There are currently two ways to make changes to the weather, manually or with Skweetis' SH3 Weather program. You can use Skweetis' program in port, just before starting a mission; you can set your own weather settings, or allow the program to make random changes. However, this only works at the beginning of your mission and is set until you start a new patrol. Most likely, your weather
will change, but you will not have any control over it.
Personally, I like to change the weather myself. To make changes manually, and in the middle of a patrol, you need to edit a few text-files (easy to do). Open your Ubisoft/SilentHunterIII/data/Campaigns/Campaign folder and change the highlighted text in
each of these files: Campaign_LND.mis, Campaign_RND.mis, and Campaign_SCR.mis :
[Mission]

where Fog can be set to 0-3 (none, light, medium, heavy), Clouds 0-2 (none, medium, heavy), and Precip 0-2 (none, medium, heavy). The "xxxRand=" settings control the degree of change and can be set to 0-2 (none, minor, extreme). Finally, WeatherRndInterval (maybe the most important variable) controls how rapidly the program will check to "change" the weather. This value can range from 2 to 96, but I never set it above 7 or 8 because values higher than that makes the weather change too slowly for my tastes.
Finally, note that the frequency that you save seems to effect weather changes. When you save, the game resets its timer for weather changes to zero, with the result that the more saves you make, the more likely you are to have unchanging weather.
