Abstract : In 1963 the Eighth Antarctic Expedition made observations of atmospheric turbulence at Mirnyy. About 100 radiosondes with acceleration attachments were launched. Data from 81 ascents were processed. Launchings were at 0000 and 1200 hours. Best data were obtained to altitudes 10-11 km; altitudes of 20 km were reached by 70 percent of the radiosondes, 30 km by 7-10 percent. The frequency of turbulence aloft was computed for the number of cases for each kilometer layer of the atmosphere. A particular kilometer layer was considered turbulent if it contained a turbulent layer more than 50 m thick. The frequency of turbulence relative to the tropopause and maximum wind is shown graphically in a figure. This figure shows the distribution of weak, moderate and strong turbulence relative to the tropopause. (Author)
