The photo above showing Kelvin-Helmholtz instability wave clouds was taken over Vecses, Hungary on June 27, 2007. Altocumulus lenticularis or sometimes cirrus type clouds seem to favor their development. Kelvin-Helmholtz instability is also observed in fluids. In order for this form of instability to occur in either liquid or air, a velocity shear or velocity difference between two layers must be present.
