第二十五届大气污染防治技术研讨会

作者： Shanshan Ouyang Tao Deng Shaw Chen Liu Run Liu Institute for Environmental and Climate Research Jinan University Guangzhou Institute of Tropical and Marine Meteorology China Meteorological Administration

Severe ozone pollution events are often related to weather systems. For the Pearl River Delta(PRD),the main weather conditions affecting ozone pollution are subtropical high and tropical cyclone. A persistent ozone pollution event occurred over PRD during 25 th September to 1 st October 2019,in which the average daily ozone concentrations in nine cities of the PRD exceeded 160 μg/m. By means of the observational analysis and the numerical simulation,the effects of subtropical high and tropical cyclone on ozone pollution in the PRD were investigated in this study. The observational analysis shows that under the control of subtropical high,the weather conditions such as high temperature,low relative humidity and low wind speed play an important role in the formation and accumulation of ozone in the PRD. In addition,tropical cyclone Myra formed on 28 September and developed rapidly,which caused the PRD affected by the periphery circulation of typhoon,resulting in a worse air quality. WRF-CMAQ model was used for numerical simulation of the pollution period,and combined with the integrated process rate(IPR) analysis for further illustrate. The results show that the vertical diffusion(VDIF) and the gas-phase chemistry(CHEM) are the main factors to the ozone formation in the PRD. In order to quantify the contribution of tropical cyclones to the ozone pollution event in the PRD;the bogus method was used to remove the tropical cyclone circulation in the background field to compare the difference of ozone concentration between the typhoon and the de-typhoon conditions.

Quantification of the nonlinearities between ambient ozone(O3)and the emissions of nitrogen oxides(NOx)and volatile organic compound(VOC)is a prerequisite for an effective O3 control *** Enhanced polynomial functions Response Surface Model(Epf-RSM)with the capability to analyze O3-NOx-VOC sensitivities in real time was developed by integrating the hill-climbing adaptive method into the optimized Extended Response Surface Model(ERSM)*** Epf-RSM could single out the best suited polynomial function for each grid cell to quantify the responses of O3 concentrations to precursor emission *** comparisons between Epf-RSM and pf-ERSM(polynomial functions based ERSM)were performed using out-of-sample validation,together with comparisons of the spatial distribution and the Empirical Kinetic Modeling Approach *** comparison results showed that Epf-RSM effectively addressed the drawbacks of pf-ERSM with respect to overfitting in the margin areas and high biases in the transition *** O3 concentrations predicted by Epf-RSM agreed well with Community Multi-scale Air Quality simulation *** case study results in the Pearl River Delta and the north-western area of the Shandong province indicated that the O3 formations in the central areas of both the regions were more sensitive to anthropogenic VOC in January,April,and October,while more NOx-sensitive in July.
