Recent research suggests that changes in deep ocean water formation occur rather abruptly over the geological time span, leading to rapid climatic changes. This project will focus on numerical modeling of changes in the rate of deep water formation and its effect on the climate system, using energy balance models of both the atmosphere and the deep ocean. The work would enhance our understanding of rapid oscillations in the climate system that are known to have occurred over the last deglaciation episode, especially around 10,000 years ago.

最近的研究表明，深海水形成的变化在地质时间跨度内发生得相当突然，导致了快速的气候变化。该项目将重点利用大气和深海的能量平衡模式，对深水形成速率的变化及其对气候系统的影响进行数值模拟。这项工作将增强我们对气候系统快速振荡的理解，这种振荡已知发生在上一次冰期，特别是大约1万年前。
