| 摘 要： | 本文利用全球三维大气化学模式MOZART-2，采用两组不同的污染源数据对东亚地区对流层臭氧（O3）及一氧化碳（CO）浓度的季节变化进行了模拟。通过与观测资料进行对比发现，模拟结果能较好的再现日本南鸟岛站与绫里崎站观测到的季节变化特征。由于这两观测站所处的环流场形势不同，受亚洲大陆污染物出流的影响程度有所差别，两组排放源下CO与O3浓度的模拟差异在两地的表现有所不同，在绫里崎站可以看到CO与O3浓度的模拟差异呈现出比较显著的季节性特征。 |

| Abstract: | The transport and photochemical transformation of tropospheric ozone and carbon monoxide in East Asia was studied by using a three-dimensional global atmospheric chemistry transport model MOZART-2 with two different emission scenarios. The simulated mixing ratios of ozone and carbon monoxide are compared with ground level observations at Minamitorishima and Ryori in Japan and it is found that the model reproduces the observed features reasonably well. Minamitorishima, located about 2000 km southeast of Tokyo, is surrounded by ocean, while Ryori is located north of 30ºN, belonging to the East Asia monsoon area and being greatly affected by continental outflow. Due to differences in geographical locations and meteorological factors as mentioned above, the changes in emissions significantly influence the mixing ratios of ozone and carbon monoxide over Ryori. |
