摘要

Abstract >Both mean and extreme rainfall decreased over India and Northern China during 1979–2005 at a rate of 0.2%/decade. The aerosol dampening effects on rainfall has also been suggested as a main driver of mean rainfall shift in India and China. Conflicting views, however, exist on whether aerosols enhance or suppress hazardous extreme heavy rainfall. Using Coupled Model Intercomparison Project phase 5 (CMIP5) multimodel ensemble, here we show that only a subset of models realistically reproduces the late‐20th‐century trend of extreme rainfall for the three major regions in Asia: drying in India and Northern China and wetting in Southern China, all consistent with mean rainfall change. As a common feature, this subset of models includes an explicit treatment of the complex physical processes of aerosol‐cloud interaction (i.e., both cloud‐albedo and cloud‐lifetime effects), while simulation performance deteriorates in models that include only aerosol direct effect or cloud‐albedo effect. The enhanced aerosol pollution during this rapid industrialization era is the leading cause of the spatially heterogeneous extreme rainfall change by dimming surface solar radiation, cooling adjacent ocean water, and weakening moisture transport into the continental region, while GHG warming or natural variability alone cannot explain the observed changes. Our results indicate that the projected intensification of regional extreme rainfall during the early‐to‐mid 21st‐century, in response to the anticipated aerosol reduction, may be underestimated in global climate models without detailed treatment of complex aerosol‐cloud interaction. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div

Ensemble,这里我们表明,只有一个模型的子集现实地再现了亚洲三大地区的20世纪末端降雨趋势:印度和中国北部干燥和润湿在中国南方,均符合平均降雨变化。作为一个共同的特征,该模型的子集包括显式治疗气溶胶云交互的复杂物理过程(即,云-Albedo和云寿命效应),而仿真性能在仅包括气溶胶直接效果的模型中劣化云-Albedo效果。这种快速工业化时代的增强气溶胶污染是通过调光表面太阳辐射,冷却海水和水分运输疲软进入大陆区域的空间异质极端降雨变化的主要原因,而单独的温室气体变暖或自然可变性无法解释观察到的变化。我们的结果表明,在21世纪中期初期的区域极端降雨的预计加剧,以应对预期的气溶胶减少,在全球气候模型中可能低估了复杂气溶胶云相互作用的详细治疗。</
