Predicting solar cycle modulation using angular momentum is relatively easy, but like any prediction it needs to be tested. Interested parties who rely on solar activity predictions might like to make a copy for future reference and compare with the regular methods of prediction which typically only go out for one cycle, which can hamper long term planning in some industries.
One thing we cannot predict is solar cycle length, so this prediction is more about modulation rather than precise timing of upcoming solar cycles. One other factor in play is whether “Wilson’s Law” will contribute to future grand minima, by 2190 I predict we will know the mechanics of this law. As can be seen here and on the 11000 year 14C graph there are no high solar activity peaks at times of low angular momentum.
There is a possible case for a repeat of the 1870 type reduction in solar activity at 2050, but this time around the disturbance is very weak as the Jupiter/Saturn angles continue to weaken. On most occasions we are presented with 3 disturbances per cycle but in the current cycle we may only get 2, SC28 & SC29 remain the subject of more research.
Below is Carl’s now famous original graph showing angular momentum in a different form. The green arrows showing times of angular momentum disturbance.
