Enhancing the Upper Boundary Layer Damping Scheme for km‐Scale ICON: A Question of Wavelength

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract The upper boundary condition treatment in atmospheric models has a pronounced impact on stability and performance. At the same time, the choice of damping settings can severely impact atmospheric states by not sufficiently preventing back‐reflections of vertically propagating waves from the model top or provoking back‐reflections from the ...

A Model Intercomparison Study of Mixed‐Phase Clouds in a Laboratory Chamber

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract Supercooled liquid water often persists in mixed‐phase clouds for hours to days, even though a simple, well‐mixed Wegener‐Bergeron‐Findeisen model predicts rapid depletion of liquid water in the presence of ice. The persistence is well documented, but the relative importance of the maintaining mechanisms remains uncertain.

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.

Characteristics of Extratropical Cyclones Under Uniform SST Warming and Increased CO2 Forcing in a Global Storm‐Resolving Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract Using the GFDL EXperimental System for High‐resolution prediction on Earth‐to‐Local Domains (X‐SHiELD), a global storm‐resolving atmosphere model with a slab ocean, we examine extratropical cyclone (ETC) responses under three scenarios: 4 K sea surface temperature (SST) warming, increased CO2 concentration, and their combination.

The Role of Bubbles in Air‐Sea Gas Exchange: A Critical Review

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Air‐sea gas exchange regulates the exchange of climatically important gases between the ocean and the atmosphere, shaping both climate and ocean biogeochemistry. Bubbles beneath the sea surface enhance this exchange by introducing an additional transfer pathway in parallel to the interfacial transfer route.
