Abstract: Based on the actually measured wind field materials about No.10 Typhoon, namely Matmo, from high urban-landform altitude in 2014, the data were analyzed in five time intervals (30s, 1min, 5min, 10min and 20min respectively), and strong wind characteristics were obtained with respect to the averaged wind speed, the wind direction, the turbulence intensity, the gust factor, and the fluctuating wind spectrum. The turbulence integral scale was then calculated with two methods based on Taylor assumption to investigate the effects of time intervals on the turbulence integral scale regarding the averaged wind speed, the turbulence intensity, and the gust factor. The results show that the averaged wind speed is the highest when the average time interval is 5 min. However, the turbulence intensity, the wind gust factor, and the corresponding variances and coefficients of variation are the smallest. These results are reasonable due to the densest calculated distributions of turbulence integral scale and the lowest variance gained by self-correlation function integral method.
