What causes fog?

fog is a meteorological phenomenon caused by air supersaturation, so it can no longer hold water vapor. Water vapor is precipitated into small droplets of condensation or fog. The processes are similar to those that produce clouds, although fog is formed near the ground rather than higher in the atmosphere. Since visibility can be limited under vague conditions, attention should be paid to the ride or walking, especially because it tends to damp and distort sound, which potentially does people who do not know about dangers.

At any time, the air reaches the point of extremely high humidity, there is a fog. This happens most often when the air cools down quickly, causing condensation to create. There are a number of types named for the conditions they create. Drivers who navigate in it should use low rays or fog lights rather than high rays, which are simply reflected from water droplets and creates glare.

along the coast of the oceans and the large point of theY passes through the colder surface of the soil. Warmer weather inland often sucks wet air across the ground and creates a thick blanket of fog. This happens most often around the ocean, as salt increases moisture and condensation can form at a much lower level of moisture around the salt.

Another common type is the radiation fog. This type usually occurs in the dark when the ground emits the heat outwards. As the heat rises, it is cooled and causes saturation conditions. The radiation fog usually holds near the ground and disappears until the middle of the morning as soon as the day warms up enough to dispel it. In the central valley of the California there is a variation, tule fog. Tule fog becomes when cold mountain air immerses in depression like a valley at night. Warmer air above it pushes cold air down and causes foggy and persists for days. This type occurs in autumn and winter, when the conditions in the mountains are coldmore.

A rare type called ice fog can only be created in extremely cold conditions, such as the conditions in the Arctic and Antarctica. When the ambient air temperature is basically below freezing, but still moist, droplets of water that would normally form fog, instead turned into small ice crystals. The ice fog can be dangerous for driving because the crystals stick to the windshields and headlights.
