Potential merits for substorm research from imaging of charge-exchange neutral atoms [PDF]
Annales Geophysicae, 1995 The in situ observations of the Earth magnetosphere performed over the past decades of space research have provided a rather good understanding of many partial localized processes of the magnetospheric substorm.

Stormtime substorm onsets: occurrence and flow channel triggering [PDF]
Earth, Planets and Space, 2018 Bright auroral emissions during geomagnetic storms provide a good opportunity for testing the proposal that substorm onset is frequently triggered by plasma sheet flow bursts that are manifested in the ionosphere as auroral streamers.

Simultaneous observation of auroral substorm onset in Polar satellite global images and ground-based all-sky images [PDF]
Earth, Planets and Space, 2018 Substorm onset has originally been defined as a longitudinally extended sudden auroral brightening (Akasofu initial brightening: AIB) followed a few minutes later by an auroral poleward expansion in ground-based all-sky images (ASIs).

Probabilistic modelling of substorm occurrences with an echo state network [PDF]
Annales Geophysicae, 2023 The relationship between solar-wind conditions and substorm activity is modelled with an approach based on an echo state network. Substorms are a fundamental physical phenomenon in the magnetosphere–ionosphere system, but the deterministic prediction of ...

Electron precipitation characteristics during isolated, compound, and multi-night substorm events [PDF]
Annales Geophysicae, 2021 A set of 24 isolated, 46 compound, and 36 multi-night substorm events from the years 2008–2013 have been analysed in this study. Isolated substorm events are defined as single expansion–recovery phase pairs, compound substorms consist of multiple phase ...

Alternating bursts of low energy ions and electrons near the substorm onset [PDF]
Annales Geophysicae, 2006 The substorm associated behavior of the low energy particles (30 eV–28.5 keV) near the earthward edge of the plasma sheet is examined using data from CRRES during the late growth and early expansion phases of a substorm on 12 March ...

Multiple magnetic dipolarizations observed by THEMIS during a substorm [PDF]
Annales Geophysicae, 2011 The magnetic field dipolarization in the vicinity of substorm onset and during substorm expansion phase during the period of 06:00–06:40 UT on 15 February 2008 is investigated with observations from multiple probes of THEMIS.

The efficiency of mechanisms driving Subauroral Polarization Streams (SAPS) [PDF]
Annales Geophysicae, 2011 We have investigated the seasonal and diurnal variation of SAPS (Subauroral Polarization Streams) occurrence based on 3663 SAPS events identified in DMSP ion drift observations in the Northern Hemisphere during July 2001 and June 2003.
