气象条件模拟与污染扩散数值变化的影响建模研究

Modeling and Analysis of Impact of Simulation of Meteorological Conditions and Numerical Variation of Pollution Diffusion

传统的气象条件模拟与污染扩散数值变化的影响分析模型分析误差较大,为此设计一种气象条件模拟与污染扩散数值变化的影响分析模型。模拟气象条件,确定污染物扩散影响参数,计算风与湍流对污染扩散的影响,并从平流输送过程、扩散过程、气相化学过程、气溶胶过程、排放过程、云混合与液相化学反应和干沉降过程7方面对污染扩散数值变化模拟,以此完成气象条件模拟与污染扩散数值变化计算。

The analysis error of traditional meteorological conditions simulation and the impact analysis model of numerical variation of pollution diffusion is relatively large.An influence analysis model of the simulation of meteorological conditions and numerical variation of pollution diffusion is designed.The study simulates meteorological conditions,determines the influence parameters of pollutant diffusion,calculates the effects of wind and turbulence on pollution diffusion,and determines the effects of advection,diffusion,gas phase chemical processes,aerosol processes,emission processes,cloud mixing and liquid phase chemical reactions.The seven aspects of the settlement process simulate the numerical change of pollution diffusion,so as to complete the simulation of meteorological conditions and the calculation of numerical change of pollution diffusion.
