That sounds great. Stiebler's patch has a weather fix as well. Have you used that, Utops, or have you always played h.sie's fix?

Only h.sie hard code fixes patch because it works for me like it should. Maybe in next career i
add up stieblers fix as well.

As for weather fix it not always update weather condition, after 3 hours of game time. But in example in november 1940 grid DH i've got stormy weather and after 3 h it was still rough, but i was able to reload torpedos and after next 3 hr storm is back in full power 3 h later water was calm but heavy dark clouds remain.

That sounds the kind of weather I would love to have. I guess I should opt for h.sie's weather. Stiebler's patch gives an option to choose h.sie's weather instead of Stiebler's own weather patch.

Stiebler's patch does not have a weather fix. Only H.sie's patcher V16B1 has a patch to fix the weather. h.sie's patch is meant to be used in conjunction with a modified envsim.act file (dated 2/18/2012) which h.sie supplies in his V16B1-patch-kit. Stiebler provides a different version of envsim.act (dated 11/12/2014) also intended to be used only in conjucntion with h.sie's Weather Fix patch. I use Stiebler's version and it works fine. I have used h.sie's version also, although Stiebler says the newer version is superior.

There is a third version of envsim.act (dated 11/24/2011) which Stiebler included in NYGM 3.6E. According to Stiebler, this version can be used without h.sie's patch. It is intended to work with any SH3 setup. I haven't tried it.

I wonder if I have a glitch in my system. With Stiebler's envsim.act I get at least 2 - 4 days of the weather staying the same. I don't seem to get the 15 m/s storms all the time, though. I now took Stiebler's envsim.act out of my system to experiment with h.sie's envsim.act.

No help. The same thing with h.sie's envsim.act too. Not even a slightest change in the weather for two and half days of test cruising.

I've tried to change the weather change frequency myself. This is one thing I've changed:

Does anybody know if my values are all wrong here?

I know it doesn't solve the weather problem but this mod by Jimbuna should solve the not being able to use deck guns in heavy weather problem. http://www.subsim.com/radioroom/down...?do=file&id=32

A couple of considerations:

The SH3 weather model just doesn't permit short term fluctuations, like a one-hour rain squall. If you are getting 2-4 day periods of the same weather with good variation between the periods, that's probably as good as you can expect. If you have 1 or 2 4-day periods of bad weather in a 30-40 patrol, that's not bad.

But the weather in SH3, in spite of all the impressive graphics, is really not all that bad. The worst weather possible is 15 m/s, about a 30 knot wind. That's a 7 on the Beaufort scale, what the World Meteorological Organization calls a Near Gale. Not a full Gale (Force 8) and a long way from a Storm (Force 10), which has winds of 55 knots. Wave heights should be 4 m, not enough (I think) to completely submerge the turm. Four days of Force 7 winds in the winter North Atlantic? Yeah, okay.

One big problem is that stock SH3 says that storm conditions start at 7 m/s. That's 13 knots, Force 4, a Moderate Breeze! I have never had the pleasure of trying to man a deck gun under those conditions., but I've worked a 35 foot sailboat in Force 4, and never once was I in fear for my life.

NYGM at least raises the storm conditions to 11 m/s. That's still only Force 5, a Fresh Breeze. On a low-freeboard submarine that might be a tad dangerous, but it's hardly beyond human capability.

So raise the storm level to 11 m/s (or higher) and go after them. You're just not going to get a lot of clear, calm, sunny days in the North Atlantic.

I see. It might be I already have the best I can get. What I would like to see, is as realistic weather as possible. Instead of 15 m/s wind for 48 hours a change from 14 to 15 to 17 to 13 to 15 m/s, back and forth during that48 hours. I don't mind bad weather. What I hate is the the monotonousness of the weather. There's not even the slightest change in wind direction for tens of hours.

Having made some quick experiments today it seems I can't get any responses from the system if I change scene.dat.

However changing envsim.act had a positive change. When trying h.sie's Weather Fix Yoriyn Edition I had one weather change in 48 hours of x1024-x2048 TC.

The biggest change I was able to achieve by editing the campaignxxxx.mis files.

FogRand=1
Clouds=0
CloudsRand=1
Precip=0
PrecipRand=1
WindHeading=5
WindSpeed=5.000000
WindRand=1
WeatherRndInterval=2

These values brought several weather changes in 48 hours. I've yet to try this setup in a x128 TC patrol, though. It could be that these values don't work in a real test.

If someone else wants to fiddle with their setups, here's the rest of the testing info that has an effect on weather:

- NYGM
- h.sie v16b
- Stiebler 4C (and its envsim.act)
- campaign patrol
- testing area Bay of Biscay
- TC 1024 - 2048 used (not sure if this has an effect)

I'll keep a war diary on my next patrol, and will check weather every four hours. I'll release the war diary in the Tell us what... thread, and you can then read yourselves about the experiment. I'm not too hopeful, as weather has always been one of SH3's biggest flaws. (If one reads the KTB's of the real U-boats the weather is always a little bit different every time they record it to the KTB - and I for one would love to have real storms, but apparently the game engine can't take it.)

That's the main reason I use SH3 Commander's version of the old Big Waves Mod. Depending on the time of year waves can appear to be twice as high as they are in the stock storm conditions. In my hand-written log I factor that in and get conditions that can seem like a real storm. :sunny:

If it works at high TC, then intuitively I'd expect it to work as well or better at lower values. I'll be eager to see how your test turns out.

It's been said on this forum that weather change is tested every 3 hours. If you make an observation every 4 hours, you will be out of sync and could potentially miss a lot of changes. Maybe every 3 or 6?

Good luck. I hope your approach works.

Doesn't look too good. I just had about 4 days of totally constant weather. When I finish this patrol I'll try the Yoriyn envsim.act during a full patrol.

I will! :up: Do you have the link to where this patch is? I'll try finding it myself but send it anyway in case I get lost :oops:

From one extremity to another: Yoriyn weather fix changes the weather too much. The wind keeps rotating clockwise, maybe in a day all 360 degrees, and the weather goes from 0 to 15 m/s winds and back in a day or two. The weather is different every time I have a look at it.
