Structure and Propagation of Mesoscale Cyclonic Eddies in the Brazil–Malvinas Confluence

International Journal of Climatology, Volume 46, Issue 13, 15 November 2026.
Between 1993 and 2022, 1386 cyclonic eddies were identified in the Brazil–Malvinas Confluence, one of the most energetic regions of the South Atlantic. While most eddies dissipated locally, a smaller number of individuals, more energetic, and longer lived propagated predominantly south‐westward and north‐eastward, driven by topographic constraints and ...

Regional Pathways and Impacts of Greenland Ice Sheet Meltwater Simulated in a Sea Ice‒Ocean Model

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract Much attention has been paid to the recent increase in freshwater supply from the Greenland Ice Sheet (GrIS). We conducted numerical experiments using a sea ice–ocean model with a nominal 0.25° resolution to investigate pathways of GrIS meltwater and its effects on the surrounding sea‐ice and ocean fields.

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

Evolution of Air‐Sea Fluxes in Modeled Long‐Lived Mesoscale Eddies in the South Atlantic Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract Mesoscale eddies modify physical and biogeochemical properties, facilitating the exchange of heat and CO2 between the surface, mixed‐layer and ocean interior. Most state‐of‐the‐art Earth System Models fail to resolve mesoscale processes O $O$(10–100 km) due to computational constraints, thus contributing to uncertainties in current and future ...

On the Differential Conditioning of Sub‐Antarctic Mode Water and Antarctic Intermediate Water Over Decadal Time Scales

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract We report results from a meridional transect performed along 150°W, 30°S to 60°S in the Southern Ocean (SO). This study aimed to document the rates of conditioning of Subantarctic Mode Water (SAMW) and Antarctic Intermediate Water (AAIW), which are formed during deep mixing events in the austral winter.

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

The Oceanic Eddy Heat Transport

, 2002
The rectified eddy heat transport is calculated from a global high resolution ocean general circulation model. The eddy heat transport is found to be strong in the western boundary currents, the Antarctic Circumpolar Current, and the equatorial region ...

Shallow Cumulus Cloud Statistics in Real‐Case Large‐Eddy Simulations and Their Dependence on Soil Moisture

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 11, November 2026.
Abstract The ability of weather and climate models to reproduce the statistical properties of shallow cumulus clouds (SCCs) is critical for representing boundary‐layer transport, cloud cover, and cloud‐radiative effects. This study investigates statistical properties of SCC ensembles using the Icosahedral Nonhydrostatic model in large‐eddy simulation ...

ENERGETICS OF THE GLOBAL OCEAN: THE ROLE OF MESOSCALE EDDIES [PDF]

, 2015
This article reviews the energy cycle of the global ocean circulation, focusing on the role of baroclinic mesoscale eddies. Two of the important effects of mesoscale eddies are: (i) the flattening of the slope of large-scale isopycnal surfaces by the eddy-induced overturning circulation, the basis for the Gent–McWilliams parametrization; and (ii) the ...
