Abstract

Laboratory measurements of the autocorrelation and space-time correlations for probe separations alined with the mean flow are used to test a hypothesis of Pielke and Panofsky (1970) which relates these measures by means of an empirical decay parameter taken from coherence data. The direct laboratory measurements of the space-time correlations are in good agreement with the functions estimated using the method of Pielke and Panofsky (1970). However, the decay parameters implied for the laboratory measurements are much smaller than those reported for atmospheric turbulence.
