Краткое описание

In this study, we report the in-situ measurement of the strong wind velocity spectra at the northeastern coastal region of Taiwan. Strong winds were induced by the typhoon Bilis that was coming on August 21-22, 2000. The wind velocity was measured using the ultra-sonic anemometer. The wind turbulence intensity and integral length scales of the strong wind are examined. Result of the measured longitudinal wind velocity spectrum is found to be close to the wind spectrum equation of Eurocode 1. Lateral and vertical wind velocity spectra are shown to be in agreement with the isotropic turbulence spectra equations.
