Assuming two case, one was Aerosol direct radiation effect considered, two was Aerosol direct radiation effect not considered, Simulation the change of air quality and meteorological field during 2015 year by WRF/chem model, Quantitative analysis Relationship about weather-air quality-weather-air quality. The results showed: aerosol direct radiation effect led to the solar radiation reduced by 27.42W/m2, temperature reduced by 0.21℃, wind speed reduced by 1.1%, relative humidity increased by 1.4%, the boundary layer height mass concentration during 2015 year on Tianjin, meteorological conditions changed to uneasily diffusion. Due to the aerosol direct radiation effect, PM2.5 mass concentration increased by 3μg/m3, PM10mass concentration increased by 5.5μg/m3, SO2 mass concentration increased by 1.2μg/m3, but O3 mass concentration reduced by 1.4μg/m3cause by the decrease of solar radiation. Analysis that the the change of PM2.5 mass concentration about ship of weather-air quality-weather-air quality was not liner, Heavy pollution weather is significantly stronger than the cleanup day and the average condition, which leads to heavy pollution weather air quality become worse.
