| Zusammenfassung |
| Interaction between interplanetary coronal mass ejections (ICMEs) and the background solar
wind plays an important role in determining the velocity and structure of ICMEs at 1 AU.
Interaction between ICMES can also significantly modify their structure, and recent studies
suggest that a significant proportion of large geomagnetic storms are associated with such
compound ICMEs. Here, we discuss case studies of two ICME events, the first showing clear
evidence of interaction between the ICME and the background wind, and the second
showing interaction between two ICMEs. We compare observations of the ICMEs
in interplanetary space from the EISCAT, MERLIN, and STELab interplanetary
scintillation (IPS) experiments, and from the STEREO heliospheric imagers, along
with the results of numerical modelling of the events, with the aim of obtaining a
better understanding of the physical processes controlling the evolution of ICMEs. |
