Abstract: Simultaneous measurements of turbulent vertical velocity fluctuations at a height of 300 ft. measured by means of a fixed anemometer, small floating balloons, and airplane gust equipment at Brookhaven are presented. The ...

Abstract: Under the assumption of homogeneous and isotropic turbulence, an equation is obtained for diffusion from an instantaneous volume source that has spherical symmetry but otherwise a virtually arbitrary initial distribution. ...

Abstract: Approximately 2,000 zero-lift, double-theodolite pilot balloon observations made at Oak Ridge, Tenn., are analyzed in order to study low level air trajectories over hilly terrain. Paths of air parcels are found to fall ...

Abstract: Previously, analysis of the Eulerian time correlation has been restricted to the limiting cases of very small turbulence level (G. I. Taylor's hypothesis) and very large turbulence level. In the atmosphere, the turbulence ...

Abstract: The spreading of smoke puffs in the atmosphere should be governed by the laws of relative diffusion that have been advanced by Brier and by Batchelor, and not (contrary to what has been previously assumed) by Taylor's ...
