ARTICLE ANNOTATION

quote
The prerequisites for the possible influence of solar activity variations on the dynamics of sulfur dioxide (SO2) concentration in the atmosphere, which has a maximum in the solar radiation absorption spectrum in the ultraviolet range (190-220 nm), coinciding with the maximum in the ozone absorption spectrum, were the subject of the study of the hypothetical relationship between concentration of SO2 in atmosphere and Wolf numbers (W) in this paper. Indeed, the results of the study showed the presence of a statistical relationship between W and concentration of SO2 in atmosphere, obtained on the basis of correlation, wavelet and spectral analyses. The performed causal analysis showed that W and SO2 concentration are related not only statistically, but also by a causal dependence (causality function g(∆t)<1) in the range of time shifts ∆t=−10:+15 years), i.e. the dynamics of SO2 concentration are physically determined by solar activity variations, which confirms the hypothesis put forward. Since the main emitters of sulfur dioxide to the atmosphere is volcanic activity and anthropogenic component, the physical mechanism of influence of solar activity variations on SO2 content in the atmosphere remains unclear. One of the working hypotheses of causal dependence of SO2 concentration dynamics on solar activity variations may be based on interaction in the gas phase of ozone with hydrogen sulfide with formation of sulfur dioxide: H2S + O3 = SO2 + H2O.
