Out of curiosity, I've tried three long patrols in a IXC U-boat using NYGM's campaign files with *stock weather* and small changes made as suggested by LeoVampire (see my earlier post).

I made the following small changes to scene.dat:

Windheadingchangespeed 0.03 (was 0.01)
Windspeedchangespeed 0.03 (was 0.01)
Changetimemin 2.0 (was 3.0)
Randomwindspeedvariation 0.007 (was 0.005)
Randomwindheadingspeedvariation 0.007 (was 0.005)

These settings were a disaster. Wind levels rose from the initial 5 m/s to 15 m/s, and then stuck there for one whole patrol at 13-15 m/s. It seems that the Windheadingchangespeed and Windspeedchangespeed settings need to be lowered (not increased) if the wind is to change more frequently.

So I abandoned the first two changes, and raised the Rainintensity change speed a little.

Now I have the following changes ONLY:

Changetimemin 2.0 (was 3.0)
Randomwindspeedvariation 0.007 (was 0.005)
Randomwindheadingspeedvariation 0.007 (was 0.005)
Rainintensitychangespeed 0.013 (was 0.010)

In two long patrols at tc=1024, these weather changes look really good - no long spells of bad weather, and fairly frequent minor changes. I'm going to stick with these values for a while.

If anyone else wishes to try these values, please share experiences in this thread. But remember - they are random changes. You must complete a long patrol for your results to have any meaning.

One last thing - I just cannot believe Leovampire's assertion in the SH4 thread (quoted above) that weather is dependent on time compression. Even at tc 4096, the game gets updated every 10 minutes or so. Weather changes take at least several hours even to be considered. The devs would have needed to make some pretty eccentric programming to introduce an effect dependent on time compression. Or does anyone else know better?
