In the past two decades, inhabitants of Ulaanbaatar city have been increased more than three times. The Air and soil of Ulaanbaatar city contaminated seriously due to the densely populated behavior. We proposed to develop a massive computational model for pollution, which cares about contamination factors. This paper is a part of the purpose. We consider the filtered equation express conservation of mass and momentum in a Newtonian incompressible flow in a computational fluid dynamic model for Ulaanbaatar’s wind field. The terrain around the city has been built for numerical computation. The finite element method was used for numerical analysis, from the results, we can characterize the wind field.
