Recent years have seen the development, by a number of workers, of models describing airflow over real topography. Within the Boundary-layer Research branch of the Meteorological Office, a two-dimensional, incompressible, non-hydrostatic model of flow over complex terrain has recently been tested against measurements of mean wind and turbulence, in neutral stability, in a system of nearly two-dimensional valleys (Mason and King, 1984).
