Relation of plasma sheet flows to different modes of magnetospheric response

Recent studies have demonstrated that every known type of auroral zone magnetic activity can be associated with flux closure in the magnetotail. These include pseudo breakups, substorms, poleward boundary intensifications, steady magnetospheric convection, and sawtooth injection events. As flux closure is caused by magnetic reconnection we expect that each of these can also be associated with fast flows in the tail. We have scanned magnetic index data during the 2008 and 2009 intervals when the Themis spacecraft passed through the tail (December-May) identifying examples of each type of event. We demonstrate that each mode of magnetospheric response can be associated with plasma flows. We examine the temporal relation of these flows to the onset times of each type of event as determined by a variety of onset signatures. We also describe the spatial distribution and properties of the flows. Since no sawtooth events have been identified in the Themis era we use Geotail plasma data in earlier more disturbed times to study this association.
