How in the world can fog freeze?

Question

All the time I hear people saying that there will be frozen fog? How can fog freeze?

Answer 1

Freezing fog is much like freezing rain as both are at a super cool state. They will usually turn to ice almost instantly when the droplet gets in contact with a cold surface. Fog is just small very small droplets of water. A water droplet will freeze when the temperature surrounding the droplet cools to at or below the freezing temperature level. Both will produce those very dangerous icy driving condition on roads and highways.

Freeze Fog

Answer 3

Water can freeze at 0°C but it doesn't have to. It can stay liquid at temperatures well below 0° under certain circumstances - down to -10° or - 20° or even lower. This water is called "supercooled". Supercooled water droplets in clouds are responsible for the formation of hail and also for the deposition of ice on aeroplanes.

Fog can form in conditions where the temperature of the minute water doplets making the fog is below 0° but the water is still liquid. If the droplets are agitated by blowing them against a surface, they will freeze on contact. It is freezing fog that is responsible for the feathers of rime ice that form occasionally on posts and tree trunks.

Answer 5

[ f o g & m i s t : w h a t i s f o g ? ] Fog is essentially a dense cloud of water droplets, or cloud, that is close to the ground. When night conditions are cold, clear, and calm, the ground releases the heat it absorbed during the day. As the temperature of the ground decreases, it cools the air above it to the dew point (the point at which water vapor condenses into droplets of liquid water), forming a cloud of water droplets known as radiation fog. This is the kind of fog one sometimes sees settling in a valley. Fog also forms when warm, moist air travels over a cold surface. The moisture in the air condenses and forms advection fog, or “land fog.” There is also another type of fog known as sea fog, which is carried from place to place on air currents. This type, which often occurs around San Francisco in the United States, is difficult to dissipate because it continuously forms. Water droplets are only about 0.01 millimeter in diameter. A dense fog contains about 1200 visible drops per cubic centimeter of empty space - barely enough water to wet an object’s surface.

Answer 6

As I understand it. Fog is produced when the air temp is warmer than the ground or water temp. If the air temp should suddenly drop then the water particles in the fog would freeze before they could settle back to the ground.
