Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface. [1] [2] Fog can be considered a type of low-lying cloud usually resembling stratus and is heavily influenced by nearby bodies of water, topography, and wind conditions.
With sufficient humidity in the cooler layer, fog is typically present below the inversion cap. An inversion is also produced whenever radiation from the surface of the earth exceeds the amount of radiation received from the sun, which commonly occurs at night, or during the winter when the sun is very low in the sky.
In the air, the condensed water is called either fog or a cloud, depending on its altitude when it forms. If the temperature is below the dew point, and no dew or fog forms, the vapor is called supersaturated. This can happen if there are not enough particles in the air to act as condensation nuclei. [5]
However, that will not happen until later this weekend to early next week. For the fog to become less dense or go away, the difference in temperature between the air and the ground has to diminish ...
The fog season is a season of fog that occurs in some places, because of special meteorological and topographical characteristics, after a rainy period. The fog ...
The National Weather Service issued a dense fog advisory Monday morning for much of South Florida.
Tule fog is a radiation fog, which condenses when there is a high relative humidity (typically after a heavy rain), calm winds, and rapid cooling during the night. The nights are longer in the winter months, which allows an extended period of ground cooling, and thereby a pronounced temperature inversion at a low altitude.
When this happens occasionally, you probably don’t give it a second thought. But when your brain feels like it’s lost in a dense fog all the time, you may start to worry. What you may be ...
