本文着重分析了城市冠层（UCL）内外的交换过程及其形态学参数的描述。以前的工作已经表明，潜在的形态学方法的平均流量和分散在城市冠层的建模。在这项研究中，我们认为从当地建筑物的功能，以评估以前的模型在冠层和交换速度的流量特性的依赖。我们使用四个超声波风速计位于一个大的工业现场的一个城市在意大利中部和详细的建筑物数据的流量和湍流测量。这个网站已被选为一个例子，孤立的社区的一个真实的城市，适合于测试以前的模型，从实验室实验中得出的冠层和交换速度。
This work focuses on the analysis of exchange processes in-out an urban-like canopy layer (UCL) and their description in terms of morphometric parameters. Previous work has shown the potential of morphometric methods for the modelling of the mean flow and dispersion within the urban canopy layer. In this study we consider the dependence of flow characteristics from local building features in order to evaluate previous models for the in-canopy and exchange velocities. We use flow and turbulence measurements from four ultrasonic anemometers located in a large industrial site of a city in central Italy and detailed building data. This site has been chosen as an example of isolated neighborhoods of a real city, suitable for testing previous models for the in-canopy and exchange velocity derived from laboratory experiments.
