摘要
文章介绍了一种利用单一高度风速、温度湍流资料确定空气动力学参数的方法．该方法无须进行风速廓线的测量，可以应用于非单一水平均匀下垫面和非中性层结，避免了主观性．用该方法计算了北京城市北部边缘３２５ｍ气象塔附近的零值位移ｄ和地表粗糙度ｚ０．结果表明：该处下垫面零值位移ｄ和地表粗糙度ｚ０与风向有很强的依赖关系，与气象塔周围的城市建设相对应．
The method to estimate aerodynamic parameters with only velocity and temperature fluctuation data is applied to non homogeneous surfaces and non neutral stratification. The turbulence data measured in Beijing Meteorological Tower which is 325 m high are used to determine the zero plane displacement d and surface roughness z 0. It is shown that the d and z 0 are considerable dependent on wind direction.
