(ORDO NEWS) — An eyewitness took amazing photos of a rare cloud formation moving along the horizon as if it were huge ocean waves.
A phenomenon known as the Kelvin-Helmholtz instability was observed over the Big Horn Mountains from Sheridan, Wyoming.
The phenomenon of Kelvin-Helmholtz instability occurs when there is a difference in speed between two immiscible surfaces “moving” over each other. In this case, the faster airflow moves over the rising air below.
The natural formation is named after the scientists Lord Kelvin and Hermann von Helmholtz.
