%X As the development of industry, atmosphere pollution is becoming a more important problem. This paper is written mainly for studying the plume dispersion. Because the atmosphere movement is turbulence, the mechanism of dispersion is turbulent dispersion. There are two methods to study turbulent dispersion. One is statistic theory, and the other is gradient theory. We use Lagrangian particle dispersion model (LPDM) to study plume dispersion. We calculate three factors which indicate the plume. Those are concentration on the ground along plume axis, horizontal plume width and perpendicular plume width. From the compare of calculation result with experiment data, the numerical method can simulate plume dispersion under complex climate condiction very well.
