Impact of Solar Irradiance on Storm‐Time Thermospheric Mass Density Response
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract As a key parameter in the externally forced ionosphere–thermosphere (IT) system, mass density response to storms is affected by the prevailing solar irradiance. To better understand this relationship, we examine mass density responses to the same storm but with different background solar irradiance levels.

A Study of the Morphology of Magnetic Storms: Moderate Magnetic Storms [PDF]
, 1957 Some average characteristics are determined for 136 moderate magnetic storms with sudden commencements that occurred during the interval 1902-1945.

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract We analyze the response of mean winds and semidiurnal tides (SDTs) in the mesosphere and lower thermosphere (MLT; ∼70–110 km altitude) to the May 2024 geomagnetic super storm, based on meteor radar (MR) observations from King Sejong Station (KSS; geographic: 62.22°S, 58.78°W; geomagnetic: 53.27°S, 10.88°E) in the Antarctic Peninsula.

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Extreme conditions during storms profoundly alter the evolution of equatorial plasma bubbles (EPBs), yet the key dynamics remains poorly understood. We document the rapid expansion, contraction, and decay of super EPBs in South America during the 12 November 2025 storm with Interplanetary Magnetic Field (IMF) Bz/By magnitude exceeding ∼50 nT ...

Global Long‐Term Trends in Ionospheric TEC From GNSS Observations With Local‐Time Dependence
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Long‐term ionospheric changes are expected as a consequence of thermospheric cooling driven by increasing greenhouse gas concentrations. We analyze global ionospheric total electron content (TEC) derived from GNSS observations for 2000–2024 using the high‐resolution ISEE data set.

Fully Kinetic Simulations of Ion‐Acoustic Waves in Asymmetric Reconnection With Cold Ions
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract In collisionless plasma, ion‐acoustic wave (IAW) is an important candidate for enhancing resistivity and viscosity, yet their presence and role in magnetic reconnection remain poorly understood. Here, we employ 2.5‐D particle‐in‐cell simulations to investigate IAWs in asymmetric magnetopause reconnection involving a cold ion population ...

RESPONSE OF BIOLOGICAL SYSTEMS TO GEOMAGNETIC STORMS
Acta Biomedica Scientifica, 2018 At present, influence of weak magnetic fields associated with solar and geomagnetic activity on biological systems is gaining more interest. Taking into account the accumulated data on the influence of geomagnetic storms on different biological levels ...

Hiss Wave Evolution During Substorms Based on Van Allen Probes Observations
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract Hiss waves frequently occur in the plasmasphere or plumes, playing a key role in energetic electron loss in the Earth's inner magnetosphere. While previous studies have linked hiss wave enhancements in the outer plasmasphere (just inside the plasmapause) to electron injections during substorms, their evolution across various substorm phases ...
