Simulation of the Impacts of Regional Transport on Air Quality of Zhengzhou, Henan
Abstract: This paper uses the nested air quality prediction modeling system (NAQPMS) to simulate a pollution case in March 2011 and estimates the contribution ratio from other different regions with a tagged method of mass trajectory. The results show that the model can well represent the pollution process and transportation of the regions. The pollut-ants transportation varies dramatically from different weather conditions. The transportation of primary pollutants and secondary pollutants is also different. During the simulation the average contribution rate of Henan to Zhengzhou PM2.5 was 82%, while the average contribution rate of SO2 and NOx were 78% and 82% respectively. In heavy pollution days, because of the influence of the southeast wind, the contribution ratio to PM2.5 from other regions could reach 53%. For SO2 and NOx, the contribution ratio was 29% and 24%.
