摘要: Evidence is presented indicating that the structure of polar magnetic substorms determined by intensification current at northern and/or southern borders a small pre-existing westward electrojet. The substorm onset characterized growth border electrojet and further develops through quasi-periodic intensifications part varies only sporadically in intensity, its strength general stability make it center activity throughout course substorm. occurs roughly 15-min intervals thought to be connected with westward-traveling surge observed during auroral suggests input energy from magnetotail.
