Aerosol-cloud interactions are one of the key factors influencing cloud properties andcirculation patterns and thereby rainfall, but also constitute the largest uncertainty in climate change forcing (Quaas et al., 2009; Boucher et al., 2013). The quantification of aerosol-cloud interactions, their radiative effects and their influence on circulation and rainfall continues to be a challenge. The present study aims to improve the scientific understanding of the influence of short-lived anthropogenic aerosols on clouds and radiation over different major emission source regions. In ACRES, I propose to (i) understand the influence of anthropogenic aerosol emission trends on regional cloud radiative effects, (ii) verify how well current climate models representthe observed regional trends in aerosol-, cloud- and rainfall quantities, (iii) understand the role of anthropogenic aerosol emission trends and consequent radiative effect trends in modulating circulation patterns, and (iv) assess whether aerosol emission trends play a role for changes in the observed extreme rainfall events over Asia.

气溶胶-云的相互作用是影响云的特性和环流模式从而影响降雨的关键因素之一，但也构成了气候变化强迫的最大不确定性（Rumas等人，2009; Boucher等人，2013年）。量化气溶胶-云的相互作用、其辐射效应及其对环流和降雨的影响仍然是一个挑战。本研究旨在提高对不同主要排放源区域的短寿命人为气溶胶对云和辐射的影响的科学认识。在ACRES中，我建议（i）理解人为气溶胶排放趋势对区域云辐射效应的影响，（ii）验证当前气候模式在气溶胶、云和降雨量方面代表观测到的区域趋势的能力，（iii）理解人为气溶胶排放趋势和随之而来的辐射效应趋势在调节环流模式中的作用，以及（iv）评估气溶胶排放趋势是否对亚洲观测到的极端降雨事件的变化起作用。
