Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface. [1] [2] 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.
The signal, which would normally be refracted up and away into space, is instead refracted down towards the earth by the temperature-inversion boundary layer. This phenomenon is called tropospheric ducting. Along coastlines during Autumn and Spring, due to multiple stations being simultaneously present because of reduced propagation losses ...
This high-level cloud genus does not produce precipitation. [42] Genus cirrocumulus (Cc) – this is a pure white high stratocumuliform layer of limited convection. It is composed of ice crystals or supercooled water droplets appearing as small unshaded round masses or flakes in groups or lines with ripples like sand on a beach.
A fog desert is a type of desert where fog drip supplies the majority of moisture needed by animal and plant life. [1] Examples of fog deserts include the Atacama Desert of coastal Chile and Peru ; the Baja California desert of Mexico ; the Namib Desert in Namibia ; [ 1 ] the Arabian Peninsula coastal fog desert ; [ 2 ] and a manmade instance ...
Super fog and smog are both types of fog, according to the National Weather Service. But smog — often a problem in cities with heavy car traffic or industry — is formed when fog combines with ...
Cloud physics is the study of the physical processes that lead to the formation, growth and precipitation of atmospheric clouds. These aerosols are found in the troposphere, stratosphere, and mesosphere, which collectively make up the greatest part of the homosphere.

Thus, fog and mist are not precipitation; their water vapor does not condense sufficiently to precipitate, so fog and mist do not fall. (Such a non-precipitating combination is a colloid.) Two processes, possibly acting together, can lead to air becoming saturated with water vapor: cooling the air or adding water vapor to the air.
