Sea smoke, also called steam fog or evaporation fog, is created by cold air passing over warmer water or moist land. [24] It may cause freezing fog or sometimes hoar frost. This situation can also lead to the formation of steam devils, which look like their dust counterparts. [29] Lake-effect fog is of this type, sometimes in combination with ...
Sea of fog riding the coastal marine layer through the Golden Gate Bridge at San Francisco, California Afternoon smog within a coastal marine layer in West Los Angeles. A marine layer is an air mass that develops over the surface of a large body of water, such as an ocean or large lake, in the presence of a temperature inversion.
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. [4] It forms when a light wind of very cold air mixes with a shallow layer of saturated warm air immediately above the warmer water.
A steam devil is a small, weak whirlwind over water (or sometimes wet land) that has drawn fog into the vortex, thus rendering it visible.They form over large lakes and oceans during cold air outbreaks while the water is still relatively warm, and can be an important mechanism in vertically transporting moisture.

The lower temperature causes water vapor to condense into tiny liquid water droplets which are heavier than the air, and which fall unless supported by an updraft. A huge concentration of these droplets over a large area in the atmosphere becomes visible as cloud , while condensation near ground level is referred to as fog .
The decline in fog is generally attributed to climate change, and is concerning for the local ecology, for example the redwood trees. [12] Climate change contributes to the warming of our oceans, directly resulting in less fog as ocean water is not cold enough to mix with hot, moist air currents to create fog. [13]

This can occur when, for example, a warmer, less-dense air mass moves over a cooler, denser air mass. This type of inversion occurs in the vicinity of warm fronts, and also in areas of oceanic upwelling such as along the California coast in the United States. With sufficient humidity in the cooler layer, fog is typically present below the ...
