| Zusammenfassung |
| We present a local mesoscale model of the magnetospheric cusp region
with high resolution (up to 300 km). We discuss the construction
and implementation of the initial configuration and give a detailed
description of the numerical simulation. An overview of simulation
results for the case of strongly northward interplanetary magnetic
field (IMF) is then presented and compared with data from Cluster
2 spacecraft from 14 February 2003. Results show a cusp diamagnetic
cavity (CDC) with depth normal to the magnetospheric boundary on the order
of 1–2 RE and a much larger extent of ~5–9 RE tangential
to the boundary, bounded by a gradual inner boundary with the magnetospheric
lobe and a more distinct exterior boundary with the magnetosheath. These results
are qualitatively consistent with observational data. |
