Grand Canyon filled with fog, spectacular photos
An unusual sight at the Grand Canyon this morning.
It was filled with fog!
The National Park Service posted the photos below to the Grand Canyon National Park's Facebook page.
A 'Temperature Inversion' was responsible for this awesome sight.
Cold air was locked up in the Grand Canyon with warm air sitting above it.
The warm air acts like a lid, locking the cold air in the canyon and preventing movement and mixing between the two air masses.
The chilly air in the canyon cooled to the dew point and clouds formed, filling the canyon with fog.
The below image is from the Salt Lake City National Weather Service Office.
It shows how inversions work and how pollution in cities can also build up under a cap of warm air.
