Are there any studies or science behind this? I've read that warm sunny weather is best, which would explain why a lot of creative people reside in Los Angeles. But I've also read that bad weather is better because warm weather is too comfortable and dulls the brain or something. Also, does your environment have any effect on creativity?

I'm a writer and warm sunny weather helps me a lot. I feel like I get writer's block in winter, and then spring comes and I'm suddenly inspired again. But I also wonder if it's my environment. I live in a small village so maybe I only think nice weather helps because it's the only thing to look forward to. Perhaps if I lived in a city or somewhere a bit more happening, I would get more inspiration year-round. Look at a place like Tokyo. People there create a lot of interesting video games and manga and their weather isn't great, but they are in an exciting city.

tl;dr is there any scientific evidence that one type of weather is better for the brain/creativity? What about environment?
