- Radiation Fog. Radiation fog forms at night when the surface cools, causing the air above it to cool as well. If the air has enough moisture, this cooling will lead to saturation and form fog.
- Advection Fog. Advection fog forms when warm, moist air moves over cooler ground or water. It is relatively shallow and often associated with an inversion.
- Upslope Fog. Upslope fog forms when moist air flows upward over rising terrain, causing it to cool adiabatically to its dew point temperature. “Adiabatic” is a word used to describe the process that causes rising air to cool and sinking air to warm.
- Steam Fog. Steam fog, also known as evaporation fog, forms when cold air comes into contact with warm water. The warmer water evaporates into the cooler air above, increasing the air’s moisture content.
Sea smoke and steam devil over the Sea of Japan on December 25, 2021, on the south of Primorsky Krai of Russia, from Yuzhno-Morskoy (near Nakhodka). Sea smoke, frost smoke, [1] or steam fog[2] is fog which is formed when very cold air moves over warmer water. Arctic sea smoke[3] is sea smoke forming over small patches of open water in sea ice.
May 10, 2019 · The thin, warm, moist layer of air over the pond then mixes with the cooler air from the land. As it cools, condensation occurs and a fog forms. It looks like steam rising off the water, hence the ...
Steam fog forms when cold air moves over warm water. When the cool air mixes with the warm moist air over the water, the moist air cools until its humidity reaches 100% and fog forms. This type of fog takes on the appearance of wisps of smoke rising off the surface of the water. The other type of evaporation fog is known as frontal fog.
Steam Fog, also known as Steaming Fog, Evaporation Fog, Frost Smoke, Sea Smoke or Arctic Sea Smoke, occurs when evaporation takes place into cold air lying over warmer water. It is usually quite shallow. Steam Fog should not be confused with Advection Fog which is formed in warm moist air over a cold surface. Steam Fog is named by analogy with ...
Nov 18, 2019 · Steam devils are swirling columns of steam fog (analogous to dust devils) that look like a whirlwind of steam fog on a cold day. Steam devils can rise up to 1,500 feet above the lake. One of the many features of living near large lakes is that they are often shrouded in a fog in the fall and early winter.

Sep 29, 2021 · Steam fog forms where a cold air mass moves over a warmer lake or smaller body of water. Once this happens, the water will slowly evaporate and add moisture to the air right about the surface. The ...
