3D Atmospheric Imprint of Mesoscale Eddies Driven by the Thermal Feedback in the Gulf Stream Region

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract The 3D imprint of mesoscale ocean eddies on the overlying atmosphere is investigated using coupled ocean‐atmosphere high‐resolution simulation of the Gulf Stream region, distinguishing cyclones and anticyclones. Sea surface temperature (SST) anomalies are predominantly warm for anticyclones and cold for cyclones, driving a Thermal Feedback ...

The evaluation of boundary‐layer turbulence in high‐resolution numerical weather prediction simulations using Doppler lidar

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 780, October 2026 Part A.
A new method compares both kilometer and sub‐kilometre weather model simulations with Doppler lidar observations to assess the representation of boundary‐layer turbulence. While bulk boundary‐layer properties are well represented, vertical velocity variance is strongly underestimated in both simulations.

A Self-Exciting Model of Eddy Formation at Submesoscale

Abstract Ocean eddies are highly dynamic structures marked by frequent splitting and merging events. They exhibit complex spatio-temporal clustering that traditional Poisson models fail to capture. In this paper, a novel spatio-temporal Hawkes process is introduced to model self-exciting eddy fields on the basis of high-frequency ...

Scale dependence of the marine atmospheric boundary‐layer response to ocean surface‐temperature variability in the EUREC4$$ {\mathrm{EUREC}}^4 $$A region

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 780, October 2026 Part A.
With a minimal physics model and a high‐resolution fully 3D simulation, we demonstrate that the marine atmospheric boundary layer (MABL) response to sea‐surface temperature (SST) variability displays a dependence on the horizontal scales of motion.

Improved statistics of submesoscale eddies in the Baltic Sea retrieved from SAR imagery

, 2016
peer reviewedIn the present paper the spatio-temporal distribution of submesoscale eddies seen in Envisat Advanced Synthetic Aperture Radar (ASAR) imagery of the Baltic Sea is discussed. A total of 1250 ASAR images acquired between 2009 and 2011 form the

Deep Learning‐Based Statistical Downscaling of Sea Surface Temperature Using a Residual Corrective Neural Network

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract The large‐scale oceanic and atmospheric forecasts provided by global climate models typically lack sufficient resolution to accurately capture the response of the coastal ocean to atmospheric forcing and coastal circulation that drive fine‐scale sea surface temperature (SST) variability.

Residence Time of Lagrangian Profiling Floats: Observational Assessment and Numerical Simulation of Station Keeping Ability

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract Autonomous profiling floats have revolutionized global ocean observation, yet their passive drift limits their ability to remain within desired regions. Using observations and simulations with numerical ocean models, we quantify observed and potential residence time (RT) of profiling floats and explore station‐keeping strategies.

Seasonality in submesoscale turbulence [PDF]

, 2014
Although the strongest ocean surface currents occur at horizontal scales of order 100 km, recent numerical simulations suggest that flows smaller than these mesoscale eddies can achieve important vertical transports in the upper ocean. These submesoscale

Microbial Respiration Across Subtropical Eddies: Submesoscale Variability and Biogeochemical Drivers

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Island‐induced eddies from the Canary Islands region propagate southwestward along the Canary Eddy Corridor, exporting biological and biogeochemical properties to the oligotrophic open ocean. However, their contribution to organic matter remineralization, and consequently to the biological carbon pump, throughout their life cycle remains ...

From Surface to Depth: SWOT Altimetry and Glider Observations of a Cuddy in the Northeast Pacific

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract California Undercurrent Eddies (Cuddies) transport heat, salt, and biogeochemical properties from coastal regions to the open Northeast Pacific, but their three‐dimensional structure, lateral exchange mechanisms and complete life‐cycle are still not fully understood.
