AbstractATM-9901110Barnett, TimUniversity of California, San DiegoTitle: Interaction of Regional Climate Modes: A Global Hypermode?The proposed work aims to test the idea that there are one or more global 'hypermodes' of climate variability composed of mutually interacting regional climate features or 'modes'. A coherent physical framework that can explain the observed decadal variation in regional climate, is sought in terms of the interactions between climate changes in other parts of the globe. The challenge is to describe the statistical relationships that exist between well known regional climate features (the Monsoon, ENSO, North Pacific Oscillation) and physical processes that govern these interactions. The nonstationary character of the statistical relations or interdecadal modulation makes this difficult. A set of long global climate model simulations from three different models, with/without full ocean physics, will serve as the basic data source for the study. The main thrust of this work is that for reliable climate prediction, regional climate changes need to be understood in a global context. The work is important because it will yield an enhanced understanding of the processes contributing to climate variability.

摘要ATM-9901110 Barnett，Tim加州大学圣地亚哥分校标题：区域气候模式的相互作用：全球超模式？拟议的工作旨在测试的想法，有一个或多个全球气候变率的“超模态”组成的相互作用的区域气候特征或“模式”。从地球仪其他地区气候变化之间的相互作用方面寻求一个连贯的物理框架，以解释观测到的区域气候的年代际变化。目前的挑战是要描述众所周知的区域气候特征（季风、厄尔尼诺/南方涛动、北太平洋涛动）与控制这些相互作用的物理过程之间存在的统计关系。统计关系或年代际调制的非平稳特征使这一点变得困难。从三个不同的模式，有/没有完整的海洋物理学，一套长期的全球气候模型模拟将作为研究的基本数据来源。 这项工作的主旨是，为了进行可靠的气候预测，需要在全球范围内了解区域气候变化。这项工作很重要，因为它将加深对造成气候变异的过程的理解。
