In the period following a geomagnetic storm the high-latitude, magnetospheric-driven convection pattern is normally weak. However, the neutral circulation, set up by ion-neutral momentum coupling during the main phase of the storm, may continue for several hours after the storm has ended. This persistent neutral circulation has the potential to drive Hall currents for some hours. In this paper we investi- gate these "flywheel" currents by simulating a storm which occurred on the 23 rd of…

The effects of neutral inertia on ionospheric currents in the high-latitude thermosphere following a geomagnetic storm
Results of an experimental and theoretical investigation into the effects of the time dependent neutral wind flywheel on high-latitude ionospheric electrodynamics are presented. The results extend

Ionospheric signature of the tail neutral line during the growth phase of a substorm
An isolated substorm occurred on October 21, 1981 at the end of a large geomagnetic storm. Observations of particles and fields were made during the presumed growth phase of this substorm by the DE 2
How Does the Thermosphere and Ionosphere React to a Geomagnetic Storm
Unraveling the ionospheric and thermospheric response to a geomagnetic storm has been a challenge for many decades, due largely to the complex interactions between the plasma and neutral species.

The Earth’s upper atmosphere at high latitudes is a complicated region that is under the influence of many competing forces. For one, it is where the atmosphere becomes partially ionised, and thus
