Cumulative Effect of Synoptic‐Scale Storms on Decadal Mixed‐Layer Temperature Variability in the Mid‐Latitude North Pacific

Geophysical Research Letters
Decadal variability of mixed‐layer temperature (Tm) in the mid‐latitude North Pacific plays a key role in air–sea interactions and regional climate. While previous studies have emphasized the role of large‐scale climate modes in this variability, the ...

Systematic Ocean Ventilation Biases in Climate Models Indicated by Chlorofluorocarbon‐12

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract An accurate representation of ocean ventilation in models is crucial for simulating ocean uptake of heat and carbon, as well as the ocean's supply of oxygen. Using the Inverse Gaussian Transit Time Distribution technique, we assessed ocean ventilation in current climate models via comparing water ages —defined as the time since last contact ...

Spatiotemporal Variability and Large‐Scale Drivers of Storm Surge Extremes on the Northwestern European Shelf

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Extreme Sea Level (ESL) poses a high risk to coastal communities and infrastructure, with its frequency and intensity projected to increase in the future. In this study, we focus on the storm surge component of sea level variability, a key contributor to extreme still water levels during storms.

Quantifying the Energy Input Into the Ocean Due To Tropical Cyclones in the North Atlantic From 1994 to 2015

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract In this study, composites of 207 tropical cyclones (TCs) between 1994 and 2015 are used to examine their impact on the surface and subsurface ocean temperature structure in the North Atlantic Ocean using the Hybrid Coordinate Ocean Model (HYCOM) reanalysis data set.

Design and Implementation of a Data‐Driven Parameterization for Mesoscale Eddy‐Induced Transport: Idealized Two‐Layer Configurations

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract Mesoscale eddies contribute to ocean transport and are a major sink of available potential energy (APE). When unresolved or only partially resolved, their effects must be parameterized to simulate a realistic large‐scale state. Traditionally, this is achieved via the Gent‐McWilliams (GM) parameterization, which represents the eddy‐induced ...

NORi: An ML‐Augmented Ocean Boundary Layer Parameterization

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract NORi is a machine learning (ML) parameterization of ocean boundary layer (BL) turbulence that is physics‐based and augmented with neural networks. NORi stands for neural ordinary differential equations Richardson number (Ri) closure. The physical parameterization is controlled by a Richardson number‐dependent diffusivity and viscosity.

Decadal Coherence of Arctic Thermohaline Staircases

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Thermohaline staircase layers residing above the relatively warm Atlantic Water layer have been consistently observed in the Arctic Ocean for over 50 years. Previous studies demonstrate that these structures exhibit large‐scale spatial coherence.

The Central Role of Labrador Sea Convection in Linking Atmospheric Forcing to the Atlantic Meridional Overturning Circulation and Labrador Current Variability

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The Atlantic Meridional Overturning Circulation (AMOC) and the Labrador Current play central roles in the North Atlantic climate system through their influence on the transport of heat and freshwater and the modulation of regional climate variability.

The Importance and Mechanics of Near‐Seafloor Oxygenation Events in Shallow Coastal Environments

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Bottom‐water oxygen (O2) possibly constitutes the strongest regulating factor on ecosystem function of the seafloor environment. The conventional view of bottom‐water O2 regulation in temperate regions is a strong seasonal variability imposed by deposition of fresh, labile organic carbon following the spring and fall plankton bloom generating ...

Projected Future Changes of Australian Boundary Currents—Insights From Dynamical Downscaling Simulations

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Australian boundary currents strongly influence regional circulation, ecosystems, and coastal environments, yet remain inadequately resolved in coarse‐resolution global climate models, especially along mid‐latitude coasts. To assess their future evolution, we examine boundary‐current changes under an intermediate‐emissions scenario with a 1/12°
