Abstract:

The joint tower-airplane experiment was designed to provide concurrent turbulence data for one flight level at or near tower height and at the same time to supplement these data with airplane measurements above, and tower measurements below, the tower height. Three tower locations were incorporated in this experiment in an attempt to determine the effects of diffn be simply related to turbulence measured at a fixed point as a function of time, 2 Obtain data for examining low level temporal and spatial homogeneity, 3 Investigate the influence of terrain variations on the turbulence power spectral densitrent topographical conditions on the turbulence spectrum. The 4 principal objectives were 1 Obtain data to test the hypothesis of G. I. Taylor 1937 that turbulence encountered along a path in space aligned with the mean wind can be simply related to turbulence measured at a fixed point as a function of time, 2 Obtain data for examining low level temporal and spatial homogeneity, 3 Investigate the influence of terrain variations on the turbulence power spectral densities, and 4 Investigate the variation of turbulence characteristics with height above ground.
