MICROSTRUCTURE OF TURBULENCE IN THE LOWER TROPOSPHERE

In this paper, the experimental data of the horizontal wind speed fluctuations at different heights from 100 to 1470 meters given by Deveatova are analysed. The main results are:1. The horizontal wind speed fluctuations at any height may be approximated by a Gaussian distribution. 2. For at a height no more than few hundred meters the well-known "2/3 law" is hold within a length scale comparable to or-several time larger than the height:3. At higher levels, the scale range in which the "2/3 law" holds good, is usually less than the height itself and no definite relationship between this scale range and the height has been found. The representativeness-of the data is also discussed.
