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
