- Аннотация: We summarize the latest finding on the validity of Tverskaya relation and the position of themaximum of the outer radiation belt (ORB) formed after a geomagnetic storm and the appearance of large fluxes of relativistic electrons after a storm. Specifically, the Tverskaya relation connects the minimal value of the Dst index observed during a storm and the position of the aforementioned maximum fluxes that correspond to the formation of a new ORB after storm, allowing us to predict the position of ORB maximums for the most of magnetic storms based solely on the Dst predictions. It was shown that large fluxes of ORB relativistic electrons are formed only if the comparatively large substorms are formed during the storm recovery phase, which permits to predict the appearance of large relativistic electron fluxes. Observed dependences were explained theoretically based on the analysis of the ring current formation and stability. This theory had a number of predictions, which have recently been verified, including the dominant role of the adiabatic mechanism of the ORB flux variations and the intersection of the position of the ORB with the position of the source of the auroral oval electrons at the equatorial plane, the local increases of the relativistic electron fluxes during substorms and a number of another effects.
