摘要：

A method to estimate the zero plane displacement is presented that is based on in situ turbulence measurements. As it does not depend on flux-gradient relations, it can be applied over non-homogeneous surfaces if they are dynamically but not thermally distorted. The zero plane displacement at an urban site is found to vary considerably with wind direction. The results compare well with estimates from conventional methods using the heights and distribution of the upwind roughness elements.
