| Zusammenfassung |
We analyzed observations of the solar activities and the solar wind parameters associated with
large geomagnetic storms near the maximum of solar cycle 23. This analysis showed that strong
southward interplanetary magnetic fields (IMFs), formed through interaction between an
interplanetary disturbance, and background solar wind or between interplanetary disturbances
are an important factor in the occurrence of intense geomagnetic storms. Based on our analysis,
we seek to improve our understanding of the physical processes in which large negative Bz's are
created which will lead to improving predictions of space weather.
Key words. Interplanetary physics (Flare and stream dynamics;
Interplanetary magnetic fields; Interplanetary
shocks) |
