We analyze Earth-Sun System disturbances taking into account that the magnetosphere of the Earth is formed in the process of turbulent solar wind flow around the magnetic field of the Earth and the geomagnetic tail is formed as the turbulent wake under the obstacle. We obtain the characteristics of the medium scale magnetospheric turbulence and distribution of plasma pressure using THEMIS, CLUSTER and INTERBALL data. It is shown, that the level of the turbulence is considerably decreased in comparison with plasma sheet turbulence at geocentric distances smaller than 10Re. The analysis of plasma distribution around the Earth reveals the existence of the surrounding the Earth at geocentric distances from ~7Re till ~10Re plasma ring with near azimuthally symmetric distribution of plasma pressure. Plasma pressure in the ring is near to isotropic, pressure gradients are mainly directed to the Earth. Topologically transverse currents in the ring constitute the high latitude continuation of the ordinary ring current. Nighttime currents in the ring are concentrated near the equatorial plane; daytime currents due to the daytime compression of the magnetosphere are spread along field lines. The role of turbulent transport in the magnetosphere of the Earth, localization of isolated substorm onset and scale free characteristics of system disturbances are discussed.
