This has ‘mist’ified me for many years, just what exactly is the difference between Fog and Mist or even Sea Mist?. The stupid thing is, is that I can tell immediately whether it is Foggy or Misty outside but am totally unable to pinpoint when one becomes the other ….if that is possible.
Is it to do with the density of the water particles i the atmosphere, the time of day / night, the temperature…or all three ?
Over to you

RE: Fog / Mist
Fairly frequently in Paphos and Larnaca but only get to spend an hour on the ramp! Would like to take a holiday out there though.

Not that we get much in the way of fog / mist out here you understand…!. Just thought it about time I knew for when I visit next time.

RE: Fog / Mist
[updated:LAST EDITED ON 16-01-03 AT 08:36 AM (GMT)]Good advice from our friend who permanently lives in fog 😉 !!!
In aviation terms there is a clear definition. Visibility 1000m or less is fog, between 1000m and 5000m is mist and 5000 to 10000m is haze.
There are 2 principle ways mist or fog can form defined as Radiation or Advection. Radiation fog is formed typically during the night when the heating of the sun has disappeared and the air cools below the dew point forming condensation which hangs in the air. Advection fog is what is experienced in Guernsey where a warm air stream blows over cooler land which forces the moisture in the air (which has been collected after blowing accross the sea surface) to condense. A notable difference between the 2 types of fog is that Radiation fog needs still air while Advection requires a bit of wind.

RE: Fog / Mist
Good pun on the, ‘mist’ified,’…
The difference is that mist is much thinner and less dense than fog and is formed differently. It depends a little bit on whether you’re talking about mist and fog on land or over the sea. You tend to get mist over the sea in spring and summer as warm air comes up from the Equator bringing lots of moist, warm air. When this hits the cold of the water around the UK, the water condenses out and forms mist. But this mist quickly disappears as the Sun comes up and heats up the air and the sea.
Fog tends to hang around for longer and is formed more by cold, wet air that hangs around and doesn’t move. In a sense it’s like low level cloud and is much thicker.
I hope this clears it up for you…
