A Virginia lady captured a dazzling cloud formation above Smith Mountain, resembling a popular painting by Van Gogh.
Amy Hunter saw the Kelvin-Helmholtz waves, which usually form on breezy days because of specific atmospheric conditions – and resemble waves tumbling across the sky.
The amazingly rare phenomena happen when two distinct layers of air in the environment are moving at various rates – which is known as shear.
Very cool clouds rolling over Smith Mountain this evening. They are called Tsunami clouds. I sent the photo to our…
At the point when the upper layer of air is moving at a higher speed than the lower level air, it may scoop the top of an existing cloud layer into these wave-like rolling shapes.
One model is wind blowing over water, in which quick moving air can make the waves on the slower-moving water.
The occurrence is named after two meteorologists, Lord Kelvin and Hermann von Helmholtz, who studied the physics behind this cloud formation in the 1800s.
