Importance of initial ionospheric conductivity on substorm onset
Abstract
A substorm after a prolonged quiet period may differ from the typical one, as reported recently by Pellinen et al. (1982). The present knowledge on imperfect coupling between the magnetosphere and the ionosphere can explain qualitatively such a difference in terms of the role played by the initial conductivity of the ionosphere on substorm onset.
