Your quote is from the Air recon section, I understands surface recon as either in a cloud and no visibility or full visibility.
25 000 meters at daytime and 10 000 meters night time.
the meteorological definitions of
fog is visibility < 1 000 meters and
haze between 1 000 and 10 000 meters
And meteorological visibility is how far away you see a easily distinguished object,
a camouflaged small vessel is another story.
So that why I say that Visibility isn't really affected by bad weather.
But it is affected, just as you've described.
Presence of clouds doesn't mean that they extend all the way to the ground. So, the 15/30% figures allow for planes to somewhat fly under the ceiling. Furthermore, air spotting doesn't just spot the ships, it can spot the wakes of those ships as well, which extend multiple times the length of the ship. And a "small" vessel is still huge compared to ground targets, with no way to hide.
Affected by an insignificant margin and all increments in what would be called good weather.
in TOAW visibility is in three steps
The Very best visibility possible - 25 000 meters
Very good visibility - 21 250 meters
Good visibility. - 17 500 meters
to quote wikipedia:
The international definition of fog is a visibility of less than 1 kilometre (3,300 ft); mist is a visibility of between 1 kilometre (0.62 mi) and 2 kilometres (1.2 mi) and haze from 2 kilometres (1.2 mi) to 5 kilometres (3.1 mi).
I think visibility should be reduced to 30% and 15% of the clear visibility.
(or have I misread the text above?)
