A frontier study for elucidating the triggering and driving mechanisms of substorms

亚暴是在磁层和电离层释放大量能量的现象。我们研究了这些亚暴，旨在通过分析同时由航天器和地面观测获得的数据来阐明它们是如何触发和衍生的。我们证实了之前提出的亚暴模型的有效性。此外，我们可以获得与亚暴相关的极光公里辐射的几个重要特征。

Substorm are known as phenomena releasing large amount of energies in both magnetosphere and ionosphere. We investigated such substorms aiming at elucidating how they are triggered and derived by analyzing data obtained by simultaneous spacecraft and ground-based observations. We confirmed the validity of the model of substorm we proposed previously. Further, we could obtain several significant features of substorm-associated auroral kilometric radiations.
