Abstract Ultra-high resolution (2m) radar observations show the amplification of unstable Kelvin-Helmholtz (KH) waves, the development of roll vortices, their breaking and the resulting turbulence, and appear to represent our first view of the life cycle of clear air turbulence. The KH waves are initiated at the base of an inversion at which the Richardson number, Ri, is slightly positive just prior to wave action, and above which Ri≫0. Accordingly, only a small enhancement of the wind shear at… CONTINUE READING
