| Abstract: | A model is presented for determining the location and magnitude of the maximum ground-level concentration arising from an elevated buoyant source in a very stable atmospheric boundary layer. The development combines the turbulent structure of such a boundary layer, Lagrangian similarity of the diffusion process, and similarity solutions of the conservation equations of the buoyant plume with mass conservation to produce a simple, experimentally verifiable formulation. Functional analogy with previous results for the constant flux layer and a deep convectively unstable layer suggest a heuristic model by which to visualize the process. |
