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 amount of water that can exist as vapor in a given volume increases with the temperature. When the amount of water vapor is in equilibrium above a flat surface of water the level of vapor pressure is called saturation and the relative humidity is 100%. At this equilibrium there are equal numbers of molecules evaporating from the water as ...
The phenomenon is called fog if the visibility is 1 km (1,100 yd) or less. In the United Kingdom, the definition of fog is visibility less than 100 m (330 ft) on the surface for driving purposes, [2] while for pilots the distance is 1 km at cruising height. Otherwise, it is known as mist. A rainbow formed from the water spray at American Falls
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 liquid water is the droplets on the outside of your windows, the fog clouding your glasses and the haze visible in the morning. What does the current high heat and humidity mean for Kansas City?
The expanding shell of gas forms a supernova remnant, a special diffuse nebula. [25] Although much of the optical and X-ray emission from supernova remnants originates from ionized gas, a great amount of the radio emission is a form of non-thermal emission called synchrotron emission. [25]
Mist in an airplane cabin often gets mistaken for smoke and can cause anxiety or panic among passengers. Here’s the science behind it and why it’s perfectly harmless.
