The relationship might be mirrored by Jupiter, whose revolution around the Sun is about the same duration as a solar cycle. And Jupiter has just undergone some kind of radical change in its cloud bands. The Sun and planets all came from the same place, and continue to interact.
I once proposed to Prof. Rob Van der Voo (U. Mich.) that sulphur from volcanoes was analogous to the Io torus, affecting the way in which the Earth receives energy from the Sun. And here's a wild idea: might the Earth influence the Sun? Does Jupiter affect the Sun?

Does Jupiter affect the Sun? Read the work of Rhodes Fairbridge and Landscheidt and all the associated discussion of motion around (or freefall towards) the solar system barycenter. Its possible that these movements affect the Earth/Moon system's orbital velocity and orbit eccentricity and these changes in turn could lead to stresses in the Earth. There are whole threads of discussion around this

One of the great epiphanies of my education was in differential calculus: everything can be expressed as the sum of a series of wave functions. However, one never knows when a rogue wave will strike or when harmonics will cause uncontrolled amplification.

Querying the machine for links between weather and solar cycles gets a 0.999 percent probability that there is.
Querying the machine for links between volcanoes and solar cycle gets a null answer.
Insufficient data.
We do not have worldwide data accurately enough for long enough. However, I suspect there is.

Indeed, I have said many times before that volcanic history data are lacking. My favorite example is Tambora, which had a climate-changing eruption during the Dalton minimum. Due to political unrest, scientists could not monitor the volcano and its last eruption is only known to have been around 1987, plus or minus twenty years. And there are almost no data from undersea volcanoes...
And exactly what does one attempt to correlate? The date an eruption begins or a daily flux of lava? Rate of lava output depends on several factors, but fissure size is perhaps most important. Therefore, I infer that creation of the fissure--or date an eruption starts--is what correlates with solar activity.

Talking [happily?] about volcanoes, perhaps we should open a book on when Katla will explode. en.vedur.is/earthquakes-and-volcanism/earthquakes/myrdalsjokull/Earthquakes now seem to be happening quite regularly on LHS of the caldera. For some reason, I am putting my bet on November [this year!]. This will give the volcanologists and associated climatologists some real data to chew on. The rest of us might just go hungry.
