Investigating the Use of Terrain‐Following Coordinates in AI‐Driven Precipitation Forecasts

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Artificial Intelligence (AI) weather prediction (AIWP) models often produce “blurry” precipitation forecasts. This study presents a novel solution to tackle this problem—integrating terrain‐following coordinates into AIWP models. Forecast experiments are conducted to evaluate the effectiveness of terrain‐following coordinates using FuXi, an ...

Accretion and Differentiation of Vesta and the Mesosiderite Parent Body Inferred From Ni Stable Isotope Compositions

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We present high‐precision Ni stable isotope data for mesosiderites, eucrites, and diogenites to investigate the accretion and differentiation of asteroid 4 Vesta. Ni isotope variations in eucrites and diogenites are dominated by kinetic diffusion and chondritic contamination, rendering them unsuitable for reconstructing Vesta's primitive Ni ...

Creep of Talc at Subduction Zone Conditions: Implications for Slow Slip and Strength of the Lithosphere

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Talc can strongly influence the rheological properties of the subduction interface. Despite geologic evidence for talc at the interface, and proposed links between its rheology and slow slip events, few experiments have been conducted on talc at relevant conditions. We conducted constant‐load shear deformation experiments on talc aggregates at

Second‐Order Degradation Modeling and Multiscale Feature Fusion for High‐Fidelity Segmentation of Low‐Quality Digital Rock Images

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Digital Rock Physics (DRP) is a critical tool for characterizing rock properties and modeling multiphase flow, but segmenting low‐quality (LQ) rock images remains a key challenge due to partial volume blurring. In this study, we propose a method that leverages a second‐order degradation model to generate physically meaningful synthetic LQ and ...

Quantifying Uncertainty in Time Averages of the Geomagnetic Dipole

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Time averages of the geomagnetic field provide insights into the state of the geodynamo, but uncertainties in these averages can compromise the interpretation. An important source of uncertainty is due to a restricted averaging duration. Short averages do not sample the full range of variability, leading to errors in the resulting estimates ...
