The Wind Speed Spectrum in an Industrial Environment or Does the Spectral Gap Exist?
Abstract
A wind speed energy density spectrum between frequencies of 0.0024 and 1800 cycles per hour is presented, together with other statistics of wind speed variation in an industrial environment. This spectrum has a much better resolution than any previously reported because the entire spectrum is based on a complete year's data sampled once per second. Comparison of these statistics with results given in the literature from research in open areas shows general agreement in the high frequency range (periods less than one day). The 12 and 24 hour period peaks in the spectrum are much better defined than in previously reported work and there is much less energy associated with periods greater than one day. The spectral gap does exist, but is much less pronounced than that in Van der Hoven's spectrum. (Author)
