This project has the following goals: (i) to undertake the analysis the Variability of the American Monsoon Systems (VAMOS) Ocean-Coupled-Atmosphere-Land-System (VOCALS) datasets; and (ii)to assess aerosol-cloud interactions for the southeast Atlantic and the dynamics that affect them. Precipitation impacts on aerosol indirect effects will be examined using remotely-sensed airborne VOCALS datasets and satellite-derived values. Aerosol transport pathways, their influence on and interactions with the southeast Atlantic stratocumulus deck at synoptic and diurnal time scales will also be examined, using a suite of observational datasets and reanalyses encompassing multiple years. A combination of approaches (empirical orthogonal functions, compositing, and backtrajectories and Lagrangian particle dispersion modeling) will be utilized. This project will improve understanding the dynamical influences on aerosol-cloud interactions in the Southern Hemisphere. This has the potential to improve the capability of future climate predictions; thus this activity has substantial broader impacts.

该项目具有以下目标：（i）进行分析美国季风系统（VAMOS）海洋耦合 - 大气 - 大陆 - 地区（人声）数据集的变异性； （ii）评估东南大西洋的气雾云相互作用及其影响它们的动态。将使用远程敏感的空中人声数据集和卫星衍生的值来检查对气溶胶间接影响的降水影响。还将检查气溶胶的传输途径，它们对天气和昼夜时间尺度上东南大西洋层状甲板的影响和相互作用，也将使用一套涵盖多年的观察数据集和重新分析。将利用方法（经验正交函数，合成和反射式函数以及拉格朗日粒子分散建模）的组合。该项目将改善了解南半球气溶胶云相互作用的动态影响。这有可能提高未来气候预测的能力；因此，该活动具有更广泛的影响。
