摘要：
A dispersion model incorporating a large wind direction shear has been developed for an industrialized coastal area with an indented coastline and rough terrain. The model is based on a first-order closure solution for the vertical spread and a Gaussian profile for the lateral spread. Lateral spread is obtained by numerical integration of turbulent energy spectra. The model is verified against a large number of tracer experimemts with near surface release within industrial complexes. The model is shown to correctly simulate shear-enhanced spread out to a distance of 10 km from the source. Part of the observed scatter is believed to be the result of an oversimplified plume rise calculation.
