A wind tower with five 3-dimensional-ultrasonic anemometers observed the wind field information of typhoon Soulik 0n 15 m, 27 m, 53 m, 67 m, and 82 m respectively. The wind tower was located in Ningde, Fujian Province. In this research, the variation of gust factor and turbulence intensity over time was studied. The results show that the equation for the relationship between gust factor and turbulence intensity was fitted. Finally, the variation of the crest factor with time was studied and compared with empirical equations. It was found that under the condition of low wind speed, the crest factor at a specific time interval is greater than the research of Durst. When the wind speed is relatively high and the time interval is small, the measured value is less than the research of Durst. As the time interval increases, the measured value gradually exceeds the result.
