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.
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.
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 ...
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.
AccuWeather meteorologists say the biggest weather impact to travel this weekend will likely be the poor visibility. Dense fog recently contributed to a deadly, multiple-vehicle pileup in China.In ...
For the fourth consecutive day, Kansas City was forecast to see its temperatures rise into the mid- to upper 90s while high dew points were expected to make it feel more like 110 to 120 degrees ...
A surface weather analysis is a special type of weather map which provides a top view of weather elements over a geographical area at a specified time based on information from ground-based weather stations. [6] Weather maps are created by detecting, plotting and tracing the values of relevant quantities such as sea-level pressure, temperature ...
Climate experts warn San Francisco's iconic fog is disappearing... and fast. U.C. Berkeley professor explains why this is happening and what can be done to stop it.
