Special issue}, month = {Mar}, note = {P(論文), The time lag and other characteristics between an SC and an onset of a substorm were investigated. A substorm onset was defined by an onset of a Pi2 magnetic pulsation observed at three mid-latitude observatories. A clear occurrence peak of the substorm onsets appeared statistically around 10 min after the onset time of the SC's, but it did not appear for the negative SI (SI^-) events. A typical example showed that this time lag was consistent with the idea of the substorm triggering in the near earth magnetotail. The necessity of the preconditions for the SC-triggering was not so clear, but the SC-amplitude dependence of the triggering probability was clear. These results strongly suggest the reality of the triggering of a substorm by a sudden compression of the deep magnetosphere.}, pages = {139--148}, title = {Characteristics of the association between an SC and a substorm onset}, volume = {26}, year = {1983} }
