Accounting of the process of magnetospheric loading by the kinetic energy of the solar wind in the problem of classification of isolated substorms

The study classifies isolated magnetospheric substorms according to the temporal characteristics of substorm phases together with data on the solar wind and interplanetary magnetic field parameters. The classification results demonstrate causal relations of substorm activity with the characteristics of the solar wind flux flowing to the Earth’s magnetosphere. Combinations of solar wind parameters are utilized to account for the process of solar wind kinetic energy loading into the polar magnetosphere. Neural network experiments have shown that the dynamic parameters of substorm activity contain information about the characteristics of plasma flows. This was expressed in the detection of classes of the studied patterns that correspond to the physical concepts of generation of high-latitude geomagnetic activity.
