Not entirely sure how the fog works, so this will need confirmation from someone else.
To my knowledge, it’s the distance in feet at which fog starts and ends. The closer together both values are, the denser the fog will be. So Sunny 8,000-200,000 would give you a fog layer that is 192,000 feet wide, which is practically imperceptible.
If you want to have dense fog at 1.5NM (1NM = ~6000ft), you would set the lower value around 9,000 and upper value not above 15,000.About the weather types, it’s pretty much as you say. I think it’s as follows:
Sunny: clear skies, except maybe some stratus
Fair: A few cumulus clouds here and there, but generally good weather
Poor: More cumulus clouds, possibly an overcast but no or light precipitation
Inclement: Definite overcast, with normal or heavy precipitation
I get it, what about when the weather is due to change so now i have it as probabilistic with change every min interval 1800 sec and max 3600…if the weather is sunny (clear when at night) could the weather change to any of the 4 states instantly? so it could go from sunny to inclement? i’d imagine it does as it i have it set at 25% for each weather state (at the moment, but think i might change it).
