'Spectacular' Kelvin-Helmholtz wave clouds observed on California coast (in Pacifica) [View all]
https://www.sfgate.com/bayarea/article/wave-clouds-form-in-pacifica-17290572.phpCross-posted to Weather Watchers
Named for scientists Kelvin AND Helmholtz.
The clouds form when there are different wind speeds at different altitudes, and this often happens when air blows up and over a mountain or hill.
