Suppression of Mesoscale Eddy Mixing by Topographic PV Gradients [PDF]

Oceanic mesoscale eddy mixing plays a crucial role in Earth’s climate system by redistributing heat, salt, and carbon. For many ocean and climate models, mesoscale eddies still need to be parameterized. This is often done via an eddy diffusivity K, which

Global Estimation of the Eddy Kinetic Energy Dissipation From a Diagnostic Energy Balance

Geophysical Research Letters, 2023
Mesoscale eddies dominate the ocean kinetic energy reservoir. However, how and where this energy flows out from the mesoscale remains uncertain. Here, a simplified mesoscale energy budget is used where sources due to baroclinic instability are balanced ...

Mesoscale Eddy Kinetic Energy budgets and transfers between vertical modes in the Agulhas Current

, 2022
Western boundary currents are hotspots of mesoscale variability and eddy-topography interactions, which channel energy toward smaller scales and eventually down to dissipation. Here, we assess the main mesoscale eddies energy sinks in the Agulhas Current

Quantifying the Role of Mesoscale-Driven Processes of Nitrate Supply Within an Iceland Basin Eddy Dipole

, 2011
This study quantitatively assesses the mesoscale spatial variability in local nitrate transport and the net nitrate flux associated with an open ocean eddy dipole, using novel data from the SUV?6 ultra?violet (UV) nitrate sensor integrated with SeaSoar ...

Combined physical and biogeochemical assessment of mesoscale eddy parameterisations in ocean models: eddy induced advection at non-eddying resolutions

, 2023
International audienceOcean components of Earth System Models employed for climate projections do not routinely resolve mesoscale eddies for computational cost reasons, and the associated subgrid processes are still parameterised.

The Mesoscale SST–Wind Coupling Characteristics in the Yellow Sea and East China Sea Based on Satellite Data and Their Feedback Effects on the Ocean

Journal of Marine Science and Engineering
The mesoscale interaction between sea surface temperature (SST) and wind is a crucial factor influencing oceanic and atmospheric conditions. To investigate the mesoscale coupling characteristics of the Yellow Sea and East China Sea, we applied a locally ...

Large eddy simulation of ocean mesoscale eddies

Mesoscale eddies produce lateral (2D) fluxes that need to be parameterized in eddy-permitting (1/4-degree) global ocean models due to insufficient horizontal resolution. Here, we systematically apply methods from the 3D LES community to parameterize lateral vorticity fluxes produced by mesoscale eddies leveraging an explicit filtering approach together

Shear enhanced nutrient supply at the Mesoscale

, 2010
Phytoplankton live almost exclusively in the sunlit waters of the euphotic zone. However, in addition to sunlight, phytoplankton require a regular supply of nutrients to grow.

26 years of mesoscale ocean eddy dataset in the Lofoten Basin from Satellite Altimetry

, 2020
The detection of eddies in the Lofoten Basin from daily satellite altimeter data for the 26 year time period (1993-2018) is done using the automated hybrid algorithm described by Halo (2012).

A visible record of eddies in the southern Mozambique Channel [PDF]

, 2003
The flows around Madagascar feed into the Agulhas Current, but there have been few hydrographic studies of the flow within the Mozambique Channel. Some cruise and altimetric data point to this being a region of high mesoscale activity, with eddies ...
