Abstract : Special aircraft sounding with an IL-28 near Khabarevak has provided data on the frequency and structure of turbulent zones at heights of 6-12 km and their relationship to upper level clouds, atmospheric thermodynamic processes, the tropopause, jet streams and the pressure field. The apparatus used, schematically shown in the Enclosure, is described briefly. During vertical sounding at the indicated heights 49% of all flights were without turbulence, 35% were with slight turbulence, 15% with moderate turbulence and 3% with moderate to strong turbulence. During horizontal sounding no turbulence was observed 56% of the time slight turbulence 37% of the time and moderate turbulence 7% of the time. (Author)
