Abstract

The fluctuations of the horizontal and vertical wind components measured by the single head sonic anemometers at six levels in high winds were analyzed. The vertical profiles of wind speed from 10 m to 200 m can be expressed by the power law with the power of 0.3. The dependency on height of the statistical properties of turbulence such as standard deviations and friction velocity is examined. The dependency on height of the integral scale of horizontal and vertical components, and the spectral scale for both components are discussed. The vertical profiles of the gust factor (G) can be expressed by the following equation:
