Equivalent electric circuit of magnetosphere-ionosphere-atmosphere interaction

Abstract

The aim of this study is to investigate the magnetospheric disturbances effects on complicated nonlinear system of atmospheric processes. During substorms and storms, the ionosphere was subjected to rather a significant Joule heating, and the power of precipitating energetic particles was also great. Nevertheless, there were no abnormal variations of meteoparameters in the lower atmosphere. If there is a mechanism for the powerful magnetospheric disturbance effect on meteorological processes in the atmosphere, it supposes a more complicated series of many intermediates, and is not associated directly with the energy that arrives into the ionosphere during storms. I discuss the problem of the effect of the solar wind electric field sharp increase via the global electric circuit during magnetospheric disturbances on the cloud layer formation.
