Fig. 7

Long-term (preserving the periods ~13.00, ~6.50, and ~4.34 years) phase space radius, R, for: the sunspot area (upper panel), the neutron monitor count rate (middle panel), and the potential gradient (lower panel). The first gray-shaded area corresponds to the 1979 solar maximum, and the second gray-shaded area relates to the 1986 solar minimum
