First Kinetic 3‐D Simulations of the High‐Latitude Electrojet Spanning an Entire Turbulent Flux Tube

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Radar and rocket observations of the terrestrial ionosphere frequently measure turbulent plasma waves, especially during geospace storms. The non‐linear behavior of these waves remains poorly characterized. This paper presents the first fully kinetic 3‐D particle‐in‐cell simulations of Farley–Buneman (FB) turbulence spanning an entire high ...

Transient ULF pulsations: time dependence of magnetic fields observed at the ground

Annales Geophysicae
The continuum oscillation of a latitudinal range of closed geomagnetic field lines or shells appears to be a basic feature of the magnetosphere. Such oscillations are observed at the ground, and have been termed transient ULF pulsations.

Local Evolution of a Prenoon Drainage Plume

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Plasmaspheric drainage plumes are typically observed in the postnoon sector during geomagnetic storms, but their local evolution in the prenoon sector remains poorly understood. Here, we report in situ observations from the Van Allen Probe, revealing multiple localized enhancements in cold electron density near apogee in the prenoon sector ...

Interplanetary Electric Fields for Extreme Magnetic Storms

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Using a list of sudden‐commencement storms, the ring‐current index, and 1‐h near‐Earth solar‐wind measurements from solar cycles 20–25, we develop extreme‐value statistical models relating storm intensity D=max{−Dst} $D=\max \left\{-Dst\right\}$ to the storm main‐phase maximum duskward interplanetary electric field E $E$.

The Short and Long Timescale Responses of the Inner Magnetospheric EMIC Waves to the Solar Wind Dynamic Pressure

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The causal relationships between solar wind dynamic pressure and Electromagnetic Ion‐Cyclotron (EMIC) H+ ${\mathrm{H}}^{+}$, He+ ${\mathrm{H}\mathrm{e}}^{+}$, O+ ${\mathrm{O}}^{+}$ waves at L=3−6 $L=3-6$ are investigated with transfer entropy at short (<15 ${< } 15$ min) and long (>45 ${ >} 45$ min) timescales. The short timescale responses of
