OMAHA, Neb. — According to the National Weather Service, there are six different types of fog. KETV meteorologist Luke Vickery looked into radiation fog and how it forms.

Radiation fog, the most common type of fog, occurs when cool temperatures, high humidity and low winds combine. According to the Bureau of Meteorology, it most commonly forms overnight when the ...

Fog is formed when water vapor condenses into droplets in the air, and the most common types are radiation fog and advection fog, among others, which are formed under different weather conditions.

Radiation fog forms overnight on clear, calm nights when the ground cools rapidly and chills the air near the surface to its dew point. A stunning reversal of fortunes in Canada's historic ...

Radiation fog is very common. This fog develops under clear skies and calm winds. As the earth emits radiation at night, the surface air cools off.

Types of fog and their formation Radiation fog is when the ground is colder than the environment. It generally happens at night when the ground cools due to heat loss from the sun.

Radiation Fog: This is the most common type. The ground cools rapidly at night, losing heat to the sky.

On Saturday, melting snow caused by the rain cooled a warm air mass to saturation, causing the fog. Also on Saturday, there was a break in the clouds that allowed for radiation fog.

Unlike radiation fog, skies don’t need to be clear for advection fog to develop, and the sun can’t really burn it off. Advection can also persist even in the presence of a breeze.
