Abstract : In the past 10-15 years, Soviet meteorologists have carried out considerable research on atmospheric turbulence and the role of turbulent exchange in cloud-forming processes. Many of the most recent studies have involved observations of aircraft buffeting (bumps) measured at high altitudes with airborne accelographs which recorded turbulence only at certain levels of sensitivity (usually only severe bumps). In addition, the aircraft frequently were deliberately flown over routes along which there was a high there was a high probability that severe turbulence would be encountered, and the equipment used rarely permitted determination of coefficients of turbulent exchange under 10 m2/sec. On the assumption that such observations were not representative, particularly in the surface boundary layer of the atmosphere, the Central Aerological Observatory in the 1962-1963 period made a series of low-level flights in a specially equipped LI-2 plane. All of the main atmospheric elements were measured; aircraft buffeting was registered with an MP-23 potentiometric sensor. (Author)
