项目摘要
The aim of the project is to compare the Holocene and Eemian atmospheric hydrological cycle by combining paleo proxy reconstructions with climate model simulations. As the Eemian climate was probably by 1 to 2°C warmer than that of the Holocene, an intensified hydrological cycle can be expected. However, paleo proxy data do not clearly indicate such wetter conditions, whereas climate model results support more intense monsoon systems under warmer Eemian climate. In the proposed study existing and new paleorecords of monsoonal precipitation stemming from marine sediments off Africa, India, and China will be compiled into a comprehensive data set together with existing proxy records from terrestrial archives. Climate model simulations using a state-of-theart coupled atmosphere ocean general circulation model (AOGCM) will be used for comparison with the paleodata records and for the analysis of spatial as well as temporal variability patterns in the atmospheric hydrological cycle. We will focus on three key regions (Gulf of Guinea, Bay of Bengal and South China Sea), where marine paleodata allow insights into the continental paleohydrology by isotope studies on land plant lipid material and for river runoff via salinity variations. Furthermore we aim, with the help of the climate model, to better separate and statistically analyse marine and terrestrial hydrological effects at the respective core locations and in the catchment areas of the respective rivers.
该项目的目的是通过将古代用资料重建与气候模型模拟相结合,比较全新世和Eemian大气水文循环。由于Eemian气候可能比全新世高1至2°C,因此可以预期水文循环会加剧。然而,古代用资料并没有清楚地表明这种潮湿的条件下,而气候模式的结果支持更强烈的季风系统下温暖的Eemian气候。在拟议的研究中,来自非洲、印度和中国海洋沉积物的季风降水的现有和新的古记录将与来自陆地档案的现有代用记录一起汇编成一个综合数据集。将使用最先进的大气-海洋环流耦合模式进行气候模式模拟,与古数据记录进行比较,并分析大气水文循环的空间和时间变异模式。我们将专注于三个关键地区(几内亚湾,孟加拉湾和中国南海),海洋古数据允许通过对陆地植物脂质材料的同位素研究和通过盐度变化的河流径流深入了解大陆古水文。此外,我们的目标是,在气候模型的帮助下,更好地分离和统计分析海洋和陆地水文影响在各自的核心位置和各自的河流的集水区。
