THE RELATIVISTIC SOLAR PROTONS AS THE SOURCE OF THE FORMATION OF AEROSOLS AND OZONE «MINI HOLES» AT HIGH LATITUDES

Examines the impact of solar relativistic protons injected from solar flares on the ozone layer and the content of aerosols at the high atmosphere of the Earth. Calculations showed that a homogeneous photochemical theory does not apply to assess the impact of corpuscular radiation on the ozone total content (OTC). A qualitatively different scheme of physical processes using ion nucleation mechanism is suggested. For a quantitative test of the experimental results were calculated changes in the distribution of high-rise concentration of condensation nuclei (aerosol formation centers) during some large solar proton events such as Ground Level Events (GLE), which are characterized by the presence of relativistic protons with energies E > 450 MeV. Comparison of the re-sults of experimental observations and model calculations helped us to interpret some of the differences ob-served in the variations of the OTC during GLE by various features of the spectral characteristics of the incident solar protons.
