DJ4Earth: Differentiable, and Performance‐Portable Earth System Modeling via Program Transformations

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.
Abstract Differentiable Earth system models (ESMs) enable powerful applications such as sensitivity analysis, gradient‐based calibration, state estimation, boundary flux inversions, uncertainty quantification, and online machine learning. Reverse‐mode automatic differentiation (AD) efficiently provides gradients for such tasks, yet models have rarely ...

Existence and asymptotic behavior of beam-equation solutions with strong damping and p(x)-biharmonic operator

, 2022
In this paper, we consider a nonlinear beam equation with a strong damping and the p(x)-biharmonic operator. The exponent p(·) of nonlinearity is a given function satisfying some condition to be specified. Applying Faedo– Galerkin’s method, the existence

Asymmetries in Anticyclone Catalyze Submesoscale Motions

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract 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. Based on a series of high‐resolution numerical experiments, we found that asymmetric anticyclones act as potent catalysts for submesoscale ...

Large Deformation, Pressure‐Driven Mechanistic Modeling of the 2018 Caldera Collapse at Kīlauea Volcano, HI

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Volcanic calderas are large depressions formed by the rapid collapse of overlying rock into a magma chamber during eruptions. We utilize Smoothed Particle Hydrodynamics (SPH), a continuum, meshfree numerical method, to study the 2018 caldera collapse at Kīlauea volcano in Hawaii.

The Energy Exascale Earth System Model Version 3: 2. Overview of the Coupled System

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract The Energy Exascale Earth System Model version 3 (E3SMv3) represents the latest advancement in Earth system modeling developed by the U.S. Department of Energy (DOE). Building upon previous versions, E3SMv3 introduces significant updates across its coupled components to enhance capability and improve fidelity.

Development of a Mesoscale‐ and Tide‐Resolving Ocean–Biogeochemistry Model for the Pacific: Tidal Enhancement of the Biological Carbon Pump

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract This study presents a new physical‐biogeochemical simulation of the Pacific Ocean that resolves mesoscale dynamics and explicitly includes tidal forcing. The primary objective is to develop and document a modeling framework that serves both as a detailed record of model configuration and forcing preparation, and as a reference for future ...

Lorenz Energy Cycle of the Global Eddying Ocean Simulated on Meshes With Different Designs and Resolutions

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract We analyze the Lorenz Energy Cycle of the ocean simulated by FESOM on several unstructured meshes, with nominal horizontal resolution ranging from 1/4 to 1/12°. Some meshes are more strongly refined in regions where the eddy kinetic energy (EKE) is large, whereas others follow a standard design, with resolution gently increasing toward high ...

The Climate Modeling Alliance Atmosphere Dynamical Core: Concepts, Numerics, and Scaling

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract This paper presents the dynamical core of the Climate Modeling Alliance (CliMA) atmosphere model, designed for efficient simulation of a wide range of atmospheric flows across scales. The core uses the nonhydrostatic equations of motion for a deep atmosphere, discretized with a hybrid approach that combines a spectral element method (SEM) in ...
