Zusammenfassung |
We present the results of a survey of 807 FTEs observed by Interball-1 on
the mid- and high-latitude dayside and flank magnetopause. Dayside
magnetosheath events show a strong tendency to occur for southward
magnetosheath magnetic fields suggesting origin via component (or perhaps
antiparallel) reconnection near the equatorial plane. Flank FTEs occur for
both magnetosheath magnetic field orientations with only a slight preference
for southward magnetosheath magnetic fields. These events are consistent
with generation along an extended subsolar component reconnection line for
all IMF orientations or a combination of reconnection along a subsolar
component reconnection line for southward IMF and antiparallel reconnection
at higher latitudes for northward IMF. The distribution of direct and
reverse magnetosheath FTEs and the tilt angle of the reconnection line for
dawnward and duskward IMF are in a good agreement with the theoretical
predictions of the component merging model. The clear anticorrelation
between the magnitude of the east/west (Bm) perturbation observed within
magnetosphere FTEs versus Bm in the magnetosheath also demands an
explanation of the FTEs in terms of reconnection along a tilted subsolar
merging line, e.g. in terms of component merging. |
