Slab Dehydration Observed Down to Lower Seismicity Plane Depths in the Northern Chile Subduction Zone

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract We present a high‐resolution local earthquake tomography model that constrains the distribution of hydration and dehydration processes within the subducting Nazca slab beneath Northern Chile. We image a distinct downdip transition from high Vp/Vs (∼1.75) over low Vp/Vs (∼1.65) to a homogeneously high Vp/Vs slab at depths of ≥ ${\ge} $85 km ...

Classification of the Atmospheric Boundary Layer Based on Turbulent Kinetic Energy Budget Terms Using Machine‐Learning Methods

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The atmospheric boundary layer (ABL) controls surface‐atmosphere exchanges, yet accurately capturing its full complexity, particularly the dynamically evolving nature of turbulence across diverse weather conditions, remains a formidable challenge for traditional classification methods.

Improved Simulation of Seasonal Variation of Arctic Low Clouds by Resolving Subgrid Open Water Fluxes to the Atmosphere in CESM2

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Open water in sea ice significantly influences Arctic low‐cloud formation. However, current global climate models (GCMs), constrained by grid‐scale coupling between the atmosphere and surface components, cannot resolve subgrid heat fluxes and clouds contrasts between open water and sea ice, contributing to biases in Arctic low‐cloud ...
