Roughness Effects on Urban Turbulence Parameters
Document Type

Abstract
Urban roughness lengths are estimated from measurements of u and u* at one level under neutral conditions, assuming a logarithmic form for the vertical profile of wind velocity. At a given location in the urban area, estimated values show considerable directional variation. The dependence of some turbulence parameters on the urban roughness lengths is experimentally investigated during near-neutral conditions. The ratios Σi/u* decrease with roughness whereas the turbulence intensities Σi/u increase with it. The dependence on roughness is not the same for all components. © 1986 D. Reidel Publishing Company.
