Check out this amazing image of a total cloud inversion at the Grand Canyon National Park in Arizona!
This rare meteorological event occurred one year ago today — and it’s something park rangers wait years to see. A sea of clouds filled the canyon because of a temperature inversion, which happens when the air near the ground is cooler than the air above it. A high-pressure system brought low temperatures, clear skies and calm winds to the Grand Canyon.
