Coral Reef‐Level Upwelling in an Internal Wave Hotspot Modulated by Mesoscale Dynamics

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Coral reefs in the northern South China Sea experience some of the world’s most energetic internal waves (IWs), yet records of how these dynamics influence reef‐level conditions are rare. Using over 6 years of temperature data from Dongsha Atoll, we show that IWs drive diel temperature fluctuations that reduce subsurface heat exposure and ...

Fractal Dimension of Shallow Cumulus Cloud Boundaries Beyond Bulk Fractal Scaling

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Cloud boundaries reflect turbulent mixing and cloud–environment interactions, but their geometric complexity remains poorly quantified. Here, we investigate the complexity of shallow cumulus cloud edge using two fractal approaches: the bulk area–perimeter method and the individual‐cloud box‐counting method.

An Orthogonal Geometry-Based Algorithm for Accurate Mesoscale Eddy Detection

Journal of Marine Science and Engineering
This article introduces a mesoscale eddy detection algorithm that employs orthogonal transformations of flow field data, and subsequently, for simplicity, it is abbreviated as the OG algorithm.

Boundary‐Aware Separation of Vortical and Wavy Motions in the Ocean

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract With the recent popularity of the tide‐resolving and submesoscale‐admitting numerical simulations, there is an increasing interest in separating vortical and wavy motions in the ocean. The recently‐proposed dynamics‐based decomposition exploits the relative magnitude of the relative vorticity and horizontal divergence in Fourier space and ...

Statistical Analysis of Multi-Year South China Sea Eddies and Exploration of Eddy Classification

Remote Sensing
Mesoscale eddies are structures of seawater motion with horizontal scales of tens to hundreds of kilometers, impact depths of tens to hundreds of meters, and time scales of days to months. This study presents a statistical analysis of mesoscale eddies in

ENSO's Imprint on the Southern Ocean: Wind Waves Drive Surface Cross‐Frontal Flow

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Tropical teleconnection associated with El Niño–Southern Oscillation (ENSO) is widely recognized for regulating multiple physical processes in the Southern Ocean. However, despite its influence on Southern Ocean wind patterns, the response of surface flow has received little attention.

Isopycnal Pathway for Small‐Particle Export in a Decaying Cyclonic Eddy Revealed by a BGC‐Argo Float

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Mesoscale eddies influence carbon export through production, subduction, mixing, and particle redistribution. In this study, a BGC‐Argo float observed a deep particle layer in the twilight zone during the decay of a cyclonic eddy in the Northwest Pacific.

Mesoscale eddies heterogeneously modulate CO₂ fluxes in eddy-rich regions of the Southern Ocean [PDF]

Biogeosciences
Mesoscale eddies are known to influence the Southern Ocean biogeochemistry. However, the distinct contributions of cyclonic and anticyclonic eddies to air–sea CO2 fluxes, as well as their longer-term effects remain poorly studied. We present results from

Asymmetric Particle Aggregation in Ocean Eddies Driven by Eddy‐Wind Interactions

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Mesoscale eddies, prevalent across the global ocean, play a crucial role in the transport and mixing of climate‐sensitive tracers such as heat, salt, and nutrients. While traditional quasi‐geostrophic theory predicts symmetric kinematics and equivalent material transport by cyclonic and anticyclonic eddies, our analysis of satellite altimeter ...

Numerical Models, Observing Systems, and Data Assimilation for Prediction of Ocean Mesoscale Eddies

Ocean-Land-Atmosphere Research
Mesoscale eddies pervade the global ocean, characterized by a typical horizontal scale of approximately 100 km and a timescale on the order of a month.
