【摘要】：利用南京大學(xué)城市空氣質(zhì)量預(yù)報(bào)模式(NJU-CAQPS)研究蘇州城市顆粒物和臭氧的相互作用,評(píng)估各效應(yīng)對(duì)污染物的影響和冬夏兩季相對(duì)重要性.研究表明冬季顆粒物的輻射效應(yīng)造成模擬域向下短波輻射減小5.4%~22%,近地面氣溫降低0.25~0.48℃,湍能和風(fēng)速減小,邊界層高度降低,城區(qū)PM2.5、NO_2、NO和SO_2濃度分別增加1.01%、0.48%、1.58%和0.71%,O_3濃度降低0.99%;顆粒物的光化學(xué)效應(yīng)造成PM2.5、硫酸鹽、硝酸鹽、O_3和NO濃度分別降低0.04%、0.07%、0.04%、4.33%和8.09%,NO_2濃度升高3.59%;顆粒物的非均相效應(yīng)造成PM2.5、硫酸鹽、硝酸鹽和NO濃度分別升高4.72%、22.07%、6.93%和2.59%,O_3、NO_2和SO_2濃度分別降低5.05%、1.19%和11.38%.非均相效應(yīng)對(duì)顆粒物、O_3和SO_2起主導(dǎo)作用;光化學(xué)效應(yīng)對(duì)NO_2和NO起主導(dǎo)作用.夏季各效應(yīng)引起污染物濃度變化趨勢與冬季相近,但夏季輻射效應(yīng)對(duì)除O_3外的NO_2、NO和SO_2影響程度加強(qiáng),對(duì)顆粒物影響程度減弱;光化學(xué)效應(yīng)對(duì)各污染物(除NO)的影響程度加強(qiáng)尤其對(duì)硝酸鹽和硫酸鹽;非均相效應(yīng)對(duì)各污染物(除硝酸鹽)的影響程度加強(qiáng).
[Abstract]:The urban air quality prediction model (NJU-CAQPS) of Nanjing University was used to study the interaction between particulate matter and ozone in Suzhou City. The effects on pollutants and the relative importance of winter and summer were evaluated. The results show that the radiation effect of particulate matter in winter results in a decrease of 5.422% in the simulated domain, a decrease of 0.25 ~ 0.48 鈩，
