This collaborative project seeks to understand the role of the tropical Pacific climate in the dynamics of glacial-interglacial cycles. Observationally, the tropics show significant climate fluctuations related to these cycles, and the dynamical understanding demands that they play a role in global climate change. The PIs will undertake a numerical modeling study using a coupled model designed for the tropical ocean-atmosphere that will address two broad questions: 1) how does the tropical Pacific climate respond to glacial climate forcings, and 2) what is the resulting impact of these changes on glacial climate? This work will enhance understanding of tropical dynamics as a critical factor in understanding regional climate under changing boundary conditions. Funding will support a PhD student at UC Berkeley.

该合作项目旨在了解热带太平洋气候在冰川-间冰期循环动力学中的作用。从观测上看，热带地区表现出与这些周期相关的显著气候波动，动力学的理解要求它们在全球气候变化中发挥作用。研究人员将使用为热带海洋-大气设计的耦合模型进行数值模拟研究，该研究将解决两个广泛的问题：1）热带太平洋气候如何对冰川气候强迫作出反应，以及2）这些变化对冰川气候的影响是什么？这项工作将加强对热带动力学的理解，将其作为了解边界条件变化下区域气候的一个关键因素。资金将支持加州大学伯克利分校的一名博士生。
