Where does radiation fog occur?

Asked by: Paul Rivera

Radiation fog is usually patchy, tends to stay in one place and goes away the next day under the sun’s rays. Thicker instances of radiation fog tend to form in valleys or over calm bodies of water. A special kind of radiation fog, called “tule” (TOO-lee) fog, occurs each winter in the Central Valley of California.

Where can fog be found?

When the moist, warm air makes contact with the cooler surface air, water vapor condenses to create fog. Advection fog shows up mostly in places where warm, tropical air meets cooler ocean water. The Pacific coast of the United States, from Washington to California, is often covered in advection fog.

Where does fog come from?

Fog develops when water vapor — the gas form of water — condenses. As it condenses, the water vapor molecules combine, which in turn form water droplets that hang in the air, according to National Geographic. The droplets are what make fog visible, because water vapor, like all gases, is invisible.

How does radiation fog occur?

Radiation Fog: This fog forms when all solar energy exits the earth and allows the temperature to meet up with the dew point. The best condition to have radiation fog is when it had rained the previous night. This help to moisten up the soil and create higher dew points.

Where does fog happen the most?

Fog is frequent along the windward sides of mountain ranges, such as those along the western side of North and South America. Near these mountains, fog is more common where moisture is abundant, and this is controlled by regional patterns in winds and ocean currents.

Does fog come from the ground?

Fog forms only at low altitudes.

They can be as high as 12 miles above sea level or as low as the ground. Fog is a kind of cloud that touches the ground. Fog forms when the air near the ground cools enough to turn its water vapor into liquid water or ice. There are many different types of fog, too.

Why does it get foggy at night?

As the air cools during the longer night the relative humidity increases, which can result in to fog formation.

At what time of day or night is radiation fog most likely to occur?

A radiation fog has initiation, growth, maintenance, and dissipation stages. It is most common during the early morning hours and during the cool season (Croft 1997).

What situation is most conducive to the formation of radiation fog?

What situation is most conducive to the formation of radiation fog? Warm, moist air over low, flatland areas on clear, calm nights.
