项目摘要
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.
该项目有以下目标:(一)分析美国季风系统海洋-大气-陆地耦合系统数据集的可变性;(二)评估东南大西洋气溶胶-云的相互作用以及影响它们的动力学。降水对气溶胶间接效应的影响将使用遥感机载VOCALS数据集和卫星衍生值进行检查。还将使用一套涵盖多年的观测数据集和再分析,研究气溶胶输送途径及其在天气和日时间尺度上对东南大西洋层积云甲板的影响和相互作用。将利用各种方法(经验正交函数、合成、反向轨迹和拉格朗日粒子扩散模型)的组合。该项目将增进对南半球气溶胶-云相互作用的动力学影响的理解。这有可能提高未来气候预测的能力;因此,这项活动具有广泛的影响。
