项目摘要

This supports analysis of collected during the Variability of the American Monsoon Systems Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx, or simply REx). The VOCALS-REx field campaign took place over the Southeast Pacific Ocean (SEP) during Oct-Nov 2008, and was designed to improve understanding of interactions between aerosols, marine boundary layer (MBL) clouds, and precipitation over the region. The SEP is climatically important because it is home to the world's largest subtropical stratocumulus cloud deck, which cools the climate by reflecting solar radiation back to space. Thus interactions between clouds, aerosols, and precipitation in the SEP can have an important climatic effect by modulating cloud cover and cloud albedo. The research here continues two key REx themes: research on Pockets of Open Cells (POCs), which are openings in the stratocumulus deck in which clouds have presumably dissipated due to drizzle formation; and research on offshore transport of pollution and its effect on SEP cloud and aerosol characteristics. Observations of cloud droplet concentration taken during REx using the NCAR C-130 aircraft show large "hook" features extending offshore from the Chilean coast, which may be due to high concentrations of cloud condensation nuclei (CCN) associated with pollution from copper smelters and coastal conurbations.Research performed under this grant uses REx data, much of which has not been previously analyzed, as well as data from global atmospheric model simulations prepared for the VOCALS Model Assessment (VOCA), together with numerical experiments using a large-eddy simulation (LES) code, to develop a better understanding of POCs, hooks, and SEP aerosol-cloud interactions. Three broad science questions are addressed: 1) How important is the free-tropospheric aerosol source to CCN and cloud droplet number concentrations in the VOCALS region, especially in the oceanic region over 500 km away from coastal pollution sources? 2) Is the precipitation sink for aerosols a major positive feedback on CCN differences between clean and polluted regions, in particular for hooks and POCs? 3) Can regional and global chemistry-climate models that include some representation of aerosol-cloud- precipitation interactions realistically simulate hooks and POCs?Beyond its scientific merit, the project has broader impacts due to the important role of SEP clouds in regulating earth's climate. A better understanding of the role of aerosol-cloud interactions in determining cloud cover and cloud brightness could thus lead to improved understanding and predictions of climate variability and change. In addition, the project supports two graduate students, thereby providing for the next generation of the scientific workforce in this area.
这支持了对美国季风系统海洋-云-大气-陆地研究区域实验(VOCALS-REx,或简称雷克斯)变率期间收集的数据的分析。VOCALS-REx现场活动于2008年10月至11月在东南太平洋(SEP)上空进行,旨在提高对该地区气溶胶、海洋边界层(MBL)云和降水之间相互作用的理解。SEP在气候上很重要,因为它是世界上最大的亚热带层积云的所在地,通过将太阳辐射反射回太空来冷却气候。因此,云,气溶胶和降水之间的相互作用,在SEP可以通过调制云量和云量有一个重要的气候效应。这里的研究继续两个关键的雷克斯主题:研究口袋的开放单元(POC),这是在层积云甲板上的云可能已经消散,由于毛毛雨形成的开口;和污染的离岸运输及其对SEP云和气溶胶特性的影响的研究。 在雷克斯期间使用NCAR C-130飞机进行的云滴浓度观测显示,从智利海岸延伸到近海的大“钩”特征,这可能是由于与铜冶炼厂和沿海城市群污染相关的高浓度云凝结核(CCN)。在该资助下进行的研究使用了雷克斯数据,其中大部分以前没有分析过,以及为VOCALS模式评估(VOCA)准备的全球大气模式模拟的数据,以及使用大涡模拟(LES)代码的数值试验,以更好地了解POC,hook和SEP气溶胶-云相互作用。 讨论了三个广泛的科学问题:1)在VOCALS区域,特别是在距离沿海污染源500 km以上的海洋区域,对流层气溶胶源对云凝结核和云滴数浓度的重要性有多大?2)气溶胶的降水汇是清洁和污染地区之间的云凝结核差异的一个主要的正反馈,特别是钩和POC?3)区域和全球化学气候模式,包括一些代表性的气溶胶-云-降水相互作用,能够真实地模拟钩和POC?除了其科学价值外,由于SEP云在调节地球气候方面的重要作用,该项目具有更广泛的影响。 因此,更好地了解气溶胶-云相互作用在确定云量和云亮度方面的作用,可以改善对气候变异性和变化的了解和预测。 此外,该项目还资助两名研究生,从而为该领域的下一代科学工作者提供支持。
