The power spectrum of relatively short wavelength turbulence in the atmosphere was calculated from measurements made in flight. The range of wavelengths covered by these measurements was from 10 feet to 200 feet. The power spectral density varies with the square of the wavelength of the turbulence. This variation is in general agreement with the high-frequency asymptote of the spectrum form generally assumed for isotropic turbulence. Flow-direction vanes were used to measure the vertical and horizontal components of gust velocity normal to the flight direction. The power spectral densities of the two components are, for practical purposes, equal. The use of vanes is shown to afford a simple, direct method of obtaining the power spectral density of atmospheric turbulence in the relatively high frequency range of airplane response.
