Magnetospheric substorms

Eos, Transactions American Geophysical Union, 1968
The magnetospheric substorm is perhaps the most widely known yet most poorly understood facet of magnetospheric disturbances. It is generally agreed that the substorm results from an explosive conversion of magnetic energy generated by the interaction between the solar wind and the magnetosphere.

KHI Development Between Inner LLBL and Magnetosphere on the Far Flanks as Observed by the MMS Mission

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract A boundary layer of finite thickness separates the magnetosheath and the magnetosphere. Within this boundary, we have the outer low‐latitude boundary layer (LLBL), the magnetopause current layer, and the inner LLBL. Earlier works point out that the interface on which Kelvin‐Helmholtz Instability (KHI) develops has implications for how ...

Investigating the Occurrence of Kelvin‐Helmholtz Instabilities at Jupiter's Dawn Magnetopause

Geophysical Research Letters, 2023
We use the Kelvin‐Helmholtz instability (KHI) condition with particle and magnetic field observations from Jovian Auroral Distributions Experiment and MAG on Juno along the dawn flank of Jupiter's magnetosphere. We identify the occurrence of magnetopause

Laboratory Realization of Magnetopause‐Like Reconnection in Space Plasma Environment Research Facility (SPERF)

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Magnetic reconnection explosively converts magnetic energy into plasma heating and particle acceleration. At Earth's magnetopause, reconnection governs solar wind‐magnetosphere coupling and drives global convection. Understanding these processes requires resolving reconnection's spatiotemporal evolution, which is difficult for in situ ...

Observation of a Knotted Electron Diffusion Region in Earth's Magnetotail Reconnection

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Magnetic reconnection is a fundamental plasma process that alters the magnetic field topology and releases magnetic energy. Most numerical simulations and spacecraft observations assume a two‐dimensional diffusion region, with the electron diffusion region (EDR) embedded in the same plane as the ion diffusion region (IDR) and a uniform guide ...

Magnetosphere

Eos, Transactions American Geophysical Union, 1991
Research on the terrestrial magnetosphere, above 500 km, continues to focus on how energy gets from the solar wind into the magnetosphere and how it circulates through the magnetosphere. The prime candidate for energy coupling has long been magnetic merging in which the magnetic field that the solar wind carries from the Sun merges with the geomagnetic

Oxygen and hydrogen ion abundance in the near-Earth magnetosphere: Statistical results on the response to the geomagnetic and solar wind activity conditions

, 2012
The composition of ions plays a crucial role for the fundamental plasma properties in the terrestrial magnetosphere. We investigate the oxygen-to-hydrogen ratio in the near-Earth magnetosphere from -10 RE274 keV O+ ion intensities, relative to the ...

Linking Very Near‐Earth Reconnection (VNERX) to Mid‐Latitude GICs: Evidence From the 7 September 2017 Storm

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Geomagnetically Induced Currents (GICs) are a hazard to power systems. In this letter, we present a case study to understand why a Sudden‐Commencement‐associated 20A GIC spike, measured at mid‐latitude in Virginia, US, increased to 30A within 2 min of interplanetary shock arrival.

Electrospherics and magnetospherics [PDF]

Electrical Engineering, 1959
In the second part of a two-part article, additional experiments with small spheres of magnetic material are described. Not only are the results interesting in themselves, but also it is hoped that they may serve as analogs for such phenomena as Brownian movement, thermal movement of molecules, crystal formation, bacterial chaining, and others.

Large Scale Earth's Bow Shock with Northern IMF as simulated by PIC code in parallel with MHD model

, 2016
In this paper, we propose a 3D kinetic model (Particle-in-Cell PIC ) for the description of the large scale Earth's bow shock. The proposed version is stable and does not require huge or extensive computer resources.
