Abstract: A new kind of sounding is described. The relative horizontal wind between a balloon and a gondola located below it, is measured by means of high-resolution anemometers. The integration along the vertical of the relative ...

Abstract: Analysis of clear-air turbulence measurements obtained from highly sensitive balloon-borne instrumentation is presented. Emphasis is placed on the structure of the turbulent velocity field in the inertial range. Regions ...

Abstract: Analysis of the velocity filed measured by ballon-borne anemometers through a clear air turbulent patch is presented. It is shown that, except in the case where the ballon altitude is constant, the vertical wind shear ...

Abstract: Estimates of dissipation rate from remote-sensing techniques measuring the structure parameter Cn2 of density turbulent fluctuations assume a relationship between Cn2 and the dissipation rate ?. In order to obtain a precise ...

Abstract: The results of program of estimate the limiting accuracy of atmospheric wind profiles obtained by tracking a new balloon, the Rubsonde, with the Global Positioning System (GPS) are presented. In the first part, the authors ...

Abstract: Balloon-borne instrumentation for the measurement of three-dimensional air motion is described. Through the use of relative wind and static pressure, accurate wind profiles are obtained from the ground up to the stratosphere. ...
