  Shallow evaporation fog

  As the early morning Sun warmed wet soil, evaporation saturated the cold air immediately above the ground. Water vapour condensed in the cold air, producing this shallow “steam fog”.

  Evaporation fog

  Evaporation fog is formed when cold, stable air moves over a much warmer body of water. Evaporation from the relatively warm water saturates the cold air above. Water vapour then condenses in the cold air, producing “steam fog”.

  This picture shows evaporation fog, or steam fog, formed over the water of the Grand Union Canal at Harefield in southern England, UK. The air temperature over the surrounding countryside fell by the end of the night to around, or just above, 0 °C. There was mist in some places, but in general radiation fog did not form over fields. However, the evaporation from water surfaces such as streams, rivers and, in this case, canals provided the very localized saturation necessary to form fog.
