In honor of World Meteorological Day, the 2017 theme is about clouds. This entry will discuss fog vs mist. Why?

Fog can be described as a cloud that touches the ground. It is not like what you would see in the sky. Fog is comprised of cloud water droplets. Those droplets are suspended very close to the earth’s surface.

What differentiates fog from a regular cloud is the fact that fog is very low lying. Regular clouds are further away from the earth’s surface.

Mist is also low lying, very close to the earth’s surface.

What is the difference between fog and mist?

VISIBILITY. Remember this. If visibility is less than 1 km, that is fog. In the UK, fog is defined by a visibility less than 100 metres.
