Interesting. The cycle of human activity during the week, particularly when the production of air pollution is higher, may cause more instances of rainy weekends in some parts of the world.
Evidence has been mounting over the years that the weather in certain parts of the world, including the US, Japan and China, can be driven by the weekly cycle of human activity. This is because we tend to produce more air pollution during the week and less at the weekend. Evidence that such an effect occurs in Europe is controversial and has been harder to come by.
