Variability of the climate and weather during the last decades demonstrated that the solar radiation (including EUV radiation) can not be unique source of energy for the near- Earth Space. Additional source of energy can be the particles constantly radiated by the Sun surface. Flux of the solar particles includes corona mass ejection (CME), connected with solar flares and local strong magnetic fields as well as a constant emanation of the solar particles connected with weak large-scale solar magnetic fields. Two kinds of the solar particles, which have different long term periodicity of variations, determine energy of solar wind which can penetrate inside the near- Earth Space. Experimental data demonstrated close connection between the atmospheric processes and the solar wind parameters. Processes of transmission energy of the solar wind inside near-Earth Space can be realized by means of the electric fields and currents which changes global electric system of Earth. Our experimental data in the Antarctica (Vostok Station) show a high correlation between values of electric field on ground surface and energy of the solar wind. One of the most important elements of the global electric circuit is a conductivity of the ground surface. So, transmission of energy of the solar wind inside the Earth's atmosphere will depend on this important parameter and will be different at different regions of the Earth, producing redistribution of temperature and pressure of the atmosphere. Experimental and model estimations of this mechanism are presented in this paper.
