We developed an elaborated direct measurement system for drag force acting on a buildings block area. By using this device, systematic and comprehensive wind tunnel experiments to identify the so-called Bulk Drag (Momentum) Transferring Coefficients for various cases targeted at realistic urban situations represented by several complex geometric parameters. We also developed a measurement system for accurate evaporation rate from water surface based on the so-called Salinity Method. By means of this, we conducted another series of wind tunnel experiments to obtain the so-called Drag Scalar Transferring Coefficients. Those two series of experiments are designed to be comparable in terms of having same geometric parameters. Huge amount of the experimental data sets leads to clarify what geometric parameter dominates on both momentum and scalar transfer within/ just above urban canopy. To the end, turbulent transferring effects for both momentum and scalar are enforced by "randomness" resulting from building height distribution, roughness array.

研制了一套复杂的建筑物块体阻力直接测量系统。通过使用该装置，系统和全面的风洞实验，以确定所谓的体积阻力（动量）传递系数的各种情况下，针对现实的城市情况下，由几个复杂的几何参数表示。我们还开发了一个测量系统，从水面蒸发率的基础上所谓的盐度法。通过这种方法，我们进行了另一系列的风洞实验，以获得所谓的阻力标量传递系数。这两个系列的实验被设计为在具有相同几何参数方面具有可比性。大量的实验数据集导致澄清几何参数主导的动量和标量传输内/上方的城市冠层。最后，由于建筑物高度分布、粗糙度排列等因素的“随机性”，使得动量和标量的湍流传递效应得到加强。
