Effect of Fluorine on the Stability of Dense Hydrous Mg Silicates With Implications for the Deep Water Cycle

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Water is believed to be transported, at least locally, into the Earth's deep mantle via hydrous minerals. Fluorine not only tends to interact with water but also influences the stability of hydrous minerals. Thus, knowledge of its stability could be important in understanding the deep‐water cycle.

Impact of Heterogeneous Mantle Viscosity on the Glacial Isostatic Adjustment Correction for GRACE(‐FO): Implications for Surface Mass Trends

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Accurate interpretation of time‐variable gravity from GRACE (‐FO) requires correction for glacial isostatic adjustment (GIA), which has a gravitational signal similar in magnitude to that of contemporary hydrological and cryospheric mass change.

Spin Transition of Ferric Iron in Silicate Glasses Inferred by High‐Pressure Electrical Conductivity Measurements

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Silicate melt has been proposed to exist near the base of the mantle and has been invoked to explain seismic and electrical conductivity anomalies observed near the core‐mantle boundary; however, its presence and stability under lowermost‐mantle conditions remain uncertain.

Structural Evolution of Antigorite by High‐Velocity Impacts

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Serpentine is a major hydrous mineral present in hydrous asteroids that have evolved through planetary impacts. Understanding its dynamic behavior is essential to elucidate the redistribution and retention of water during high‐velocity impact processes. The shock response of antigorite was examined at pressures up to 106 GPa using laser‐driven

Characteristics of a Multi‐Model Ensemble of Mock‐Walker Simulations

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract The Radiative‐Convective Equilibrium Model Intercomparison Project (RCEMIP) phase I provided insights into the tropical radiative‐convective equilibrium state across an unprecedented ensemble of models that includes both those with parameterized and explicit convection.

High‐pressure and high‐temperature polymorphism of Na2CO3 up to 10 GPa

Acta Crystallographica Section B, Volume 82, Issue 4, Page 410-415, August 2026.
Two new high‐pressure phases, ϵ and ϵ‐II, observed during in situ experiments, complete the high‐pressure phase diagram of Na2CO3 and show that both the incommensurate γ phase and the ϵ phase are stable over a wider pressure–temperature range under mantle‐relevant conditions.We report two new high‐pressure polymorphs of sodium carbonate, ϵ and ϵ‐II ...

Mapping structure–property relationships in a 6‐oxo‐verdazyl radical by variable pressure crystallography and density functional theory

Acta Crystallographica Section B, Volume 82, Issue 4, Page 416-432, August 2026.
For the first time, the structural response to pressure of a verdazyl radical crystal has been studied. Computational modelling revealed changes in electronic and magnetic properties as a result of a structural phase transition.The response of the 1,5‐tolyl‐3‐phenyl‐6‐oxo‐verdazyl radical (pTolOV) to pressure in the crystalline state has been ...

Analysis of the Charge Structure and Lightning Activity During a Severe Beijing Thunderstorm via an Innovative Balloon‐Borne 3D Electric Field Observation System

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract We developed an innovative balloon‐borne observation system based on China's BeiDou sounding platform that integrates a three‐axis electric field sensor for in‐cloud measurements of thunderstorm electrification. On 13 May 2025, this system was deployed during a severe convective storm over Beijing. In combination with multisource observations,

Linking Interregional NASA Airborne Observations of Near‐Storm Environments to Tropical Oceanic Convective Structure

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Deep tropical oceanic convection is a key component of the tropical atmosphere, with environmental moisture and vertical wind shear influencing its structure and intensity. However, attempts to generalize convection‐environment relationships across the broad‐scale tropics have produced inconsistent results, partly owing to limits of reanalysis,
