Summary
Box models are widely used in predicting the potential hazards associated with the accidental release of heavy gas clouds, and this paper discusses whether, and how, such models should be amended to incorporate the effects of ambient wind shear. As is desirable, the proposed changes do not materially alter the simplicity of box models, which is their most important practical advantage.
