Abstract:Based on the numerical weather prediction model and automatic weather station data, random-walk particle-puff model was used to simulate the emergency response to atmospheric accident. The model for atmospheric diffusion could simulate the atmospheric diffusion in case of emergency accident occurred in 10min, both distribution of the particle and concentration calculated by the model could describe the variation of the diffusion route and affected area. Random walk model, as atmospheric diffusion module of the emergency accident decision support system, could provide more actual information for early emergency and consequence assessment.
