The key drivers of past climate shifts in the Atacama Desert are still not understood. To advance our understanding of these drivers and the involved processes we will develop and use a hierarchy of models: (1) climate model results from CMIP6, (2) super-ensemble simulations including idealized global climate model runs and high-resolution simulations with WRF, and (3) a simple conceptual model for dust-aerosol burden. To better understand shifts in the dust activity, the simulations will be paired with in-situ measurements from PI-SWERL. The aim is to identify past pluvial phases and their main drivers in our model ensemble, and to analyse the response of dust-emitting winds to global atmospheric and oceanic changes.

阿塔卡马沙漠过去气候变化的主要驱动因素仍然尚不清楚。为了促进我们对这些驱动因素和所涉及过程的理解，我们将开发和使用模型的层次结构：（1）来自CMIP6，（2）超级计算模拟的气候模型结果，包括理想化的全球气候模型运行和与WRF的高分辨率模拟，以及（3）尘埃啤酒负担的简单概念模型。为了更好地了解灰尘活动的变化，模拟将与Pi-Swerl的原位测量配对。目的是在我们的模型合奏中识别过去的pluvial阶段及其主要驱动因素，并分析灰尘对全球大气和海洋变化的反应。
