[REL]Bad weather fix for SH3

[Hitman]

At northern latitudes, the code changing the weather (specifically, the wind speed) is accessed only very infrequently.

This seems to confirm the notes from the Devs we had, saying that the weather changes less frequently in the artic areas. What we didn't know yet is how it was done, and now we do: The code changing the wind is accessed less frequently. This seems also to indirectly confirm that wind leads most other changes, which is again logical because most storms I have seen in real life were preceded by a sudden increase in wind strength.
