| Abstract: | A two-dimensional finite-element model is developed for simulating atmospheric planturyboundary layer(PBL), and the transport and diffusion of pollutant is numerically studied. In the PBLmodel, the finite-element method provides a useful wad to studing flow phenomena that involve difference in rough length and temperatUre between land and sea, as wen as terrain and city.The outputof the PBL model is taken as the inputof a random walk method for shoulating the temporal and spatialdistribution of air polutunts during the development of sea-breeze in.coastal areas. |
