Abstract

The structure of turbulence in the urban surface boundary layer is discussed. Wind and temperature fluctuations were measured with fast-response sensors at a height of 31 m at a rural and three urban sites in the St. Louis environs. The second moments of the fluctuations were computed for one-hour time series and analyzed within the framework of Monin-Obukhov similarity theory. The results are discussed relative to observed land-use features and calculated surface roughness lengths for each of the sites.
