I recall a few years ago a what seemed to be ground-breaking white paper from I think a Russian scientist, who argued (and convincingly) that there are two cycles at work, one deep in the Sun, the other shallow. The co-incidence of these two cycles both being at maximum, or both being at minimum, explaining the extremes of solar activity.
- defrost 2y agoThat sounds like Gnevishev, M. N.; Ohl, A. I. (1948). "On the 22-year cycle of solar activity" which first appeared in the Russian journal Astronomicheskii Zhurnal 76 years past.
- casenmgreen 2y agoVery interesting! but not that - it was much more recent, few years ago. What I'm thinking of was not writing about a 22 year cycle; it was arguing for two independent cycles, one deep in the solar atmosphere, one toward the surface.
- defrost 2y agoSure, you more than likely did read a more recent paper. That said, the earlier paper was about two cycles, the already known 11 year cycle and seperate observations that only occurred every two 11 year cycles. There's a chance the two papers are related via a common coupled driver, or not.
