Whiteway, J.A., Pavelin, E.G., Busen, R., Hacker, J. and Vosper, S. (2003). Airborne measurements of gravity wave breaking at the tropopause. Geophysical Research Letters 30: doi: 10.1029/2003GL018207. issn: 0094-8276.

A breaking atmospheric gravity wave was investigated with a combination of airborne in-situ dynamical measurements and ground-based VHF radar observations. The wave was generated by flow over mountains and it was observed to break near the tropopause. The measurements reveal that the wave was overturning at the tropopause and that the initial breakdown into turbulence involved the generation of smaller oscillations with a horizontal wavelength of around 500 m. There was also evidence that the turbulence associated with the wave breaking can cause substantial mixing in the tropopause region.
