Research overview:
This study investigated the large-scale structural change of the earth's magnetotail during substorm (magnetosphere storm) using an analysis approach called superposed epoch analysis. The analysis was carried out for (1) a distant region of the magnetotail, and (2) a relatively near region. For the former, the generation and progress of plasmoid were clarified in detail. For the latter, the macroscopic structure of the magnetic recombination process was found. Through this study, it was definitely explained that, magnetic recombination plays an important role on the substorm phenomenon.
