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.
