Rainfall vs Sunspot-less days was created by oopfan
A year ago, I read snippets of Ben Davidson's "Weatherman's Guide to the Sun" in which he claimed that there was a correlation between cloud formation and cosmic rays. Apparently, sunspot maxima are correlated with low cosmic ray flux, and sunspot minima with high cosmic rays. The reason given, to the best of my recollection, is that high rates of solar wind during sunspot maxima, combined with the Earth's magnetic field, act to shield the Earth from cosmic rays. So, according to this relationship, cloudy weather is to be expected during solar minima. Currently, we are less than a year into a new cycle. The minimum that we are emerging from was deep, historically speaking.
I went to "World Weather Online" website and grabbed a screenshot of the historical rainfall for Fregenal De La Sierra. On top of that, just below the horizontal axis, I annotated it with the number of Sunspot-less days per year, courtesy of "Spaceweather.com". It looks to me like there is some truth to this. Hopefully this bodes well for RoboScopes in 2021.

Thank you for some proper scientific data on the prospect of the weather improving. I hope that a certain member of the roboscopes staff reads this, then he too can stop chanting. Extract from a very recent email from said person.
Boy, was I getting strange looks from people when I was out walking and doing my best to help out. 0
