Bay 12 Games Forum

Been looking over the feature list and powergoals, ad I got curious about a line:

"A dynamic weather model tracks wind, humidity and air masses to create fronts, clouds, rain storms and blizzards."

Just how dynamic IS the weather? In adventure mode, I've seen clouds roll along, and seen different storms. In fortress mode, It can periodically rain, and in evil biomes, it gets fun.

But I guess my question is, does the game track the *current* temp of the tiles/embark tiles/region tiles to make its calculations, or does it just use the one premade from worldgen?
Meaning, that if I filled up the surface with lava in fortress mode, would/could  that change the temperature/weather calculations at all?
Do volcanoes change anything ingame?

Because If that were the case, it would be interesting to see if a series of Moholes could attempt to change weather patterns, especially in the upcoming release allowing retired forts.

I exist in a seasonally freezing biome with an aquifer and just discovered that my (Planned to be main)stairs happen to lead directly to an area that, well, happens to have the aquifer present. My stairs are inside, as I dug into the side of a hill. If i dig upwards I can open them to sky and I was wondering if that would then allow them(The miners) to dig down through the aquifer whilst it freezes. Or am I completely wrong? I'd love to know if I can somehow punch through it easily without the usage of the other methods such as plugs and pumpstacks.

I'm not that new to DF but I'm essentially completely unfamiliar with aquifers. I forgot to turn them off when I genned the world. Woops.

Edit:It also appears to be a 2(Or more) layer aquifer.
Another Edit: Well, it doesnt seem to do anything having downward stairs at ground level, other stairs are still counted as inside. welp.
