Description

Recent experimental results show that the magnetosphere, ionosphere, and neutral atmosphere must be viewed as a strongly coupled electrodynamic system subjected to excitation by substorms. Electric fields are believed to be the primary cause of many substorm effects including E x B drifts, modulations of coupling fluxes between the ionosphere and magnetosphere, heating of the neutral atmosphere, etc. These effects depend strongly on local time and season as well as on substorm intensity. Theoretical studies of the coupled ionosphere-plasmasphere system show that many aspects of the substorm behavior observed by whistlers and ionosondes can be explained by substorm electric fields.
