Abstract：With the aid of measurement system which was self-developed based on Wireless Sensor Network, field measurements of wind characteristics were conducted on the roof of the National Stadium. Boundary layer wind characteristics such as mean wind speed and direction, turbulence intensity, gust factor and power spectrum density of longitudinal wind speed etc are revealed in this paper. Analysis results show that there are remarkable differences between the characteristics of the wind on the roof and the nature wind, which represent in high non-Gaussian characteristic, high turbulence, the peaks of the PSD function appeared in high frequency domain, and weak correlation among the oscillation of the different points in space; this paper proves that the theory of quasi-steady state is not applicable to the large-span roof structure .
