Abstract
An engineering boundary layer wind model based on data collected at the NASA 150-meter meteorological tower facility at the Kennedy Space Center in Florida is discussed. A statistical power law peak wind profile is used to extrapolate peak wind statistics valed at the 10-meter to other levels. The relationship between the instantaneous extreme wind profile and the peak wind profile for various periods of exposure up to 10 minutes is examined. The gust factor profile, which depends on the peak wind speed, height and averaging time, is applied to the peak wind profile to obtain a mean wind profile. A spectral model of the longitudinal and lateral components of turbulence for the neutral boundary layer (high wind speeds) is presented.
