Abstract

This paper presents results of observational and modeling work on the dynamics in the inner magnetosphere during geomagnetic storms. Using statistics from POLAR/CAMMICE/MICS instrument it is shown that the ring current energy density is a complex function of the solar wind input and substorm activity. These results are examined using time-varying models for the magnetic and electric fields during storm periods. It is shown that (even strong) stationary convection electric field does not produce a sufficiently high-energy ring current. The same is true for a single electric field pulse representing an isolated substorm. Our preliminary results indicate that a series of substorms with inward transport and acceleration of particles by inductive electric fields are required for the production of an intense ring current.
