Geomagnetic activity effects on plasma sheet energy conversion
In this article we use three years (2001, 2002, and 2004) of Cluster plasma sheet data to investigate what happens to localized energy conversion regions (ECRs) in the plasma sheet during times of high magnetospheric activity. By examining variations in the power density, E ·J , where E is the electric field and J is the current density obtained by Cluster, we have studied the influence on Conc...
متن کاملCurrent sheet flapping motion and structure observed by Cluster
[1] Fast vertical flapping oscillations of the plasma sheet have been observed by Cluster on September 26, 2001. The flapping motion had vertical speeds exceeding 100 km/s, an amplitude in excess of 1 RE and a quasiperiod of 3 min. The current sheet was mostly tilted in the Y-Z plane (with the tilt sometimes exceeding 45 ). The waves had the properties of a kink mode and propagated toward the d...
متن کاملLocalized fast flow disturbance observed in the plasma sheet
An isolated plasma sheet flow burst took place at 22:02 UT, 1 September 2002, when the Cluster footpoint was located within the area covered by the Magnetometers-Ionospheric Radars-All-sky Cameras Large Experiment (MIRACLE). The event was associated with a clear but weak ionospheric disturbance and took place during a steady southward IMF interval, about 1 h preceding a major substorm onset. Mu...
متن کاملEntry of Plasma Sheet Particles into the Inner Magnetosphere Observed by POLAR/CAMMICE
Statistical results are presented from Polax/CAMMICE measurements of events during which the plasma sheet ions have penetrated deeply into the inner magnetosphere. Owing to their characteristic structure in energy-time spectrograms, these events are called "intense nose events." Almost 400 observations of such structures were made during 1997. Intense nose events axe shown to be more frequent i...
