Q
Visibility expression: >800 >5000 5km - >30km 30km - >70km =<70km
A
>800m = 50m >5000m = 100m 5km - >30km = 1km 30km - >70km = 5km =<70km = Greater than 70km
3
Q
Fog
Mist
Haze
A
Fog = Visibility below 1000m Mist = Visiblity not less than 1000m Haze = Visiblity not less than 1000m & relative humidity is less than 95%
