Abstract : An approximate formula is derived for the relationship between wind-speed fluctuation correlation, the standard deviation, and the respective components of the wind-speed fluctuation for small gustiness. The calculation indicates that for the gustiness ordinarily encountered in investigation of the microstructure of atmospheric turbulence, the correlations of the standard quantities and the eddy components do not differ greatly. It is shown that the spatial correlation of the wind speed fluctuation can, in approximation, be replaced by the time correlation if the atmospheric turbulence is of small magnitude. The validity of the additional assumptions made regarding the atmosphere in the derivation of the formula is also discussed. (Author)
