Scientific paper

The paper describes flux tube interchange motion in a corotating magnetosphere, adopting a Hamiltonian formulation that yields a very general criterion for instability. Expressions are derived for field-aligned currents that reveal the effect of ionospheric conductivity on interchange motion and instability growth rates are calculated. The absence of net current into the ionosphere demonstrates the bipolar nature of interchange flow patterns. It is pointed out that the convection shielding phenomenon in the terrestrial magnetosphere is a direct consequence of the interchange stability of the system. The paper is concluded with an extended analysis of the nature of interchange motion in the Jovian system.
