On the Relationship Between DP-1, DP-2, the Growth and Expansion Phases of Substorms, and Ionospheric Electric Fields
Abstract
The problem of understanding the physical conditions preceding and causing the explosive or expansion phase of substorms has been studied for several years. In its most recent form this problem concerns questions of the existence of a growth phase prior to the explosive phase of a substorm and whether, if it exists, the growth phase current systems are fundamentally different from those during the expansion phase. The purpose of the present letter is to show that the resolution of different views on these questions may be achieved through examination of ionospheric electric field data obtained during isolated substorms.
