Interplanetary magnetic field control of dayside transient event occurrence and motion in the ionosphere and magnetosphere
International audience The pressure pulse model for dayside transient ionospheric events predicts dawnward moving events at and prior to local noon during periods of spiral interplanetary magnetic field (IMF) orientation, but duskward moving events at and after local noon during rarer periods of ort...
