Are Storm-Time Substorms Triggered or Spontaneous? [PDF]

Journal of Astronomy and Space Sciences, 2004
Magnetic storms are almost always accompanied with substorms or substorm-like disturbances. Understanding the nature of the storm-time substorm is important for the currently critical issue of the storm-substorm relation.

Transpolar voltage and polar cap flux during the substorm cycle and steady convection events [PDF]

, 2009
Transpolar voltages observed during traversals of the polar cap by the Defense Meteorological Satellite Program (DMSP) F-13 spacecraft during 2001 are analyzed using the expanding-contracting polar cap model of ionospheric convection.

Quantifying the relative contributions of substorm injections and chorus waves to the rapid outward extension of electron radiation belt [PDF]

, 2014
We study the rapid outward extension of the electron radiation belt on a timescale of several hours during three events observed by Radiation Belt Storm Probes and Time History of Events and Macroscale Interactions during Substorms satellites and ...

Characterization of local time dependence of equatorial spread F responses to substorms in the American sector

Journal of Space Weather and Space Climate, 2023
Substorms have been found to play an important role in ionospheric electrodynamics at low and equatorial latitudes. In this study, we have investigated the possible influence of substorm on the generation of equatorial spread F (ESF).

Timing and location of substorm onsets from THEMIS satellite and ground based observations [PDF]

Annales Geophysicae, 2009
The unprecedented coverage of the THEMIS GBO station network coupled with high temporal and spatial resolution allowed us to determine the various stages of the global scale developments of the optical aurora at substorm onsets.

Coronal mass ejections, magnetic clouds, and relativistic magnetospheric electron events: ISTP [PDF]

, 1998
The role of high-speed solar wind streams in driving relativistic electron acceleration within the Earth\u27s magnetosphere during solar activity minimum conditions has been well documented.

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

Disappearance of plasmaspheric hiss following interplanetary shock [PDF]

, 2015
Plasmaspheric hiss is one of the important plasma waves controlling radiation belt dynamics. Its spatiotemporal distribution and generation mechanism are presently the object of active research.
