| Zusammenfassung |
| This paper presents a global model of the Jovian magnetosphere which is valid
not only in the equatorial plane and near the planet, as most of the existing
models are, but also at high latitudes and in the outer regions of the
magnetosphere. The model includes the Jovian dipole, magnetodisc, and
tail current system. The tail currents are combined with the magnetopause closure
currents. All inner magnetospheric magnetic field sources
are screened by the magnetopause currents. It guarantees a zero normal magnetic
field component for the inner magnetospheric field at the whole magnetopause
surface. By changing magnetospheric scale
(subsolar distance), the model gives a possibility to study the solar wind
influence on the magnetospheric structure and auroral activity.
A dependence of the magnetospheric size on the solar wind dynamic pressure
psw (proportional to psw-0.23) is obtained. It is a stronger
dependence than in the case of the Earth's magnetosphere
(psw-1/6). The model of Jupiter's magnetospheric which is presented is a
unique one, as it allows one to study the solar wind and
interplanetary magnetic field (IMF) effects. |
