| Zusammenfassung |
| We performed global MHD simulations of the geosynchronous magnetic
field in response to fast solar wind dynamic pressure (Pd)
enhancements. Taking three Pd enhancement events in 2000 as
examples, we found that the main features of the total field B
and the dominant component Bz can be efficiently predicted by the
MHD model. The predicted B and Bz varies with local time, with
the highest level near noon and a slightly lower level around
mid-night. However, it is more challenging to accurately predict the
responses of the smaller component at the geosynchronous orbit
(i.e., Bx and By). In contrast, the limitations of T01 model
in predicting responses to fast Pd enhancements are presented. |
