbstractThe mesoscale eddies of which parameterization is needed in coarse‐resolution ocean models include not only the transient eddies akin to baroclinic instability but also the stationary eddies associated with topography. By applying a modified Lorenz‐type decomposition to the eddy‐permitting Southern Ocean State Estimate, we show that the ...

Mesoscale Eddies Structure Mesopelagic Communities [PDF]
Frontiers in Marine Science, 2020 Mesoscale eddies play a key role in structuring open ocean ecosystems, affecting the entire trophic web from primary producers to large pelagic predators including sharks and elephant seals. Recent advances in the tracking of pelagic predators have revealed that these animals forage in the mesopelagic and the depth and duration of their foraging dives ...

Eddy characteristics in the South Indian Ocean as inferred from surface drifters [PDF]
Ocean Science, 2015 Using a geometric eddy identification method, cyclonic and anticyclonic eddies from submesoscale to mesoscale in the South Indian Ocean (SIO) have been statistically investigated based on 2082 surface drifters from 1979 to 2013.

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

Sub-Mesoscale Frontal Instabilities in the Omani Coastal Current
Mathematics, 2020 The Omani Coastal Current (OCC) flowing northward along the southern coast of Oman during the summer monsoon is associated with an upwelling system. The mesoscale circulation of the western Arabian Sea is dominated by energetic mesoscale eddies down to ...

Seasonal modulation of mesoscale processes alters nutrient availability and plankton communities in the Red Sea [PDF]
, 2019 Hydrographic and atmospheric forcing set fundamental constraints on the biogeochemistry of aquatic ecosystems and manifest in the patterns of nutrient availability and recycling, species composition of communities, trophic dynamics, and ecosystem ...

Comparison between Eulerian diagnostics and finite-size Lyapunov exponents computed from altimetry in the Algerian basin [PDF]
, 2008 Transport and mixing properties of surface currents can be detected from altimetric data by both Eulerian and Lagrangian diagnostics. In contrast with Eulerian diagnostics, Lagrangian tools like the local Lyapunov exponents have the advantage of ...
