The equatorial ring-current energy during magnetic storms as related to Dst activity indices
On the basis of geomagnetic activity indices Dst and solar wind parameters (velocity and density), we calculate the kinetic energy of the equatorial ring-current during the development of a magnetic storm, following the hypothesis of Sckopke's theorem. Supposing that the relaxation mechanisms o...
