Zusammenfassung |
We describe the methodology used to set up and compute spatial derivatives
of the electron moments using data acquired by the Plasma
Electron And Current Experiment
(PEACE) from the four Cluster spacecraft. The results are used to
investigate electron vorticity in the foreshock. We find that much
of the measured vorticity, under nominal conditions, appears to be
caused by changes in the flow direction of the return (either reflected
or leakage from the magnetosheath) and strahl electron populations
as they couple to changes in the magnetic field orientation. This
in turn results in deflections in the total bulk velocity producing
the measured vorticity. |
