Description
Summary:The effect of global resonance in Jupiter’s middle magnetosphere is largely determined by the magnitude and functional dependence of the radial diffusion coefficient of relativistic electrons across magnetic shells. The relationship between the collective processes of formation of the radial distribution of density in an equatorial plasma disk in the case of interchange instability and the coefficient of radial diffusion of relativistic electrons is considered. A possible effect on the radial diffusion coefficient of pulsating fluxes of relativistic electrons that modify the ring current, which is a source of peculiar electromagnetic pulses in the middle magnetosphere, is noted. The magnitudes of the random transfers of energetic electrons across magnetic shells associated with the indicated factors, which contribute to the radial diffusion coefficient, are determined.
