The 12th International Conference on Substorms

Edited by: Kazuo Shiokawa, Masaki Fujimoto, Olaf Amm, Mei-Ching H. Fok

This special issue presents papers from the ICS-12 (the 12th International Conference on Substorms) that broadly address various aspects of substorms, i.e., substorm processes in the tail, interaction between the tail and the inner magnetosphere and ionosphere, substorm currents and their dynamics, and the role of substorms in geospace energetics, as well as the role of MHD and kinetic instabilities in substorms. Other substorm-related research topics are also presented, such as the storm-substorm relationship, ULF/ELF/VLF waves, and non-Earth substorm-like features.

    Latitudinal dependence on the frequency of Pi2 pulsations near the plasmapause using THEMIS satellites and Asian-Oceanian SuperDARN radars

    We herein describe a harmonic Pi2 wave that started at 09:12 UT on August 19, 2010, with data that were obtained simultaneously at 19:00–20:00 MLT by three mid-latitude Asian-Oceanian Super Dual Auroral Radar ...

    The AUTUMNX magnetometer meridian chain in Québec, Canada

    The AUTUMNX magnetometer array consists of 10 THEMIS-class ground-based magnetometers deployed to form a meridian chain on the eastern coast of Hudson Bay in eastern Canada, a second partial chain one hour of ...

    The February 24, 2010 substorm: a refined view involving a pseudobreakup/expansive phase/poleward boundary intensification sequence

    A substorm on February 24, 2010 was chosen for study by Connors et al. (Geophys. Res. Lett. 41:4449–4455, 2014) due to simple symmetric subauroral magnetic perturbations observed in North America. It was shown...

    Eastward-expanding auroral surges observed in the post-midnight sector during a multiple-onset substorm

    We present three eastward-expanding auroral surge (EEAS) events that were observed intermittently at intervals of about 15 min in the post-midnight sector (01:55–02:40 MLT) by all-sky imagers and magnetometers...

    Problems with mapping the auroral oval and magnetospheric substorms

    Accurate mapping of the auroral oval into the equatorial plane is critical for the analysis of aurora and substorm dynamics. Comparison of ion pressure values measured at low altitudes by Defense Meteorologica...

    Inverting magnetic meridian data using nonlinear optimization

    A nonlinear optimization algorithm coupled with a model of auroral current systems allows derivation of physical parameters from data and is the basis of a new inversion technique. We refer to this technique a...

    Further evidence for the role of magnetotail current shape in substorm initiation

    Substorm initiation still remains an unsolved problem, even though there is a consensus among most researchers that its main stages include dayside reconnection and substorm expansion. Dayside reconnection res...

    Reconnection and interchange instability in the near magnetotail

    This paper provides insights into the possible coupling between reconnection and interchange/ballooning in the magnetotail related to substorms and flow bursts. The results presented are largely based on recen...

    Relativistic electron acceleration during HILDCAA events: are precursor CIR magnetic storms important?

    We present a comparative study of high-intensity long-duration continuous AE activity (HILDCAA) events, both isolated and those occurring in the “recovery phase” of geomagnetic storms induced by corotating int...
