geomagnetism

IntroductionGeomagnetically induced currents (GICs) pose a critical space weather hazard to ground-based conductive infrastructure. Previous studies have commonly identified large GIC events using daily maximum amplitudes exceeding 10 A, a criterion that may obscure the detailed temporal structure of GIC disturbances.MethodsIn this study, we apply an improved identification criterion to systemati…

Geomagnetic storms don’t directly harm humans on the ground thanks to Earth’s protective atmosphere, but research shows they can subtly influence cardiovascular health, sleep cycles, mood, and technology-dependent lifestyles. Their indirect effects—like GPS disruption or radiation exposure for airline crews—make them important to understand. Discover the effects of geomagnetic storms on humans—im…
