Near-Surface Atmospheric Response to Meso- and Submesoscale Current and Thermal Feedbacks

International audienceAbstract Current feedback (CFB) and thermal feedback (TFB) have been shown to strongly influence both atmospheric and oceanic dynamics at the oceanic mesoscale (10–250 km). At smaller scales, oceanic submesoscale currents (SMCs; 0.1–

Submesoscale Variability and Basal Melting in Ice Shelf Cavities of the Amundsen Sea

Geophysical Research Letters
Melting of ice shelves can energize a wide range of ocean currents, from three‐dimensional turbulence to relatively large‐scale boundary currents. Here, we conduct high‐resolution simulations of the western Amundsen Sea to show that submesoscale eddies ...

Observations Reveal Intense Air‐Sea Exchanges Over Submesoscale Ocean Front

Geophysical Research Letters
Air‐sea exchanges across oceanic fronts are critical in powering cloud formation, precipitation, and atmospheric storms. Oceanic submesoscale fronts of scales 1–10 km are characterized by strong sea surface temperature (SST) gradients.

Upper Ocean Thermodynamic Response to Coupling Currents to Wind Stress over the Gulf Stream

Journal of Marine Science and Engineering
We use high-resolution coupled atmosphere–ocean model simulations over the Gulf Stream extension region during a winter season to examine the upper ocean thermodynamic response to including current feedback to atmospheric wind stress. We demonstrate that

Detecting submesoscale cold filaments in a basin-scale gyre in large, deep Lake Geneva (Switzerland/France)

Submesoscale filaments are a well-documented feature of oceanic flow fields. Based on the analysis of high-resolution 3D numerical simulations, field observations and remote sensing imagery, this study, carried out in Lake Geneva, Western Europe's ...

Asymmetries in Anticyclone Catalyze Submesoscale Motions

Geophysical Research Letters
Oceanic mesoscale eddies are often asymmetric, exhibiting horizontal deformation and vertical tilt, yet the implications of these structural asymmetries for finer‐scale dynamics remain poorly understood.

Observed rapid adjustment of the atmospheric boundary layer to submesoscale sea surface temperature fronts

Current understanding of the role of ocean variability in air–sea exchange is constrained to large and mesoscale dynamics. Oceanic fronts and filaments with horizontal spatial scales of order 0.1 to 10 km—denoted submesoscale—are ...

Asymmetry of Submesoscale Instabilities in Anticyclonic and Cyclonic Eddies

Geophysical Research Letters
The upper‐ocean relative vorticity has been found to be cyclonically skewed, but altimetry observations indicate that long‐lifespan mesoscale eddies tend to be anticyclonic.
