Abstract
In this paper we reveal the possibilities of Flicker-Noise Spectroscopy, a theoretical approach to the analysis of chaotic signals generated by complex astrophysical systems. To study the physicochemical processes occurring in the solar atmosphere, the daily sequences of the Zurich series and the brightness of the Fe XIV 530.3 nm green coronal line are parametrized. The correlation features of the time series of Wolf numbers associated with the selected resonant and high-frequency components of the analyzed signal are established. The calculation of the nonstationarity factor, which is a predictor of the most significant rearrangements in the atmospheric layers of the Sun, has been carried out. The analysis of frequency-phase synchronization in simultaneously fixed characteristics of solar activity is carried out.
