โœฆ Synopsis

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 q/u, decrease with roughness whereas the turbulence intensities q/u increase with it. The dependence on roughness is not the same for all components.

## Abstract Data measured within and above an urban street canyon is used to analyse the importance of coherent structures in turbulent transfer. The atmosphere was probed simultaneously at six different heights from the base of the street canyon up to 2.2 times the mean building height. Integral l
