Abstract
In this paper the mean wind speed profiles in the atmospheric surfacelayer over oasis, sand, and Gobi desert surfaces in the HEIhe river FieldExperiment (HEIFE) area are discussed for various stability conditions. Themathematical representation of mean wind speed profiles obtained fromdifferent sources are used to estimate the mean wind speeds, and the resultsare compared with observed wind speed data obtained at 20 m meteorologicaltowers over different ground surfaces.
It is found that for unstable and neutral conditions, a compositeexponential profile and flux-profile relationship can be used to describe thewind speed profile in the atmospheric surface layer over homogeneoussurfaces, the composite exponential profile giving a relatively high accuracyin the estimation of wind speed profiles. For stable conditions, thecomposite exponential profile also can be used to estimate the wind speedprofile, but for very stable conditions, the accuracy is not good. For thoseconditions, flux-profile equations can give estimates of the wind speedprofile with relatively high accuracy.
