Hello all, it's been ages... I know that there are programs that create artificial worlds fractally. But I'm looking for apps that might create or generate weather to put on those planets, and I can't find anything. Does such a thing exist?

I'm looking at writing a novel set in a fantasy world, and hoping for shortcuts that won't distract me to the point that the novel never gets written. I'm very good at falling down rabbit holes.

Any ideas? Thanks so much!
