The Jovian magnetospheric magnetic and electric fields: Effects of the interplanetary magnetic field

The purpose of this paper is to study using a constructed magnetospheric magnetic field model the electric fields and plasma motions caused by Jupiterʹs rotation and the solar wind MHD generator. Analysis of observations shows that a complicated differential rotation system is operating in the jovian magnetosphere. Observational data also reveal the presence of solar wind plasma in the jovian magnetosphere. However, the processes by which it crosses the magnetopause are left unexplained. Here we present an approach to the fundamental problem of the nature of the global plasma convection and corotation in the jovian magnetosphere. The constructed model allows us to map the various parts of the magnetosphere into the ionosphere and vice versa in order to correlate them with the different regions and processes.
