We report on the structure of atmospheric turbulence especially focusing on the spatial correlations of three fluctuating components of wind speed using our records measured at a transmission tower located at the tip of a cape. According to our results, the profiles of the longitudinal and lateral wind speeds due to typhoons were different from those due to non typhoons. And we showed that cross-correlations between the longitudinal and vertical lateral components of the fluctuating wind speeds were explained by the theoretical expressions in the isotropic turbulence theory, using the correlation coefficients of the longitudinal and vertical lateral components normalized by the longitudinal scale of turbulence of the longitudinal wind speed.
