AbstractATM-9903503Robinson, WalterUniversity of IllinoisTitle: Dynamics of Atmospheric Response to Midlatitude SST AnomaliesThe collaborative research (Peng/Univ. Co Boulder and Robinson/Univ. Ill Urbana Champaign) will develop a better understanding of the dynamics involved in generating an equivalent-barotropic ridge response to midlatitude SST anomalies. The impact of the response on midlatitude atmosphere-ocean interactions will also be examined. There are three components to this project (a) idealized model experiments; (b) GCM experiments and (c) mechanistic diagnoses. The idealized models will be used to find optimal locations in the Pacific and the Atlantic for warm SSTs to trigger the strongest positive eddy feedback favorable for robust ridge responses. The PIs will test predictions from the idealized model experiments using the GCM. The work is important because it will increase understanding of the role of midlatitude SSTs in climate variability.

罗宾逊，沃尔特伊利诺斯大学题目：大气对中纬度SST异常的响应动力学这项合作研究（彭/博尔德大学和罗宾逊/伊利诺伊大学厄巴纳尚潘分校）将更好地理解对中纬度SST异常产生等效正压脊响应所涉及的动力学。 还将研究这种反应对中纬度大气-海洋相互作用的影响。这个项目有三个组成部分 (a)理想模型实验;（B）GCM实验;（c）机理诊断。理想化的模式将被用来寻找最佳的位置在太平洋和大西洋温暖的SST触发最强的正涡反馈有利于强大的脊响应。PI将使用GCM测试理想化模型实验的预测。这项工作很重要，因为它将增加对中纬度SST在气候变率中的作用的理解。
