Mesoscale Eddies Enhance the Air‐Sea CO2 Sink in the South Atlantic Ocean

Geophysical Research Letters, 2023
Mesoscale eddies are abundant in the global oceans and known to affect oceanic and atmospheric conditions. Understanding their cumulative impact on the air‐sea carbon dioxide (CO2) flux may have significant implications for the ocean carbon sink ...

How well mesoscale eddies are represented in oceanic models? [PDF]

, 2021
International audienceThe aim of this work is to assess the impact of data assimilation on the dynamics of mesoscale eddies. We do this based on the use of a recent mathematical method from nonlinear dynamics field that is capable of detecting Lagrangian

Understanding Drought‐Induced Soil Moisture Feedback on Atmospheric Circulation: Observations and Simulation Experiments of the 2020 Western U.S. Drought

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract This study examines the large‐scale atmospheric response to reduced evapotranspiration during droughts in the Western U.S., using an observation‐based regression method and numerical experiments with a global climate model. We found that Western U.S.

Dynamic Versus Diabatic Controls on Atmospheric Variability in a Tropical Aquachannel

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Synoptic‐ to planetary‐scale atmospheric variability in the tropics is a potential source of predictability worldwide. However, current weather prediction models struggle to fully capture this variability. Here, we conduct tropical aquachannel simulations using the ICOsahedral Nonhydrostatic model with horizontal grid spacings of 13 and 5 km ...

Substantial Diel Changes of Cloud Adjustments to Aerosols in Ship‐Tracks

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Clouds adjust their albedo, amount and liquid water path to anthropogenic aerosols, and produce a climate forcing. Such cloud adjustments are complex functions of both environmental conditions and interaction time. However, direct observations of temporal changes in cloud adjustments are limited. Here, we develop a method to show observational

Life cycle of mesoscale eddies in the Gulf of Aden

, 2020
International audienceThe Red Sea Water is a warm and salty water produced in the Red Sea by evaporation induced by strong solar radiation. This dense water mass exits the Red Sea through the Strait of Bab El Mandeb, and enters the Gulf of Aden as a ...

Sargassum spp. accumulation and transport by mesoscale eddies [PDF]

Ocean Science
The proliferation of pelagic Sargassum spp. (Sargassum) in the tropical Atlantic has significant ecological and socioeconomic impacts. While large-scale ocean circulation patterns influence the basin-scale distribution of Sargassum, the role of mesoscale

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

A data-driven investigation into the behaviour and parameterisation of mesoscale eddies

, 2021
Mesoscale eddies, turbulent oceanic features of length-scales 10-100km, are an important component of the climate system. They impact the large-scale circulation of both the ocean and atmosphere, as well as the transport of tracers such as heat and ...

Asymmetric Ocean‐Atmosphere Coupling Between Southeast Pacific and Southern Ocean Cooling Through Circulation and Sea‐Ice Changes

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Recent decades have seen persistent sea surface temperature (SST) cooling in the Southeast Pacific (SEP) and Southern Ocean (SO), contrasting with broad ocean warming expected under anthropogenic forcing. Using an interpretable machine‐learning attribution framework applied to multi‐source observations and reanalyses, we focus on monthly SST ...
