Аннотация: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 p−0.23
sw ) is obtained. It is a stronger dependence than
in the case of the Earth’s magnetosphere (p−1/6
sw ). 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.
