Global Electric Circuit: Solar Wind, Magnetosphere, Ionosphere, Atmosphere

The aim of this paper is to investigate the global electric circuit and processes of solar wind-magnetosphereionosphere-atmosphere interaction.Also, I discuss the question as to how the magnetospheric energy source feeds the ionospheric current system.It is shown that a consistent application and further development of our structurally adequate magnetospheric model makes it possible to solve the magnetosphere-ionosphere coupling problem in regard to the formation of auroral electrojets by bulk currents generated in the geomagnetosphere.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.It is concluded that the whole of the complicated magnetospheric 'structure' only acts to redistribute, in space and time, currents and energy fluxes, which must be supplied by external sources to feed the dissipative processes in the ionosphere and in the atmosphere.
