In this report, the scale of turbulence was discussed along the line of the statistical theory of turbulence of G. I. Taylor. Time correlation Rξ were calculated and forms of (Rξ-ξ) curves were shown. Spacial correlation _??_z were also calculated. Scale fo turbulence Rξ dξ is about 30 meters in the cases of strong wind and is about 3 meters in the cases of slow wind at a height of 60 meters. From the curves of Rξ, the spectral distributio of the turbulent energy were calculated according to the theory of G. I. Taylor. Brief discussions were done on the menthod of statistical analysis of the record of velocity fluctuations.
