- - More Variable Weather??!! (https://www.subsim.com/radioroom/showthread.php?t=125259)

snwcrsh--The frequency that the weather changes appears to depend on a couple of factors: 1) WeatherRandInterval setting (conflicting evidence on this, some say this has an effect, others no effect, some say it has a random effect. I place myself in the third category). 2) Patrol base. For whatever reason, weather changes twice as quickly if you leave from Kiel than if you leave from Wilhelmshaven, even if you patrol the exact same area! I imagine the other bases have their own "peculiarities."

John O--We've hit a glitch regarding the weather fix, not sure if we will be able to release a mod that will significantly effect the weather algorithm set by the devs. While our changes seem to have some minor effects, we (so far) have not been able to overcome the restraints set by the game engine. However, we haven't given up yet!

difool2--I have observed some variability, too regarding when the weather pattern changes. In general, when leaving form Kiel early in the war (starting port seems to have an effect for some reason), my weather usually first changes in about 32 hours with WeatherRandInterval=2. However, I have also seen the weather change as early as 12 hours and as late as 72 hours from port, as well. So, there is some randomness built into this number, apparently.

I have gotten to be pretty good at catching the weather change "in the act" :oops:, so to speak. In general, you can watch the wind direction slowly change over a period of a couple of hours. Wind speed, however, changes quickly (within a few minutes), and frequently "pegs" at 15 m/sec, especially because rain automatically increases the wind speed by 7 m/sec. I am currently trying to slow the wind speed change down a bit, but without much success, so far. :shifty: Clouds, rain, and fog change almost immediately.

I also agree with you about the Partial clouds. Would be nice to have more variability in partly cloudy conditions. Also a shame it turns up as the least likely cloud cover, as I think it is the most pleasing.

Thanks for the feedback, guys!

I always thought that the weather in the Mediterranean is different in SHIII - shouldn't it then help to use the milder Med weather for the rest of the world? There are still a lot of storms in the Med, in the Atlantic it's overkill, and along the equator the weather is complete rubbish.

Shouldnt that be a possibility?

Thanks for the update and good luck. Hope you guys lick it.

Great thread! :up:

:hmm:

Is possible to cancel the worst fog conditions? Because every time that I have to catch a convoy or a taskforce and the weather turn horribly foggy and rainy, i risk a nervous crash:damn: .
Just to cheat a bit:up:

For me, the most annoying thing is the 15m/s wind if you play with the stabilizer off, and the tweaks (many mentioned above and in other threads) haven't solved this problem for me.
If one could read and write to the saved game file where the weather info is stored, then all of the problems would go away.

I was unnecessarily gloomy about progress in a previous PM to Subtype Zero, hence his pessimism above. My apologies for that.

Actually, we have made good progress, and we hope to have a new mod 'RealWeatherFix' available after further testing.

Stiebler.

Nothing new to report yet but with further testing, I've noticed that leaving from Wilhelmshaven, about 90% of the time, when I cross up into the grids (longitude) of where Scapa Flow is, the winds almost always change directly to 15 meters per seccond and all hell breaks loose (After reading the above post about the windspeed increment multipliers, it's possible that I always reach these coordinates just as the change kicks in. To test this, I'll change the windinterval or whaterver that number is a little and see what happens). I think I've narrrowed down somewhat the location of one of the weather change latitudes. What I'm going to try to do is try to drive above and below it to see if there's a line that produces a change.

It could be that the weather is set to be the same along groups of grids also. Something to consider.

This is going to be tough to really test well.:nope:

I can confirm this observations. Left two patrols from Wilhelmshaven with calm winds (4 or 5 knots). Changed to 15 after Scapa and stayed this way for two weeks all over the atlantic (no change whatsoever)

Gnørf. Especially annoying, seeing as 15 m/s is no big deal in the north sea. 20, or 25 (steady for an hour or two) as we had yesterday on the coast, is more like it.

It can stay at 15 m/s for days at a time. That's commonplace. 30+ steady is exceptional. 20+ is uncommon, but seen several times every autumn/winter.

... west coast of norway.

I think something may be broken with the randomised die roll for the weather. I've noticed also that the weather tends to either be 15 meters per seccond or near dead calm up to 5 meters per seccond. It's rarely in between that.

Either that or I have another theory. Perhaps it's possible that each zone has it's own set of chances or modifiers to the die roll for different kind of weather that play into the factor. Up by Scapa Flow may have a high modifier to the die roll to make it tend more toward stormy weather whereas down south near Gibraltar, It seems to be about even between calm lightly stormy.

I can definitely say that the zone around Scapa seems to produce the most storms in my experiences.

would it be possible to be caught in a hurricane, or see a windfunnel (tornadoe on water, made of water):rock:

I make some tests on the WeatherRndInterval variable. A use different numbers each time when i start new career (12 tests). I start each campaign 1 september 1939 in first flotilla in Kiel.
Everytime first weather changes have a place after 32h, second after another 33h, third 34h, fourth 35h...

Test raport:

I random save the game during tests.
Saving during patrol do not affect to weather changes, but after save and quit the game, when you load the patrol weather timer is reset (you must wait 32h before weather change)
example:
last weather change have a place 2:00am 5/09/1939 so another shut be (32h) 10:00am 6/09/1939. But when you save and exit, lets say 18:00 5/09/1939, weather changes will be 2:00am 7/09/1939.

WeatherRndInterval variable, I use numbers from -11 to 96.
Weather allways change after 32h, it's not dependant on the WeatherRndInterval value.
WeatherRndInterval < 0 weather do not change for lots of days (stay the same), only wind changes observed. For this value weather was allways rainy and foggy.
0<WeatherRndInterval<12 weather changes are most realistic (no hard weather changes)
WeatherRndInterval>12 drastic weather change everytime (from big storm to wind 0m/s, and again big storm).

I suppouse after tests, the WeatherRndInterval variable respond for:
"How many weather checks the weather will be the same. The biger value the less chance the weather stay the same in the next weather check (32h)."
And "Biger value of the WeatherRndInterval, the weather change more drastic"
