Extratropical Climate Variability in the Coupled Ocean- Atmosphere System

美国威斯康星大学戴维·D·霍顿的ATM-9510183研究题目：海洋-大气耦合系统中的温带气候变率这项研究的重点是了解和分离与以下有关的关键物理机制：1)热带-温带相互作用对北太平洋温带区域年际变率的影响；2)北太平洋的年代际气候变率；3)过渡季热带外大气流量的突变。来自一系列数值模型的模拟与观测的验证为分析提供了基本数据。仔细的诊断将能够隔离特定的进程。这种隔离对于发展理论和理解完全耦合模型的结果是至关重要的。来自全球数据集的观测不仅将用于模型参数的指定和验证，还将用于与模型研究中发现有用的诊断分析平行的诊断分析。这一研究项目的一个优势是代表海洋和大气科学界的科学家的密切合作。这将使它们能够充分纳入海洋-大气系统的关键机制，这些机制对于变化的各种时间尺度都很重要。

Abstract ATM-9510183 Houghton, David D. University of Wisconsin Title: Extratropical Climate Variability in the Coupled Ocean- Atmosphere System This research is focused on understanding and isolating key physical mechanisms related to: 1) the effects of tropical- extratropical interactions on interannual variability in the extratropical North Pacific region, 2) decadal climate variability in the North Pacific, and 3) abrupt shifts in the extratropical atmospheric flow in the transition seasons. Simulations from a hierarchy of numerical models with validation from observations provide the basic data for analysis. Careful diagnostics will enable isolation of specific processes. Such isolation is critical for developing theory and for understanding results from fully coupled models. Observations from global data sets will be used not only for model parameter specification and validation, but also for diagnostic analyses parallel to those that are found useful in the model studies. A strong point for this research project is the close collaboration of scientists representing both the oceanographic and atmospheric science communities. This will enable them to adequately incorporate the key mechanisms of the ocean-atmospheric system important to the various time scales of variability.
