Why Are Physics‐Based Models Taking so Long to Run?

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Physics‐based models provide a reliable and interpretable framework based on established physical laws, allowing them to deal with unforeseen future conditions much better than statistical data‐driven methods. Physics‐based models in Earth science (e.g., climate models, hydrological models, and groundwater models) are commonly used for ...

Sensitivity of Nocturnal Low‐Level Jet Representation to Model Resolution and Boundary Layer Schemes: Implications for Wind Energy Assessment Over Saudi Arabia

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract Sensitivity tests on low‐level wind speeds and stability associated with the diurnal cycle of convective boundary layer (CBL) are performed using five Weather Research and Forecasting (WRF) Model simulations over the Riyadh, Saudi Arabia region.

Global Three‐Dimensional Simulation of Magnetospheric Dynamics During the Extreme Geomagnetic Storm of 10–11 May 2024

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study presents a high‐resolution three‐dimensional global magnetohydrodynamic (MHD) simulation of the historic geomagnetic storm of 10–11 May 2024, using observational data for the ACE solar wind input. This extreme event was characterized by intense solar wind dynamic pressure (∼50 nPa) and exceptionally strong interplanetary magnetic ...

Faint Diffuse 557.7‐nm Emissions Equatorward of the Auroral Oval: Conjugate Observations by Ground Airglow Imagers and the Arase Satellite

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract At subauroral latitudes, discrete auroras, such as strong thermal emission velocity enhancement and stable auroral red arcs, have been extensively studied. On the other hand, diffuse emissions at subauroral latitudes have not been studied well.

Variation of Global Ionospheric Scintillation and Its Effect on GPS Kinematic PPP‐AR Performance During Geomagnetic Storms in Solar Cycle 25: A Statistical Analysis

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Enhanced small‐scale ionospheric irregularities during geomagnetic storms can disturb Global Navigation Satellite System (GNSS) carrier‐phase tracking and are associated with reduced stability of ambiguity‐fixed precise point positioning (PPP‐AR), but their impact on kinematic positioning remains insufficiently quantified.

Observational Analysis on the Relationship Between Chorus Waves and MeV Microburst Electron Precipitation

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Microbursts are thought to be a key contributor to radiation belt electron loss, with chorus waves considered a primary driver of this precipitation. However, the conditions under which chorus waves produce MeV electron loss remain poorly constrained.

Field‐Aligned Anisotropy of Electrons in Magnetic Hole Behind the Dipolarization Front in the Flow Braking Region

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Magnetic holes (MHs) are magnetic structures characterized by a depression of magnetic field strength and have been frequently observed around dipolarization fronts (DFs), which are characterized by the increase in the magnetic field Bz. Both MHs and DFs are potential contributors to the formation of electron anisotropy.

Substorm Effects on Chorus Emissions Modulated by ULF Waves

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Although cross‐scale wave‐particle interactions play a critical role in energy transfer in the magnetosphere, the influence of geomagnetic activity on the physical mechanisms involved remains unclear. In this study, we investigate this question by analyzing Van Allen Probes‐A observations of an event occurring on 25 July 2016.

Self‐Oscillation in Photochromic Thiazolothiazole‐Embedded Polymers

Advanced Photonics Research, Volume 7, Issue 9, September 2026.
Experimental observation of redox‐driven self‐oscillations at the soft‐matter/ambient interface of a photochromic thiazolothiazole‐embedded polymer by spectroscopic ellipsometry. The self‐oscillations are facilitated by a reversible electron transfer cycle involving the thiazolothiazole unit, a cross‐linked polymer matrix, and ambient molecular oxygen.
