Clouds showing a wave-like structure in Washington DC, USA. Wave clouds are known as Kelvin-Helmholtz clouds, after scientists Lord Kelvin and Hermann von Helmholtz, who studied the instabilities that form where there is a velocity difference at the interface between two fluids or fluid layers (in this case caused by different densities of air across a temperature inversion) | |
