利用全球三维化学输运模型分析了EOS微波边缘探测仪（MLS）观测到的一氧化碳（CO）和对流层上层云。模式模拟表明，亚洲夏季风对流和地形抬升将边界层污染输送到南亚上空的对流层上层，模拟的CO分布与MLS观测结果相似。模式结果还显示反气旋区域的气溶胶升高。这些气溶胶可能是一些密集高空云形成的原因。
A global 3‐D chemical transport model is used to analyze observations of carbon monoxide (CO) and upper tropospheric clouds from the EOS Microwave Limb Sounder (MLS). MLS observations during 25 August–6 September 2004 reveal elevated CO and dense high clouds in the upper troposphere over the Tibetan plateau and southwest China, collocating with the upper level Tibetan anticyclone. Model simulations indicate the transport of boundary layer pollution by Asian summer monsoon (ASM) convection and orographic lifting to the upper troposphere over South Asia, where simulated distributions of CO resemble MLS observations. Model results also show elevated aerosols in the anticyclone region. Analysis of model simulated CO and aerosols indicate that the Tibetan anticyclone could ‘trap’ anthropogenic emissions lifted from northeast India and southwest China. These aerosols may be responsible for the formation of some of the dense high clouds.
