[REQ] Realistic climate zones?

[Safe-Keeper]

Found this while looking through SH5 files. It's called "Climatezones" and it's found in the Env subfolder.

In a cfg file in the same folder I found this:

Color00=PolarClimateNorthern
Color40=TemperateClimateNorthern
Color80=TropicalClimateNorthern
Color120=TropicalClimateSouthern
Color160=TemperateClimateSouthern
Color200=PolarClimateSouthern

Looking deeper into this, it seems this controls textures as well as not only weather but also seasons - the temperate zones have four seasons, while the tropical and polar have only one. Seasons, in turn, seem to control only min and max duration between weather change, and min and max wind speed at the moment.

Wouldn't it be possible to tweak the zones so that the Gulf Current and other factors are taken into account? Greenland and Alaska should not have the same climate as Scandinavia, for example, and seasons should be different (fall in temperate zones should have far more rain/snow than the other seasons, for example).

For reference, here is an image showing the world's actual climate zones. SH5 may not need be this detailed, but simple tweaks such as shifting the northern hemisphere (Canada, Siberia, Alaska, and so on) into a colder climate than mainland US and Europe would be a good start. In the future, we could implement things like a rain-heavy monsoon seasons for Eastern patrols. Game seems to allow as many climate zones as there are colour gradients, so there's a lot of potential here overall.
