Late Cenozoic Plateau Uplift and Climate Change

这项拟议中的研究将测试新的假设，即高原 隆升是晚新生代气候变化的根本原因。 具体来说，这项工作将涉及敏感性测试实验 两个大气环流模式（GCM）以及分析 晚新生代趋势的核心DSP和ODP序列监测 风吹尘通量和表层海洋生产力 赤道大西洋、东大西洋和西北太平洋。 这项研究的结果应该解决几个关键问题 关于晚新生代，包括相对影响 地形和CO2变化对区域和全球变冷的影响 水分平衡模式的变化。

The proposed research will test the new hypothesis that plateau uplift is a fundamental cause of late-Cenozoic climate change. Specifically, this work will involve sensitivity-test experiments with two general circulation models (GCM's) as well as the analysis of late-Cenozoic trends in cored DSP and ODP sequences to monitor windblown dust fluxes and surface-ocean productivity in the equatorial Atlantic, eastern Atlantic and northwest Pacific oceans. The results of this study should address several key questions about the late-Cenozoic, including the relative influence of orographic and CO2 changes to regional and global cooling as well as to changes in moisture-balance patterns.
