Super-ensemble of simulations of climate and aeolian processes in the Atacama Desert on geological time scales and their implications for life at the dry limit (A03)

阿塔卡马沙漠过去气候变化的关键驱动因素仍不清楚。为了促进我们对这些驱动因素和相关过程的理解，我们将开发和使用一系列模式：(1)来自CMIP6的气候模式结果，(2)超集合模拟，包括理想化的全球气候模式运行和使用WRF的高分辨率模拟，以及(3)尘埃-气溶胶负荷的简单概念模式。为了更好地了解尘埃活动的变化，模拟将与PI-SWERL的现场测量配对。其目的是在我们的模式集合中确定过去的雨季及其主要驱动因素，并分析扬尘风对全球大气和海洋变化的响应。

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.
