Thousands of driving accidents happen each year because of fog.

Superfogs create very hazardous driving conditions.įog and smoke from a brush fire combined to make a super fog, resulting in this massive car accident in Florida in 2008. A super fog is so dense that you would not be able to see your own hand in front of your face. This combination of smoke and water vapor is a dangerous one. The smoke provides particles for the water vapor to condense around. One of the most troubling kinds of fog is called “super fog.” Super fog forms when smoke from wildfires and water vapor come together to form an extremely dense fog. When it comes into contact with cold surfaces such as roads and sidewalks, it instantly forms a dangerous icy layer. In this case, water in the air becomes “supercooled.” This supercooled water is a liquid, but it is colder than the freezing point (32✯). Sometimes it is cold enough, but the air does not have any particles. Ice crystals form in the air when it’s cold enough and particles like dust or smoke in the air provide a “seed” for the ice crystal to form around. Ice fog is common in parts of Alaska and Canada.Īnother kind of fog is freezing fog. Ice fog forms only at extremely cold temperatures. Ice fog forms when the air near the ground is cold enough to turn the water in fog into ice crystals.

There are many different types of fog, too.
