Another example of Kelvin-Helmholtz instability clouds, different from the ones in the video. n |
It's called Kelvin-Helmholtz instability. A yawner of a scientific name, but the clouds the instability causes can be totally amazing.
Writing in About.com's weather page, Rachalle Oblack explained them this way:
"When two different layers of air are moving at different speeds in the atmospher, a wave structure will often form. The upper layers of air are moving at higher speeds and will often scoop the top of the cloud layer into these wave-like rolling structures. The clouds often form on windy days where there is a difference in densities of the air, such as a temperature inversion."
The video first appeared on Facebook, posted by Darren Springer.
