近几十年来，中国南方夏季洪水增加，中国北方干旱增加，中国和印度适度降温，而世界大部分地区一直在变暖。我们使用了一个全球气候模式来研究气溶胶对这些趋势的可能贡献。我们在模型中发现了降水和温度的变化，如果气溶胶中含有大比例的吸收性黑碳（“煤烟”），则与观察到的量相似。吸收性气溶胶加热空气，改变区域大气稳定性和垂直运动，影响大尺度环流和水文循环，具有显著的区域气候效应。
In recent decades, there has been a tendency toward increased summer floods in south China, increased drought in north China, and moderate cooling in China and India while most of the world has been warming. We used a global climate model to investigate possible aerosol contributions to these trends. We found precipitation and temperature changes in the model that were comparable to those observed if the aerosols included a large proportion of absorbing black carbon ("soot"), similar to observed amounts. Absorbing aerosols heat the air, alter regional atmospheric stability and vertical motions, and affect the large-scale circulation and hydrologic cycle with significant regional climate effects.
