Аннотация:Magnetosphere of the Earth is well known reservoure of the energetic particles. Radiation belt models succsesfully describes spatial, pitch-angle and energy particle distribution in undisturbed conditions. During the magnetospheric disturbances, especially during strong magnetic storms there are still many unsolved problems, concerning energetic auroral particles acceleration during substorms, relativistic electron acceleration and losses, solar proton trapping and acceleration in the inner magnetosphere. Recently energetic particle acceleration in the atmosphere was registered as well. We illustrate some events when the strong redistribution of energetic particles in the magnetosphere is observed. Selected results of such type, especially the experimental ones, as well as the problems remaining to be solved, are discussed in our short review.
