A Reentry Plume Fumigation Model in a Lakeshore Environment
In a lakeshore environment, the airflow continuously readjusts itself to underlying surface characteristics as it crosses the surface discontinuity between land and water. The sudden change in surface roughness and temperature can result in significant modifications to the wind flow field and its mechanical and thermal turbulence levels and consequently, can affect the dispersive capabilities of the atmosphere. During persistent stable onshore gradient flow conditions, a thermal internal boundary layer (TIBL) will be developed over land. This layer typically starts at the shore and increases in height as a function of inland distance. For a tall stack situated near the shore, fumigation and trapping of the plume within the TIBL are likely to result in very high ground-level pollutant concentrations.
