Study on Modeling Method of Consequence Prediction System in Accidence of Dangerous Source

This study developed a prediction system for forecasting consequences of accidents based on real-time meteorological conditions. This system was established by making couple of atmospheric numerical modeling system, atmospheric dispersion model, source emission calculations module and data post-processing module. It is capable to predict concentrations of hazardous gases and harm extents in emergency. This system can provide decision makers with accurate and timely guidance, so as to minimize hazards to people and the environment.
