“…In this work, the emphasis is on studying the relationship between the SCR proton flux and the parameters of type II radio bursts and on comparing the results with what is obtained from the parameters of microwave bursts. Earlier, in (Tsap and Isaeva, 2011Isaeva, , 2013, some issues were considered regarding the relationship between the SCR proton flux and the parameters of type II radio bursts. In the course of studies of the relationship between the frequency drift velocity of meter-decameter type II bursts and the intensity of the proton flux Ip of different energies, two families of events were discovered, which, according to Tsap (Isaeva and Tsap, 2011), suggests the generation of shock waves both in the region of the flare energy release and a moving coronal mass ejection (CME).…”

A comparative analysis showed that acceleration of protons by coronal shock waves is more effective than interplanetary shock waves, and that the main acceleration of protons occurs in the flare region and additional by the shock waves.…”

112 solar proton events (SPEs) were processed for the period from November 24, 2000 to December 20, 2014, which were accompanied by type II radio bursts. For the analysis, used original records of solar radio emission from a solar radio spectrograph in the range of 25-180 MHz, as well as original records of the flux intensity proton of solar cosmic rays (SCR) protons Ip with energy Ep in the range > 0.8-850 MeV according to data from the GOES series of devices. In this case, superimposed proton events were always separated and identified with the corresponding solar proton flares, and the maximum proton flux intensity Ip of superimposed proton events was determined from the level of the previous proton event. Based on data from the solar radio spectrograph, regression models were obtained for 91 type II bursts that established the relationship between the frequency drift velocity Vi,j and the frequency of type II bursts fi,j, and for 73 type II bursts it was possible to obtain regression models which established the relationship between the intensity of type II bursts Ii,j and type II burst frequency fi,j in the range 25-180 MHz. Detailed studies have shown that the intensity of type II bursts Ii,j, as well as the frequency drift velocity Vi,j, strongly depends on the frequency of type II burst fi,j and monotonically changes with time ti along the harmonics of type II bursts. As a result, the relationship between the maximum values of the SCR proton flux intensity Ip and the calculated values of the frequency drift velocity Vi,j and intensity of type II bursts Ii,j was investigated. A comparative analysis showed that the relationship between the intensity of the SCR proton flux Ip and the intensity of type II bursts Ii,j is much stronger than with the frequency drift velocity Vi,j, where the correlation coefficient r is 0.82 and 0.71, respectively, for protons with energies Ep > 30 MeV. The relationship between the proton flux intensity Ip and the frequency drift velocity Vi,j and the intensity of type II bursts Ii,j was also studied as a function of the proton energy Ep and the frequency fi,j of type II radio bursts. It was shown that the strongest relationship between the intensity of the SCR proton flux Ip with the frequency drift velocity Vi and with the intensity of type II bursts Ii,j is observed with subrelativistic SCR protons with energies Ep in the range > 30-100 MeV and for type II radio bursts at a frequency fi,j in the range 40-160 MHz.
