- Аннотация: Outer radiation belt (ORB) relativistic electron fluxes dropouts during storm main phases, around 45%–50% after storms enhancements, 20%–25% after storms depletion, and 25%–28% almost unchanged continue to be unsolved problems in spite of many researches including the realization of RBSP/Van Allen mission. Ordinarily discussed mechanisms of partle precipitation and magnetopause shadowing can not explain the existence of magnetic storms when particle fluxes after storm restore till the level of the fluxes before the storm. Popular “quasilinear” models cannot explain time intervals of great increases of ORB fluxes near to substorm time intervals. Such situation is explained by the underestimation of the role of auroral processes in the ORB dynamics. We summarize the latest findings in the ORB and auroral processes connections including outer part of ORB intersection with the region of the auroral oval mapping to the equatorial plane, auroral oval motion to lover latitudes during magnetic storms, great magnetic field variations at the equatorial plane during storms and a number of other effects. The dominant role of adiabatic mechanism in the ORB dynamics during storm main and recovery phases is demonstrated. The ORB dynamics prediction and plans of future works including analysis of data of auroral missions are discussed.
