Abstract

The invention discloses a predicting method for diffusion of air pollution for complex terrain emergency response. The method comprises the steps of firstly collecting discharge data of air pollutants of parts of a zone, determining a needed discharge source list of air pollution source for calculation of a numerical model, and collecting fine terrain topographic data of the parts of the zone as the input data of a numerical model system; constructing a medium-sized weather forecast mode of the numerical model of a fine coupling boundary layer, regulating the medium-sized weather forecast mode and the numerical model of the fine coupling boundary layer so as to get an optimized simulated result of meteorological conditions, utilizing the medium-sized weather forecast mode and the numerical model of the fine coupling boundary layer as the main body to construct a predicting calculation model of air pollution diffusion, and establishing the predicting method for diffusion of air pollution for complex terrain emergency response. The predicting method for diffusion of air pollution for complex terrain emergency response can complete the predicting calculation of the diffusion range and influence degree of the air pollution for a period of 1-3 h and in an area of 10 square kilometers around an air pollution accident site within 20 minutes after the accident, is dynamically adjustable, and has a horizontal grid resolution of 100 meters and a time interval of 10 minutes.

Description

technical field [0001] The invention relates to a method for predicting air pollution diffusion in emergency response to complex terrain, and belongs to the technical field of air pollution prediction. Background technique [0002] When local air pollution occurs, quickly calculate the diffusion range of air pollution and estimate the danger range and level, which can effectively avoid accident casualties, provide decision-making basis for emergency protection work of sudden accidents, and achieve the technical support role of public safety . It can reduce casualties, losses and waste for relevant enterprises and public management departments, and indirectly improve social and economic benefits. [0003] The existing air pollution prediction and simulation methods have undergone three stages of development. The first stage was in the 1960s and 1970s, and the Gaussian diffusion model based on the assumption of a uniform flat underlying surface and turbulent steady flow was m...
