摘要: The plasmasphere/ring-current/radiation-belt are interacting systems. magnetic field generated by the ring current changes drift paths of energetic particles. Pressure gradients in produce region 2 aligned currents, which close ionosphere and create an electric that acts to shield lower-latitude from full force convection. In turn, this shielding alters transport plasmaspheric plasmas. Furthermore, anisotropy plasmas excites waves cause pitch-angle energy diffusion radiation belt On other hand, precipitation electrons modifies ionospheric conductances, thus configuration magnetosphere-ionosphere system. A number models plasmasphere, have been developed study behaviors inner magnetosphere during geospace storms. However, majority these designed a particular plasma population, without consideration interactions others. paper, we briefly describe state-of-the-art current, belt, present results preliminary coupling effort. coupled shown certain observed features magnetosphere: post-midnight peak storm main phase ion flux; disturbance produced impulsive substorm injections, slow ramp-up geosynchronous fluxes associated with diffusion. We conclude presenting framework on together interactively make significant progress toward realistic interaction model.
