本文讨论了城市地面边界层的湍流结构。风和温度的波动进行了测量与快速响应传感器在31米的高度在农村和三个城市的网站在圣路易斯郊区。波动的二阶矩计算一个小时的时间序列，并在莫宁-奥布霍夫相似性理论的框架内进行分析。相对于观察到的土地利用特征和计算的表面粗糙度长度的网站的结果进行了讨论。
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.
