Regional‐to‐Global Tectonic and Trench‐Morphology Effects of Oceanic Plateau Subduction

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Regional geodynamic modeling has shown that oceanic plateau subduction can modify the slab behavior. However, few studies have explored these interactions beyond 100 Myr in 3‐D spherical models. Using 3‐D spherical mantle convection models with self‐consistent plate‐like behavior, we investigate how the geometry and rheological properties of ...

Foreshock Migration Preceding the 2025 Mw 8.8 Kamchatka Earthquake: Insights From Single‐Station Observations

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract We investigate the spatiotemporal evolution of foreshocks preceding the 2025 Mw 8.8 Kamchatka earthquake by applying single‐station analysis to waveforms recorded at the nearest seismic station. Our results reveal a southwestward migration of foreshocks toward the mainshock epicenter through multiple stages, with a migration speed of ∼7.0 km ...

Depositional and stratigraphic evolution of a Permian megalake system: Implications for seiche‐influenced models

open access: yesThe Depositional Record, Volume 12, Issue 2, April 2026.
During the Late Permian, the rise of the Gondwanides Belt trapped marine waters, giving birth to a vast megalake. This lake shifted between overfilled, balanced‐fill and underfilled stages that are recorded by high‐frequency accommodation changes, while meteorological seiches shaped the sedimentary dynamic and produced heterolithic beds.

Application of High‐Order Direct Flux Reconstruction and Stiffness‐Resilient Time Integration to Simulations of Idealized Atmospheric Flows

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 4, Page 448-468, April 2026.
The proposed work implements a direct flux reconstruction method for spatial discretization and a stiffness‐resilient exponential time integration method for temporal discretization on the cube‐sphere grid. A space‐time tensor formalism is employed to provide a general representation in any curvilinear coordinate system. This combination enables highly

Increasing Population and Cropland Exposure to Human‐Induced Sequential Heatwave‐Downpour Events

open access: yesEarth's Future, Volume 14, Issue 4, April 2026.
Abstract Compound sequential heatwave‐downpour (SHD) events, characterized by abrupt shifts from heatwaves to heavy rainfall, pose serious threats to health, infrastructure, and agriculture. However, the anthropogenic influence on the increasing trend of SHD events is poorly understood, and projections also exhibit large uncertainties.

Imputing Missing Long‐Term Spatiotemporal Multivariate Atmospheric Data With CNN‐Transformer Machine Learning

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Continuous physical domains are important for scientific investigations of dynamical processes in the atmosphere. However, missing data—arising from operational constraints and adverse environmental conditions—pose significant challenges to accurate analysis and modeling.

Application of Variational Autoencoder‐Based Clustering for Geophysical Fluid Circulations With Small Sample Size

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract The variational autoencoder (VAE), a deep generative model, can extract a good feature representation for clustering from complex data; however, the use of this algorithm in the geophysical fluid circulation has been limited. The sample size for a geophysical phenomenon is generally small because of a large dimensional size, especially for ...
