On the Causes of Geomagnetic Activity.

Abstract

The causes of geomagnetic activity are studied both theoretically in terms of the reconnection model and empirically using the am-index and interplanetary solar wind parameters. It is found that two separate mechanisms supply energy to the magnetosphere. One mechanism depends critically on the magnetude and direction of the interplanetary magnetic field. Both depend strongly on solar wind speed.
