, 2019 A geometric wedge model of the near-earth nightside plasma sheet is used to derive a wave equation for low frequency shear flow-interchange waves which transmit $\vec{E} \times \vec{B}$ sheared zonal flows along magnetic flux tubes towards the ionosphere.

Two‐Dimensional Equilibrium Model of Planetary Magnetotail in Generalized Nonthermal Plasmas
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Solar wind‐magnetosphere interaction may result in an elongated magnetotail with stored magnetic field energy. This study presents for the first time a family of asymptotic solutions for stretched two‐dimensional magnetotail equilibrium in generalized nonthermal plasmas, including the Kappa‐like and Maxwellian‐like velocity distributions with ...

Real-time ISEE data system [PDF]
, 1979 A real-time ISEE data system directed toward predicting geomagnetic substorms and storms is discussed. Such a system may allow up to 60+ minutes advance warning of magnetospheric substorms and up to 30 minute warnings of geomagnetic storms (and other ...

Intense Ground Magnetic Perturbations During the 2024 May and October Geomagnetic Storms
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract The May and October 2024 geomagnetic storms represent two of the most intense space weather events of Solar Cycle 25. While differing in global intensity, both storms produced extreme ionospheric disturbances, including equatorward auroral expansion to mid‐latitudes and rapid geomagnetic variations (dH/dt $\text{dH}/\text{dt}$).

Titan’s influence on Saturnian substorm occurrence
Geophysical Research Letters, 2008 Substorms play an important role in the energization and transport of plasmas in planetary magnetospheres, including the shedding of the mass added by moons in the case of Jupiter and Saturn.

Another way of deriving the ring current decay time during disturbed periods
Annals of Geophysics, 1995 Coupling parameter, E, and the total energy dissipated by the magnetosphere, UT, are determined for six disturbed periods, following three known criteria for UT computation.

Multiple-satellite studies of magnetospheric substorms: Plasma sheet recovery and the poleward leap of auroral-zone activity [PDF]
Particle observations from pairs of satellites (Ogo 5, Vela 4A and 5B, Imp 3) during the recovery of plasma sheet thickness late in substorms were examined.

Eos, Transactions American Geophysical Union, 1989 The substorm is a thing obscure/ We cannot make it out for sure/ But physicists with lots of nerve/ Fill in details they can't observe/ They see it in their own grand visions/ Of tearing modes with no collisions/ That squeeze away the plasma sheet/ To make opposing fluxes meet/ And in their merging, oh so swift/ Great plasmoids are cut adrift/ Or else ...

Timescales of Birkeland Currents Driven by the IMF
Geophysical Research Letters, 2019 We obtain current densities from the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE), alongside By and Bz from the Interplanetary Magnetic Field (IMF) for March 2010.

Auroral effects in the D region of the ionosphere [PDF]
The possible effects are discussed of radiations and corpuscles on relatively short-term changes in the circulation of the atmosphere (the development of cellular patterns in the zonal westerly flow, leading to the formation of cyclones) and relatively ...
