Abstract : This paper analyzes Deviatova's experimental data of the horizontal wind speed fluctuations at different heights from 100 to 1470m. The main results are: (1) The horizontal wind speed fluctuations at any height may be approximated by a Gaussian distribution. (2) For heights up to a few hundred meters, the well-known '2/3' law holds within a scale of length comparable to or several times larger than the height. (3) At higher levels, the scale range in which the '2/3' law holds in usually less than the height itself and no definite relationship between this range and the height has been found. The validity of the data is also discussed. (Author)
