气溶胶对地球系统的影响不容忽视。气溶胶浓度的变化直接或间接地改变了云的光学性质和寿命，从而对气候产生了各种影响。除了辐射收支的变化外，气溶胶还具有改变云和降水的巨大潜力。东亚是世界上气溶胶浓度最高的地区。这项工作旨在利用卫星数据和GCM模拟来调查东亚地区的气溶胶分布，并估计气溶胶对区域气候变化的影响。气溶胶对东亚地区气候的影响大于全球平均水平。模拟结果表明，地面降温和气溶胶效应减弱了季风环流。
Aerosol impacts on Earth's system are not negligible. The change of concentration of aerosols causes various effects on the climate by directly and indirectly modifying the optical properties and lifetimes of cloud. In addition to radiation budget change, aerosol has a significant potential to change cloud and precipitation. East Asia is the area with high concentration of aerosols in the world. This work intends to investigate distribution of aerosols over East Asia and estimate impacts of aerosol on regional climate change using by satellite data and GCM simulations. Aerosol impacts on climate over East Asia is larger than global mean. The simulated results show that surface cooling and weaken monsoon circulation by aerosol effects.
