Fog typically develops when the air near the ground becomes saturated with moisture, causing water vapor to condense into tiny water droplets. This often occurs in the early morning or late evening when the temperature cools and reaches the dew point, resulting in reduced visibility. Other factors such as calm winds and clear skies can contribute to fog formation.
Fog is common in cities due to the presence of moisture, urban heat, and varying temperatures. Cities often have higher humidity levels from various sources, such as water bodies and drainage systems. Additionally, urban heat islands created by buildings and pavement can cause temperature inversions, where warm air traps cooler air near the ground, leading to condensation and fog formation. These factors combined create ideal conditions for fog to develop in urban environments.
The four types of fog are radiation fog, advection fog, upslope fog, and evaporation fog. Radiation fog forms on cool, clear nights when the ground loses heat rapidly. Advection fog occurs when warm, moist air moves over a cold surface. Upslope fog is formed when moist air is forced to rise up a slope or mountain. Evaporation fog occurs when air near the surface is cooled to its dew point by evaporation.
Steam fog is fog that that comes off of water. It comes up when it is really ht outside.
The fog that results from the nightly cooling of the earth is called radiation fog. It forms when the ground cools rapidly, causing the air near the surface to cool and reach its dew point, leading to condensation and fog formation.

A freezing fog advisory is a weather alert issued when fog is anticipated to develop at below-freezing temperatures, leading to the formation of ice on surfaces. This can create hazardous driving conditions due to reduced visibility and slick roadways.
Advection fog forms when warm, moist air moves over a cooler surface and cools down to its dew point, causing condensation and fog to develop. This type of fog is common along coastlines where warm ocean air moves over cooler land areas.
Planes can fly in fog. But the pilots are not able to see properly. This could lead to accidents. In general, there are limits regarding visibility and aircraft operations. Airports have been shut down because of fog. There is work underway to develop an infra-red TV that will display the view on the Heads-Up-Display (HUD) so that the pilot can "see" through fog just as if it was a moon lite night.
Freezing fog, advection fog, and evaporation fog!
Fog can be especially prevalent in coastal areas, near bodies of water, and in valleys. These areas are more likely to experience fog due to the presence of moist air and temperature inversions that trap cool air near the surface.
Blowing ice crystals hamper visibility during blizzards in Antarctica. There is not enough humidity -- less than five percent -- to develop fog.
London fog : radiation fog enhanced by pollutants. Wisconsin fog : evaporation fog near water.
Pea soup fog is fog that is extremely thick, or heavy.
The substance that goes into a fog machine to create the fog effect is typically a special type of liquid called fog fluid or fog juice. This liquid is heated up inside the fog machine, turning it into a mist or fog that is then released into the air.
