The ~ 360 year cycles and the subharmonics at 180, 90 and 45 years relate to the Jose cycle of 179 years and repeats of Earth, Venus, Mars, Jupiter lineups at ~45 years. Also hints of solar Gleissberg cycles at around 90 years.
We are homing in on the relevant periodicities. Along with the de vries cycle around 220 years and the ocean air temperature cycles noted by Roger Andrews at around 110 years, we should also keep Harald Yndestad’s lunar tidal cycles of ~74 and 37 years in mind. These relate to Landscheidt’s ‘ big finger cycles‘. I have high hopes that we will soon be at a point where we can better understand the varying lengths of periods of deep solar minima.
