A Sequential Study on Three Long-Period Pi2 Events Associated with Mini-Substorms

P(論文) The smallest of the observed substorms, called mini-substorms, are found to accompany long-period (ranging from 150 to 300s) Pi2 pulsations. Worldwide and sequential features of Pi2 waves can be studied in detail by examining Pi2 events associated with mini-substorms. Three such events that oc...
