MFF-Parameterization of Statistical Memory Effects in the Dynamics of Solar Magnetic Activity Indicators

In this paper, within the framework of the Memory Functions Formalism, we study the dynamic features of the sequence of daily Wolf numbers. The effects of aftereffects and statistical memory, as well as dynamic intermittency, realized against the background of periodicity and cyclicity of solar activity, have been studied. Specific spatiotemporal structures of phase portraits of orthogonal dynamic variables, identified for maxima and minima of solar activity, were discovered, as well as predictors consisting of changes in the effects of statistical memory in periods preceding extremes. The results obtained complement the existing information on the dynamics of physical and chemical processes occurring in the solar atmosphere and convective zone.
