项目摘要

This research program seeks to understand phenomenology involving the coupled evolution of the solid Earth, the oceans, the atmosphere and continental ice sheets and sea ice. A unique contribution of this program involves the gravitationally self-consistent theory of Ice-Earth-Ocean interactions and relative sea level history. An important component of the proposed work will involve refinement of the ice sheet loading history of the continents during the most recent Late Quaternary ice-age cycle. The proposed work will also focus upon the explanation of why such glacial cycles are characterized by a distinctly "sawtooth" form in which the glaciation phase of the cycle is much slower and lasts longer than the deglaciation phase, a feature which appears to be controlled by extremely fast ice stream related instabilities that control the deglaciation phase. This aspect of the program has delivered the models of glaciation history that continue to be employed ubiquitously by the international community to provide the boundary conditions needed to support global climate model-based reconstructions of past climate conditions. Aside from continuing work on high resolution regional climate modeling of both modern and past climate states, a unique contribution of the Toronto group will continue to be work to more fully understand the so-called Dansgaard-Oeschger oscillation phenomenon that dominated climate variability during Marine Isotope Stage 3. As the Peltier group has shown these oscillations are triggered by the fast ice stream instabilities called Heinrich events for which a new theory has also been proposed that will be more fully explored in this proposed program of study. A primary focus of new research in this area will be on understanding the dependence of this D-O phenomenon upon the orbital insolation regime and other characteristics of the successful simulations that have already been produced. These D-O results have been shown to rely significantly upon the manner in which small scale ocean turbulence processes are parameterized in the global ocean component of the UofT climate model, especially the representation of ocean diapycnal diffusivity. A major contribution of the Toronto program continues to involve the development of theory and numerical simulation-based results that are leading to significant improvements in the representation of such small scale processes in low resolution ocean models. A particular focus in the next grant period will be upon the extent to which internal wave breaking may be contributing to ocean diapycnal diffusivity. This work is being supported by extremely high resolution MITgcm-based simulations with models explicitly forced by the astronomical tides and atmosphere derived surface forcing. This focus upon ocean turbulence processes based upon formal fluid mechanical analyses is the last of the linked set of investigations that will comprise the work to be undertaken in the next grant period.
该研究计划旨在了解涉及固体地球,海洋,大气和大陆冰盖和海冰的耦合演化的现象学。该计划的一个独特贡献涉及冰-地球-海洋相互作用和相对海平面历史的重力自洽理论。拟议工作的一个重要组成部分将涉及在最近的晚第四纪冰期周期的大陆冰盖加载历史的细化。拟议的工作还将侧重于解释为什么这样的冰川循环的特点是一个明显的“冰”的形式,其中循环的冰川阶段是慢得多,持续时间比冰川消退阶段,这似乎是由控制冰川消退阶段的极快的冰流相关的不稳定性控制的功能。该计划的这一方面提供了冰川历史模型,这些模型继续被国际社会普遍采用,以提供支持基于全球气候模型的过去气候条件重建所需的边界条件。除了继续对现代和过去的气候状态进行高分辨率区域气候建模的工作外,多伦多小组的一个独特贡献将是继续努力更充分地了解海洋同位素阶段3期间主导气候变化的所谓Dansgaard-Oeschger振荡现象。正如Peltier小组已经表明的那样,这些振荡是由快速冰流不稳定性触发的,称为Heinrich事件,对此也提出了一种新的理论,将在这项拟议的研究计划中进行更充分的探索。这一领域新研究的一个主要重点将是了解这种D-O现象对轨道日射状况的依赖性以及已经产生的成功模拟的其他特征。这些D-O结果已被证明依赖于小尺度海洋湍流过程的方式参数化的UofT气候模式的全球海洋组件,特别是海洋diapycnal扩散率的表示。多伦多方案的一个主要贡献继续涉及理论和数值模拟为基础的结果,导致显着改善在低分辨率海洋模型中的这种小尺度过程的表示。下一个资助期的一个特别重点将是内波破碎可能在多大程度上有助于海洋底辟扩散。这项工作得到了极高分辨率的MITgcm为基础的模拟与模型明确迫使天文潮汐和大气派生的表面强迫。这种基于正式流体力学分析的海洋湍流过程的重点是将在下一个赠款期间开展的工作所包括的一系列相关调查的最后一项。
