My thanks to Ian Wilson for an update on his tidal-torquing model, which relates the motion of Venus, Earth and Jupiter to changes in sunspot numbers and the flows observed on the Solar surface. This elegant solution looks very promising in terms of forecasting solar variation, as well as offering a hypothesis explaining a mechanism underlying the strong correlations between solar variation and planetary motion. The following article is reposted from Ian’s excellent blog.

Ian Wilson : November 2012

The problem with the collective blog postings about the
Spin-Orbit Coupling or Tidal-Torquing Model that are described
at the end of this post is that they only look at the tidal-torquing
(i.e. the pushing and pulling of Jupiter upon the Venus-Earth
tidal bulge in the Solar convective zone) when Venus and Earth
are inferior conjunction (i.e. when Venus and Earth are on the
same side of the Sun). However, a tidal bulge is also produced
when Venus and the Earth align on opposites sides of the Sun,
as well (i.e at superior conjunction).

This means that in the real world, tidal bulges are induced in
the convective layer of the Sun once every 0.8 years rather
than every 1.6 years, as assumed in the original basic model.
This is achieved by a sequence of alternating conjunctions
of Venus and the Earth:
