| Abstract: | The standard deviations of wind velocity components are calculated and compared based on the measurements of turbulence fluctuations over three underlying surfaces: uniform, inhomogeneous and urban. Statistical analysis shows that there are the differences between them which prove the influences of surfaces roughness on turbulence. |
