Difference Between Fog and Haze

Main difference

The main difference between Fog and Fog is that Fog is formed by the condensation of water vapors to become water droplets and remain suspended in the air, while Fog is also the suspension of water molecules but with low density.

fog against fog

Fog is the condition in which water droplets are suspended in the upper layers of the atmosphere and cause visibility problems. Fog also causes visibility difficulties, but its extent is very low and it is formed due to the suspension of water droplets in the air at ground level.

Fog is denser in nature and shows a great effect on visibility. Fog is less dense in nature and affects visibility less than fog. Fog allows viewing in an area of ​​less than 1 kilometer (Km) even less than 100 meters. Fog obscured visibility in the area of ​​1 km or more than 1 km.

Fog can be made denser by the addition of smoke and dust particles. Fog can change conditions with changing humidity and temperature. The fog needs more time to disappear and stays for a long time. The mist has a short duration of existence and can dissipate very quickly. Fog shows more resistance to dissipating factors like wind, heat from the sun, etc., while fog shows very low resistance and disappears within seconds.

Fog can be dangerous to mankind and becomes the cause of traffic and shipping accidents. Fog is less dangerous. Foggy conditions prefer the use of vehicle headlights when driving to have a safe trip, while for fog although the visibility is more than fog, the use of headlights and driving at low speed is safe.

Fog Fog
Clouds have a thick nature, made up of water molecules hanging in the air near the surface of the earth. The water molecules suspended in the air due to the sudden change in temperature and humidity.
very dense nature low density level
Things are visible in the one kilometer area. Things can become visible in the area of ​​almost two kilometers or more
Usually exists for a long period Exists for a shorter period
More resistant to the factors that disappear, that is, to the air and the heat of the sun. It can easily disappear in the presence of light and heat from the sun.
Fog has different types depending on the composition. Cannot be categorized into types

What is the Fog?

Fog forms when the air becomes saturated and results in the immediate cooling of water vapors to form visible water droplets. They are the particles of water that hang near the surface of the earth. Fog has some characteristics of clouds like weather, and weather has an impact on fog formation.

Fog formation depends on many factors and therefore can be classified into a few categories. The types of fog are rising fog, freezing fog, and hail fog. The formation of fog due to air rising from the slope of mountains is called upslope fog. The meeting of cold water molecules with the surface causes the formation of ice fog. Hail that is found in areas where there is a presence of hale, and can cause a change in temperature, that is, lower the temperature and humidity, that is, increase the level of humidity.

Fog is the densest in nature, so it has a greater effect on visibility. The high density of fog is responsible for reducing visibility to less than a kilometer. The difference in the conditions of fog formation can also affect visibility, for example, the change in humidity, the mixture of smoke can make the fog denser and the visibility can be reduced to 100 meters or less.

The fog remains for a long time and does not disappear quickly. The fog resisting ability is very strong and can resist dissipating factors for a long time. It does not dissipate quickly with low winds and the heat of the sun. Fog can be dangerous to mankind while driving or traveling.

What is the Fog?

Fog is the natural atmospheric event in which water vapors suspended in the air are dispersed in the environment on the earth’s surface. Sudden cooling of hot air can be a reason for creating fog, and fog can be formed artificially. Fog can occur when a person exhales warm breath in cold weather because fog was formed when hot air comes into contact with cold temperature, so it cannot be further classified.

Fog is less dense than fog and has improved visibility than fog. In fog, the person may be able to see over an area of ​​more than a kilometer. According to scientists, the fog can be described by the visibility in the area of ​​less than one kilometer, and the fog has a visibility of at least two kilometers.

Fog can dissipate more quickly because it is less dense and has a low resistance to vanishing factors such as air and heat from the sun. A light wind can blow away the fog in a few seconds. Fog is considered less dangerous than fog because it allows visibility in almost 1.5 to 2 km of area.

Key differences

  1. Fog is a dense, flat cloud that forms from small water molecules and is suspended in the air near the earth’s surface; on the other hand, fog is the suspension of small water molecules in the air.
  2. Fog has a higher density spread and casts a hazy shadow that disturbs visibility, while fog shows a lower density spread than fog.
  3. Fog reduces the visibility level below 0.6 miles or less than one kilometer; conversely, the fog covers an area of ​​2 kilometers or 1.2 miles.
  4. The duration of the existence of the fog is longer, and it takes time to disappear, it can remain a few minutes, or hours to disappear, relatively the fog has a short duration of existence and can disappear more quickly with some winds.
  5. Fog is more resistant to fading factors, for example sunlight and breeze etc. Comparatively, fog can quickly evaporate as quickly as a few seconds or minutes.

Final Thought

The bottom line is that Fog and Fog differ from each other in their formation and visibility, density and origin. If the visibility is less than a kilometer, then it is fog. And if it is greater than two kilometers it will be known as Mist.
