Analysis of the long-term evolution of solar activity based on a series of Volf numbers (II. Results)

The article presents the investigation results of the evolution of Volf numbers statistical characteristics and a number of sunspot groups changeability in the period of 100 years. On the basis of statistical semi-empirical model of Volf numbers distribution the authors assume that modeling distribution parameters variability in the period of 100 years is possible to characterize in terms accumulation-dump of energy of the Sun. The authors discuss a possible mechanism of such solar activity evolution.
