Flux closure during a substorm observed by cluster, double star, IMAGE FUV, SuperDARN, and greenland magnetometers [PDF]

, 2006
We examine magnetic flux closure during an ex- tended substorm interval on 29 August 2004 involving a two-stage onset and subsequent re-intensifications.

The Shock‐Substorm of 24 September 1998: A Different Type of Substorm Trigger Onset

Geophysical Research Letters
An interplanetary shock triggered a substorm with a peak intensity SML = −1,781 nT on 24 September 1998. This is called a shock‐substorm here to differentiate it from generic substorms.

IMF By‐Controlled Dawn–Dusk and Hemispheric Asymmetries of Kelvin–Helmholtz Waves and Reconnection Geometry Under Negative Dipole Tilt

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Along with magnetic reconnection, Kelvin‐Helmholtz (KH) waves are the main mechanisms controlling the solar wind‐magnetosphere interaction, enabling plasma transport into the magnetosphere due to secondary reconnection, diffusion and wave‐particle interactions.

Substorms: Future of magnetospheric substorm—Storm research

Eos, Transactions American Geophysical Union, 1989
We have made good progress in revealing and understanding the great complexity of magnetospheric substorm phenomena and processes during the last two decades. In spite of such advance, however, there are several areas in which a serious attempt for new advance is required. Seven areas are identified for discussion. I would like to encourage the younger

Correlated Interball/ground-based observations of isolated substorm: The pseudobreakup phase [PDF]

, 2001
International audienceWe study the isolated substorm that occurred after a long quiet period, which showed all of the substorm signatures except for the first half hour of the expansion phase, which could be characterized as a pseudobreakup sequence ...

Substorm Effects on Chorus Emissions Modulated by ULF Waves

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Although cross‐scale wave‐particle interactions play a critical role in energy transfer in the magnetosphere, the influence of geomagnetic activity on the physical mechanisms involved remains unclear. In this study, we investigate this question by analyzing Van Allen Probes‐A observations of an event occurring on 25 July 2016.

Mercury's magnetospheric substorm and storm

地球与行星物理论评, 2022
Magnetospheric substorms and magnetic storms are explosive energy storage and release processes occurring during the interactions between the solar wind and planetary magnetospheres. They are accompanied by complex plasma dynamics processes and they have

Quantitative Evaluation of Energy Coupling between Quasi-Periodic Substorms and High-Speed Coronal Streams [PDF]

Journal of Astronomy and Space Sciences, 2008
It has been known that high-speed solar wind streams associated with coronal holes lead to quasi-periodic substorms that occur approximately every 2˜4 hours.

From physics of polar aurora to changes of the fundamental approaches to the physics of the magnetospheric processes

Frontiers in Astronomy and Space Sciences, 2022
One of the main problems of modern magnetospheric physics is the lack of a self-consistent explanation of the main physical processes based on the laws of plasma physics.

Numerical Investigations of Low‐Latitude Ground Magnetic Fields Due To Cavity Mode Oscillations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Pi2 oscillations are known to be associated with cavity mode oscillations (CMOs) in the inner magnetosphere at low latitudes. CMOs can also be excited by interplanetary shocks on the dayside. We present results from a global linear MHD wave model in spherical coordinates that allows us to analyze these waves at equatorial latitudes.
