Geomagnetic Disturbances Due To Neutral‐Wind‐Driven Ionospheric Currents

Space Weather
Previous simulation efforts on geomagnetic disturbances (GMDs) and geomagnetically induced currents (GICs) mostly rely on global magnetohydrodynamics models, which explicitly calculate the magnetospheric currents and carry certain assumptions about the ...

The Drag of Ionosphere Plasma Drifts on Thermospheric Zonal Winds During the 10–12 May 2024 Superstorm

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The observations from GRACE‐FO and DMSP satellites are utilized to analyze the ion‐neutral interaction near dusk during the 10–12 May 2024 super‐storm. The horizontal plasma convection dragged the anti‐sunward wind in the polar cap and sunward winds around the auroral and subauroral regions during whole storm times.

First Observation of the Second Harmonic of Upper Band Chorus Waves Linking to Slow Z‐Mode

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Z‐mode, comprising fast and slow branches, is a ubiquitous electromagnetic wave in planetary magnetospheres. While fast Z‐mode generation is attributed to electron cyclotron maser instability, the slow Z‐mode mechanism remains unresolved.

Revealing the Formation of the <20 MeV Inner Proton Radiation Belt at L ∼ 2 During the 10–11 May 2024 Superstorm

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract A new proton radiation belt was identified during the geomagnetic superstorm of 10–11 May 2024. To investigate its origin, we use an MHD‐test particle simulation to model solar energetic proton (SEP) trapping and the evolution of the initial trapped proton population during the storm.

How the Relative Contribution of DP‐1 and DP‐2 Currents Reshapes the Global Current System During Substorms

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Geomagnetic disturbances in polar regions can be decomposed into two main patterns: the Disturbance Polar (DP) 1 and 2. How their relative contribution reshapes global current system remains unclear. In this study, we classified substorms from 2010 to 2022 into weak and strong DP‐2 events based on the ratio of the eastward to westward auroral ...
