Title: A self‐consistent model of the interacting ring current ions and electromagnetic ion cyclotron waves, initial results: Waves and precipitating fluxes
Abstract: Initial results from a newly developed model of the interacting ring current ions and ion cyclotron waves are presented. The model is based on the system of two kinetic equations: one equation describes the ring current ion dynamics, and another equation describes wave evolution. The system gives a self‐consistent description of the ring current ions and ion cyclotron waves in a quasilinear approach. These equations for the ion phase space distribution function and for the wave power spectral density were solved on a global magnetospheric scale under nonsteady state conditions during the 2–5 May 1998 storm. The structure and dynamics of the ring current proton precipitating flux regions and the ion cyclotron wave‐active zones during extreme geomagnetic disturbances on 4 May 1998 are presented and discussed in detail.
