N.A. Barkhatov et al. Conclusion This paper the ability of determining the type who approached magnetosphere disturbed Solar Wind stream by analyzing the components of the wavelet spectra of the near-Earth space environment parameters and the geomagnetic field along the meridional chain stations is tests. The dynamics of the components of the spectrum of disturbances of the Solar Wind correspond to the Solar flux in the low-frequency (2-8 mHz) spectrum of magnetic disturbances at high-latitude stations is shown and can be used as a diagnostic tool of the plasma flow. The possibility of refinement of the plasma of the Solar Wind on the results of comparison of the spectral characteristics of disturbances PSW, IMF and the geomagnetic field is demonstrate. It is shown that the energy spectrum of the oscillations of these parameters reflects the internal structure of the corresponding plasma formation. Resulting conclusion of the fact that during geomagnetic storms caused by Solar plasma flows, some of the geomagnetic low disturbance on the surface associated with MHD disturbances in these flows and penetrates into the magnetosphere from the solar wind is indicative.
