Major Space Weather Risks Identified via Coupled Physics‐Engineering‐Economic Modeling
AGU Advances, Volume 7, Issue 6, September 2026.Abstract Space weather poses an important but under‐quantified threat to society. While severe geomagnetic storms are recognized as potential global catastrophes, their socio‐economic impacts remain poorly quantified. We present a novel physics‐engineering‐economic framework that links geophysical drivers to power grid geoelectric fields, transformer ...

Earth and Space Science, Volume 13, Issue 9, September 2026.Abstract This study develops a novel framework within the Weather Research and Forecast Model for modeling aerosol‐cloud‐lightning interactions. The framework explicitly represent aerosol‐cloud interactions by prescribing aerosols with two configurations: an idealized setup, where both cloud condensation nuclei (CCN) and ice nucleating particles (IN ...

Space Weather Mitigation Decisions by Critical Infrastructure Operators During Solar Cycle 25
Space Weather, Volume 24, Issue 9, September 2026.Abstract The “Gannon Storm” in May 2024 was the largest space weather event experienced in 20 years, generating auroras at latitudes as low as 35°, visible in Florida and Mexico. Such events pose significant operational challenges for critical infrastructure operators, particularly those managing electricity transmission networks, satellite ...
