Abstract

Wind turbulence characteristics of typhoon Megi during 27-28 September 2016 were studied with the wind data obtained from an offshore met tower near Changhua, the west coast of Taiwan. Based on the 10-min average, the results are presented with the wind speed recorded, the distribution of the probability density function, turbulence intensity, power spectrum, cross-correlation function, auto-correlation function. First, both of the power spectra of the wind data obtained at the heights 50 m and 86 m show a good agreement with the Von Karman model. Second, cross-correlation analysis of the wind data at the heights 50m and 86 m show that 85% of the time during the typhoon period the correlation coefficients were lower than 0.2, and the rest 15% of the time the correlation coefficient could reach 0.55. These observations provide important information about the wind characteristics of the boundary layer near the surface under a typhoon condition. The results are expected to be useful in the considerations in the design of offshore structures near the west coast of Taiwan.
