Title: 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.
