| Zusammenfassung |
| Pi2 waves are an intergral part of the substorm process and have been
observed on the ground and in space. Using the special ability of Cluster to
determine the propagation direction of signals measured in the magnetometer
data, it is found that in the lobes of the Earth's magnetotail, for the cases
in this study, the Pi2 waves are travelling tailward. The polarization of the
waves in the lobes corresponds well with the polarization observed in the
highest latitude ground station. The propagation velocity of the Pi2 waves in
the lobes is basically Alfvénic. |
