Abstract

In order to get more accurate air pollution distribution effected by complex terrain such as hilly or mountain areas two models, one is PBL model other is random walk transportation model (Monte Carlo), are developed to simulate air pollutant's concentration distribution. The PBL model is a fine-mesh, higher resolution, three-dimension non-hydrostatic model; higher order turbulence closure scheme is adapted. A wind tunnel experiment for verifying the model's ability is showed that the results of the model accord with the wind tunnel experiment. The outputs of PBL model are inputs of random walk model as the initial meteorological conditions. The case study of modeling a power station air pollution in hilly area in Henan, China expressed in this paper also shows that complex terrain can significantly increase pollution concentration at ground level.
