| Research Abstract |
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.
