讲座简介：

    As the community strives to understand regional climate change at various spatiotemporal scales,    anthropogenic aerosols and greenhouse gases are expected to feature prominently. Despite a few early attempts, their impacts on the general circulation and hydrological cycle have not been examined in a systematic manner. In this talk, I will describe a top-down approach to the issue, starting from global-means first before moving to zonal-means, and then to zonal asymmetries within a latitude band. A wide range of seemingly different problems (e.g., transient climate response, aerosol absorption, Hadley circulation, tropical stability and monsoon) will be discussed. Yet, with the help of observations, theories and numerical models, I will show that the solutions all fit into one overarching framework.
