Hi Rubini, nice to see you on this forum again. How is the medical course going?
As described in the original 'weather' thread, I completed a full campaign with settings that still can be seen in the NYGM campaign files (now commented out, but similar to those in the original 'weather' thread). Let us call these temporary settings 'test weather' (details below). It was during the campaign that it became apparent that these test weather settings were causing an aggregate increase in extreme weather (heavy fog and/or 15 m/s winds) over the stock model.
Afterwards, I restored the stock settings to remind me of what it had been like before. Fewer extreme weather conditions certainly, but also something else. I noticed with stock settings that high winds and thick fog often 'wrapped around' so that weather might jump from 15 m/s to 0 m/s, and thick fog to no fog. I had never noticed this with the test weather settings, high winds kept falling slowly to less strong winds, then rising again. The same with the fog - always from heavy fog down to medium fog and then down again to light fog or up again to heavy fog. I must emphasise: 'I had not noticed this'; I can't be sure whether a 'wrap around' occurred sometimes.
This seemed to explain why stock weather gave fewer extreme conditions than test weather, and might explain why the Romanian devs used the stock weather. It would have been just as easy for them to use the test weather, if these changes actually worked properly.
The following header is used in all three NYGM campaign files (_LND, _SCR, _RND):

To summarise, then, the 'test' weather produces faster changes of types of weather, compared with stock weather.
However, there is a tendency for the wind speed and fog to keep becoming worse, and the more the weather changes, the greater this tendency becomes. Modifications to the stock weather system seem to result in SH3 providing many storms of short duration, rather than the stock weather of few storms of long duration. In aggregate, stormy days at sea are fewer from the stock system than from the modified systems.
As a result, NYGM campaign files have reverted to the stock system.
I hope that helps.
Stiebler.
