Abstract

On the basis of observed data for the period from 2001 to 2012 obtained with GOES, SOHO (LASCO) satellites as well as the Radio Solar Telescope Network the relationship between the proton flux intensity Ip with energies Ep > 30 MeV, velocity of coronal mass ejections (CME) V cme, and fine spectral structure of meter–decameter type II radio bursts for 60 solar energetic events has been considered. The degree of plasma inhomogeneity in the vicinity of the shock front was characterized by the relative distance between neighbor strips at dynamic spectra of radio bursts. It has been established that the correlation coefficient between Ip and the multiplication of bV cme is 0.79. This shows evidence in favor of an important role of MHD turbulence in the course of proton acceleration.
