title: Simultaneous measurements of clear air turbulence at the tropopause by high-power radar and instrumented aircraft.
abstract: Large amplitude Kelvin-Helmholtz billows observed by radar at a height of almost 11 km are shown to have been associated with clear air turbulence which produced a vertical aircraft acceleration of 0.65g.
