Study on the short-term characteristics of the wind field in Keelung, Taiwan

Short-term characteristics of the wind field and temperature measured in Keelung, Taiwan were studied. The fluctuating components of measured wind speeds and the temperature were fitted with statistical models found in the literature. In general, the distributions of the fluctuating components are skewed, having more pronounced peaks as compared with the symmetric Gaussian model. The Edgeworthʹs type A Gram–Charlier series expansion was found to be more adequate in describing the statistical properties of the winds. Spectra of the turbulent wind fluctuations are found to follow the − 53 -power law at the high-frequency tail. The spectra of the temperature, on the other hand, are usually flat in this region, resembling that of the white noise.
