- what is 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 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 has affected many human activities, such as shipping, travel, and warfare.
- how fog can be formed?
Fog forms when the difference between air temperature and dew point is less than 2.5 C
Fog begins to form when water vapor condenses into tiny liquid water droplets that are suspended in the air

- radiation fog
- ground fog
- advection fog
- evaporation fog / steam fog
- frontal fog
- ice fog
- freezing fog
- precipitation fog
- hail fog
- upslope fog
- artificial fog
Artificial fog is man-made fog that is usually created by vaporizing a water- and glycol-based or glycerine-based fluid. The fluid is injected into a heated metal block, and evaporates quickly. The resulting pressure forces the vapor out of a vent. Upon coming into contact with cool outside air, the vapor condenses in microscopic droplets and appears as fog.
