| 摘 要： | 利用区域空气质量模式系统RAQMS,模拟研究了2010年3月东亚地区PM10气溶胶的时空演变,研究了19~23日沙尘暴暴发的过程,并将模拟结果与中国16个城市的PM10地面观测数据进行了比较.结果显示,模式对于PM10和沙尘具有好的模拟能力,可以合理地反映东亚地区PM10的时空分布和沙尘暴的演变过程;观测值和模拟值的总体相关系数达到0.705,两者平均值分别为124.8,165.5mg/m3.2010年3月份东亚地区PM10平均浓度处在较高水平,沙尘气溶胶是PM10的主要组分.3月东亚地区沙尘排放量约110.4Mt,其中68%重新沉降到地表.

| Abstract: | A regional air quality model system(RAQMS) was used to investigate the temporal and spatial variations of PM10 in East Asia during March 2010,and the dust storm broken out on 19 to 23 March.Simulation results were compared with surface PM10 observations in 16 Chinese cites.Comparison analysis showed that the model was able to reproduce the temporal and spatial distributions of PM10 as well as the evolution of the dust storm reasonably well.Correlation coefficient was 0.705 between all observational and simu... |
