Is there a program -- free or paid -- that allows you to basically draw an imaginary landmass and plop some mountains on it and then will tell you "what's the climate downwind of these mountains" or "where does it snow and rain on this landmass"? Smashing tectonic plates together to get volcanoes and mountains would also be nice.
Just kinda want to experiment with making biomes etc. based of landmasses, and two of my kids are studying biomes right now so I feel like it'd be extra-educational for them, as well as fun for me. I'm finding lots of utilities for drawing maps that bear no relation to reality, but I want to be able to realistically smash landmasses into each other and see how mountains affect things downwind and so on!
