摘  要:
利用WRF-chem空气质量模式对2010年四季代表月份1、4、7、10月进行情景分析,并分析北京、天津、石家庄三市API月均值与气象要素的相关性。结果表明,在气溶胶污染的影响下,2010年四季代表月份1、4、7、10月的月均太阳辐射量分别下降18.15、18.50、17.64、23.15 W/m2,月均温度分别下降0.26、0.17、0.09、0.28℃,月均大气边界层(PBL)高度分别下降15.36、21.70、15.48、29.73 m,可见气溶胶污染可造成太阳辐射量、温度、PBL高度以及风速等的降低;三市API与水汽压、平均气温和相对湿度呈负相关,与气压和平均风速呈正相关。

摘  要:
This paper investigated the effect of aerosol pollution on meteorological factors in Beijing-Tianjin-Shijiazhuang. The fully coupled online air quality model Weather Research Forecasting Model with chemistry( WRF-chem) is applied to do the simulation word and the scenario analysis methods is applied to do quantitative assessment work. The scenario analysis result of January,April,July,October in 2010 show that,monthly-average solar radiation decrease 18. 15,18. 50,17. 64,23. 15 W / m2,monthly-average temperature decrease 0. 26,0. 17,0. 09,0. 28℃,monthly-average PBL high decrease 15. 36,21. 70,15. 48,29. 73 m in January,April,July,October,which are caused by aerosol pollution. Analysis of three cities of Beijing,Tianjin,Shijiazhuang API on the correlation between the mean and meteorological elements,the results show that three API and vapor pressure and negatively correlated with the average temperature and relative humidity,and air pressure and average wind speed were positively correlated.
