Present day challenges in understanding the geomagnetic hazard to national power grids [PDF]

, 2009
Power grids and pipeline networks at all latitudes are known to be at risk from the natural hazard of geomagnetically induced currents. At a recent workshop in South Africa, UK and South African scientists and engineers discussed the current ...

Regional and Seasonal Effects of Geomagnetic Storms on Terrestrial Weather

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract It has long been a mystery why small Total Solar Irradiation changes have significant effects on Earth's climate. Solar cycle correlation studies abound but cannot conclusively point to a viable physical mechanism. Here, I show that geomagnetic storms have a profound terrestrial weather impact.

First Detection of the Two‐Dimensional Vertical Propagation of Traveling Ionospheric Disturbances Associated With Atmospheric Gravity Waves in the Martian Ionosphere

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We report the detection of a traveling ionospheric disturbance (TID) captured by the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) Active Ionospheric Sounding (AIS) instrument aboard the Mars Express spacecraft at 150–250 km altitude.

Solar Transients disturbing the Terrestrial Magnetic Environment at Higher Latitudes

, 2013
Geomagnetic field variations during five major Solar Energetic Particle (SEP) events of solar cycle 23 have been investigated in the present study. The SEP events of 01 oct 2001, 04 Nov 2001, 21 Apr 2002 and 14 May 2005 have been selected to study the ...

LEO‐DOS Absorbed Dose Observations During the May 2024 Geomagnetic Superstorm

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Low‐Earth Orbit Space Radiation Dosimeter (LEO‐DOS) onboard Next‐Generation Satellite II (NEXTSat‐2) measured absorbed dose rate variations during the May 2024 geomagnetic superstorm. The observations show deep storm‐time penetration of solar energetic particle (SEP) spanning L ≈ 2–10, a pronounced enhancement near L ≈ 3 consistent with ...

Geoeffectiveness and efficiency of CIR, Sheath and ICME in generation of magnetic storms

, 2011
We investigate relative role of various types of solar wind streams in generation of magnetic storms. On the basis of the OMNI data of interplanetary measurements for the period of 1976-2000 we analyze 798 geomagnetic storms with Dst < -50 nT and their ...

Direct Ionosonde Evidence of F‐Layer Disturbances Driven by Intense Lightning Activity at Low Latitudes

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Thunderstorms could cause the irregularities of electron density distributions in the ionosphere by exciting gravity waves and modifying ambient electric field (E‐field). By comparing the DPS‐4D ionosonde observation at 5‐min resolution at Fuke Station in Hainan, China with the lightning detection data, we studied the F‐layer responses to a ...

Geomagnetically Induced Currents in the Irish Power Network during Geomagnetic Storms

, 2016
Geomagnetically induced currents (GICs) are a well-known terrestrial space weather hazard. They occur in power transmission networks and are known to have adverse effects in both high and mid-latitude countries.
