Popis: Complicated terrain and atmospheric stability are important factors in the prediction of gas diffusion in the atmosphere where a stack is located near a shoreline. In coastal onshore air flows, a thermal internal boundary layer (TIBL) often develops as a result of abrupt change in temperature between cool sea surface and warm land surface. In TIBL, turbulent properties are considerably different from those of in stable or neutral boundary layers, and these differences have a significant influence on dispersion of air pollutants in coastal area, and causes fumigation phenomenon which brings high ground level concentration (GLC) as shown in Fig. 1.
