Why do we have fog in the morning?

Answer: Fog forms in the morning because it is the coolest time of the day when the temperature drops to the dew point temperatures and the relative humidity approaches 100%. There are instances where dew points rise to the air temperature but common morning fog is created as the atmosphere cools.

What is an advection fog?

“Advection fog” forms when relatively warm air moves over a colder surface (for example: a. body of water snow-covered ground etc.) and the interaction between the two results in the air becoming saturated. The term “advection” just means that the fog formed due to an air mass being transported by the wind.

How do you predict fog?

If skies then clear and wind is light fog is very likely. Fog requires a mixing action by wind without wind dew will appear instead of fog. If the surface is near saturation a light wind will allow for the layer of air near the surface to remain near saturation.

Is fog bad for your lungs?

What causes fog to go away?

Fog often dissipates with daylight. This is sometimes referred to as the fog “burning off” but that analogy is not correct. When the sun rises the air and ground warm up. This leads to the air temperature being warmer than the dew point temperature which causes the fog droplets to evaporate.

Do fog machines leave residue?

Yes they do. Smoke particles settle on all surfaces and may leave a residue. Whether that residue is enough to cause a problem is dependant upon the density of smoke the duration of the effect the type of fogger or hazer and the type of fluid used.
