Landscape with Fog. Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface.
Fog is often portrayed in art as a means to evoke mood and atmosphere. Artists use it to create a sense of mystery, tranquility, or melancholy, employing soft edges and muted colors to convey the obscured landscapes and ethereal quality of fog.
Impressionist painters like Claude Monet and J.M.W. Turner captured fog in their works, highlighting its ability to transform familiar scenes into dreamlike visions.
Fog can be considered a type of low-lying cloud usually resembling stratus, and is heavily influenced by nearby bodies of water, topography, and wind conditions. In turn, fog affects many human activities, such as shipping, travel, and warfare.
Fog appears when water vapor condenses. During condensation, molecules of water vapor combine to make tiny water droplets that hang in the air. Sea fog, which shows up near bodies of saline water, is formed as water vapor condenses on bits of salt. Fog is similar to, but less transparent than, mist. The term fog is typically distinguished from the more generic term cloud in that fog is low-lying, and the moisture in the fog is often generated locally. By definition, fog reduces visibility to less than 1 km, whereas mist causes lesser impairment of visibility. For aviation purposes in the United Kingdom, a vis
