Could I suggest that you (or someone else) now try a patrol from France towards the most northern patrol grids of squares AL or in grid AE south of Iceland? I think you will encounter more persistent bad weather in these areas.

@H.sie:
It seems now certain that the devs altered the time interval for changing the wind speed, according to sea area (probably according to latitude).

If we agree that this principle is correct, that winds and fog should change less often in the north or south, and more often near the equator, then my opinion about duration of wind speed changes is this:

The wind speed should not stick at 15 m/s for more than six consecutive days anywhere. Therefore, since the weather may be checked in some areas only every 2-3 days, it is necessary that the windspeed be reset to (say) 6 m/s after every 3rd call to the windspeed code, if windspeed equals 15 m/s (or perhaps >12 m/s). I have come to the conclusion with recent tests that a random reset of the wind is not good enough, because the random wind may still be > 12 m/s, causing the fog and rain to persist. However, we could introduce a random wind in the new range of 0-6 m/s.

A better solution, perhaps, is to limit the fog to a maximum of 4 days; that is, to cancel the fog after every second call to the fog-creating code. In that case, it will still be necessary to limit the wind, since persistent high winds will cause the fog to return quickly.

Does anyone else have any alternative/better ideas?

@Stiebler I will go for the Arctic asap.

I would like to say my humble opinion about all that:

In the second test I had hat a maximum of 2 consecutive days with 15 m/s.

However, the total days with 15 m/s were 6 from 29 patrol days.

This means almost 21 % of the patrol with 15 m/s. Plus 3 days with 12 m/s or more.

But in my first test, North Atlantic area, only 5 days from 32 with 15 m/s. There, the weather change every 2 days, and not every 1 day like in equator.

This means ''only'' 15.6 % of the patrol with 15 m/s.

Because, the oftener the weather change, the more often the bad weather come again.

So, the problem is not to change often the weather, but to change quicker if bad weahter occur (> 11 m/s).

My reflection is to leave the change speed as it is, but force a quick change if bad conditions occur.

Thank you very much.
