  7. Auroral substorms & geomagnetic storms • Hypothesis (McFadden) • Substorms deposit EM • energy at low altitude. • Ionosphere expands, • promoting intense ion • outflows. • Stormtime electric fields • force outflowing ions into • near-earth plasmasheet. • Betatron acceleration • energizes earthward • convecting ions. • The now prodigious, • energetic ions further • energize the ring current, • intensifying the storm.
