Wavelet image of the fine structure of the 11-year cycle based on studying cosmic ray fluctuations during cycles 20-23

摘要

A non-stationary transient oscillating process of the solar magnetic field polarity reversal of approximate to 3 years in duration has been established: a U-shaped dynamics in the wavelet representation of variations in the scintillation index of galactic cosmic rays (GCRs) ( approximate to 7, 13 - 14, and approximate to 7 solar rotations). The transient oscillating process of the field reversal is concluded with a sharp and deep decrease in the GCR intensity at the branch of 11-year cycle decline ( 1972, 1982, 1991, and 2003). The duration of the transient process inversely depends on the 11-year cycle amplitude. Retardation of relaxation oscillations during "weak" cycles ( 20 and 23) explains "anomalous" solar activity in 1972 and 2003. A decrease in the amplitude of the current cycle 23 is accompanied by an increase in its duration, which can mean that the 11-year cyclicity has become anomalous. The constancy of the energy released in a single cycle indicates that the 11-year cycle is the mechanism of energy regulation preventing the Sun from "overheating" at the critical temperature.
