Geomagnetic Activity and Lower Atmosphere Processes

Abstract

During substorms and storms, the ionosphere was subjected to rather a significant Joule heating, and the power of precipitating energetic particles was also great. If there is a mechanism for the 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 flux that arrives into the ionosphere during storms. In this study, I have briefly reviewed our present understanding of how these events play a key role in energy transfer from the solar wind into the magnetosphere and ionosphere, which ultimately results in the Earth's ionosphere-atmosphere coupling.
