项目摘要

The complexity of climate change at high latitudes presents many challenges to researchers interested in the atmospheric general circulation. For example, the last two years included the most extreme Artic sea ice minimum and the most rapid spring-to-summer retreat of Northern Hemisphere snow cover ever recorded. These years also featured extreme midlatitude weather events which some researchers have speculated are linked to recent Arctic change. Rapid climate change at high latitudes is taking place in the context of long term anthropogenic global change, is strongly influenced by climate feedbacks, and is connected to changes in the planetary scale general circulation of the atmosphere and oceans. But key aspects of high latitude climate change are not robustly predicted by climate models, and the climate feedbacks and dynamical coupling to the planetary-scale circulation of the atmosphere and oceans remain poorly understood. The PI leads an original basic research program whose long term objective is to better understand the atmospheric circulation outside the tropics, its variability on decadal timescales, its sensitivity to climate change, and its coupling to the environment. Alongside, in the last six years, he has developed and now leads a collaborative applied research program in Arctic and cryospheric modelling, focusing on prediction of snow cover and sea ice on seasonal to decadal timescales. The PI's basic research program centres on a hierarchy of climate models that ranges from novel configurations of simplified representations of the atmosphere to state of the art Earth System Models (ESMs) that endeavour to include the physical, biological, and chemical processes controlling Earth's climate. This basic research program is needed for the PI to be able to leverage his applied work to improve climate prediction and advance our understanding of climate. The PI's research aims, over the long term, to advance the theory of the atmospheric general circulation. Its primary application is towards climate change and variability at high latitudes. This Discovery Grant proposal is intended to support the PI’s basic research program for the next six years. The research's objectives over the next six years are1) To learn how high latitude climate is linked to variability associated with atmospheric planetary waves, with a focus on a so-called "linear interference effect" that the PI's group has explored in groundbreaking research.2) To understand the two-way connections between midlatitude and polar variability using a hierarchy of climate models of varying degrees of complexity, which has been a hallmark of the PI's successful theoretical research.3) To identify mechanisms in the coupled ocean atmosphere system controlling persistence and predictability of decadal climate signals in the midlatitudes, with a suite of comprehensive ESM simulations being generated using Canadian and international computing resources.4) To carry out targeted analysis on the impact of Arctic variability on the Arctic environment in the setting of lake dynamics studies, through collaborative research. The lake work will combine meteorological analysis with multiple-decade long Arctic lake records, as well as regional model representations of present day conditions and under conditions of projected global warming.The PI maintains a group of excellent undergraduate students, graduate students, postdoctoral fellows, and research associates to support his research program; they receive rigorous training and as a result advance well professionally. Resources requested in the proposal will go mainly to support students, and are intended to continue the applicant’s track record of high level training and follow on placement.
高纬度地区气候变化的复杂性给大气环流研究人员提出了许多挑战。例如,过去两年出现了最极端的北极海冰最小值,以及有记录以来北半球积雪从春季到夏季消退最快的时期。这些年来还出现了极端的中纬度天气事件,一些研究人员推测这与最近的北极变化有关。高纬度地区的快速气候变化是在长期人为全球变化的背景下发生的,受到气候反馈的强烈影响,并与行星尺度大气和海洋环流的变化有关。但是,气候模式对高纬度气候变化的关键方面并没有强有力的预测,气候反馈以及大气和海洋的行星尺度环流的动力耦合仍然知之甚少。PI领导了一个原始的基础研究项目,其长期目标是更好地了解热带以外的大气环流,它在年代际时间尺度上的变化,它对气候变化的敏感性,以及它与环境的耦合。此外,在过去的六年里,他开发并领导了一个北极和冰冻圈建模的合作应用研究项目,重点是在季节到十年的时间尺度上预测积雪和海冰。PI的基础研究项目以一系列气候模型为中心,从大气简化表示的新配置到努力包括控制地球气候的物理、生物和化学过程的最先进的地球系统模型(ESMs)。这个基础研究项目是PI能够利用他的应用工作来改善气候预测和推进我们对气候的理解所需要的。从长远来看,PI的研究旨在推进大气环流理论。它的主要应用是高纬度地区的气候变化和变率。这项发现拨款提案旨在支持PI未来六年的基础研究计划。未来六年的研究目标是:1)了解高纬度气候如何与大气行星波相关的变化相关联,重点关注PI小组在开创性研究中探索的所谓“线性干扰效应”。2)利用不同复杂程度的气候模式层次来理解中纬度和极地变率之间的双向联系,这是PI成功的理论研究的标志。3)利用加拿大和国际计算资源生成一套全面的ESM模拟,确定耦合海洋大气系统控制中纬度年代际气候信号持续性和可预测性的机制。4)在湖泊动力学研究的背景下,通过合作研究,有针对性地分析北极变率对北极环境的影响。湖泊工作将结合气象分析与几十年的北极湖泊记录,以及当前条件和预估的全球变暖条件下的区域模式表示。PI拥有一批优秀的本科生,研究生,博士后研究员和研究助理,以支持他的研究计划;他们接受严格的训练,因此在专业上取得了很好的进步。提案中要求的资源将主要用于支持学生,并旨在继续申请人的高水平培训记录并跟踪安置。
