Abstract

Our experience in applying earlier versions of a model of boundary-layer flow over low hills to real terrain (see Walmsley et al., 1982) has led to the development of a new version which we designate MS3DJH/3. The main improvements are the use of terrain-dependent length and velocity scales and the blending of inner and outer layer results into a single ‘universally valid’ solution for the velocity perturbation field. MS3DJH/3 was carefully calibrated against alternative computations of flow over idealized two-dimensional terrain features using more detailed models prior to its application to real, three-dimensional terrain. It still provides high spatial resolution with low computing cost and is applicable to flow over terrain features with horizontal scales from 10 m to 10 km.
