| 摘 要： | 2001-03-21在昆明用电化学臭氧探空仪探测到了对流层低层异常的高浓度臭氧分布。这个个例中昆明对流层低层异常的高浓度臭氧分布特征不同于2001-03-08的昆明个例。使用NCEP分析资料、中尺度数值模式MM5模拟的大气环流数据、卫星观测的东南亚地区的生物体燃烧状况、气溶胶指数等资料,分析了这段时间的天气形势、大气环流、空气块后向轨迹以及生物体燃烧产生的烟尘轨迹,结果发现高浓度的臭氧空气来源于有生物体燃烧的南亚地区。这与以往研究中东南亚地区生物体燃烧导致华南地区对流层低层臭氧浓度异常增高有所不同。

| Abstract: | Ozone enhancement was observed in the lower troposphere over Kunming on 21 March 2001 using electrochemical concentration cell ozonesondes. The influence of the biomass burning in South Asia on ozone concentration in the lower troposphere over Kunming is analyzed, based on NCEP reanalysis, Total Column Ozone, numerical simulation of MMS, AI from TOMS, and aerosol optical depths from MODIS. It is shown that the enhancement of ozone in the lower troposphere over Kunming is due to biomass burning emissions in South Asia. TOMS AI images and the atmospheric background circulations suggest that biomass burning plumes in South Asia are transported to Kunming and cause the enhancement of ozone concentrations in the lower troposphere. |
