Atmospheric Responses to North Pacific Sea Surface Temperture Anomalies During Winter and Summer

摘要ATM-9506368 Ting，Mingfang University of Illinois题目：冬夏季大气对北太平洋海表温度异常的响应 该建议概述了一个全面的研究和教学计划，这将提高PI的她在伊利诺伊大学的学术生涯的早期发展。 “生涯”研究包括冬、夏季北太平洋海表温度（SST）异常对热带外大气的动力影响。 大气对持续中纬度海温异常的响应在过去一直存在争议。 困难部分源于中纬度大气的自然变率非常大，因此信噪比很小。 这个问题也被这样一个事实所笼罩，即大气环流模式（GCM）的实验与固定的热带外SST异常并不总是产生一致的响应。 该项目将集中研究北太平洋海温异常及其对太平洋和北美气候的可能影响。 该研究的一个新方面是，它将利用一系列的建模工具，包括线性稳态模型，干GCM和完整的GCM。 PI还将首次研究北太平洋海温异常对夏季的影响。 这项研究的结果有望改善太平洋和北美地区的季节性预报。 特别是，夏季的结果将有助于中西部干旱和洪水潜力的长期预测。 教育计划包括创新的本科教学和开发研究生课程，这是目前在PI的部门不可用。 本科教学计划的一个新颖方面将是通过伊利诺斯大学的计算机网络向来自不同学科的学生介绍当前的天气信息，并帮助学生解释数据。 新的研究生课程的主要目标是向研究生介绍一个迅速发展的领域，即海洋-大气耦合过程的最新研究课题。 内容包括热带太平洋海气耦合作用，即厄尔尼诺/南方涛动现象，中纬度海气耦合，热带30-60天振荡的海气耦合。

Abstract ATM-9506368 Ting, Mingfang University of Illinois Title: Atmospheric Responses to North Pacific Sea Surface Temperature Anomalies During Winter and Summer This proposal outlines a comprehensive research and teaching plan which will enhance the PI's early development of her academic career at the University of Illinois. The "career" research involves the study of the dynamical effect of the North Pacific sea surface temperature (SST) anomalies on the extratropical atmosphere during both winter and summer seasons. The atmospheric responses to persistent midlatitude SST anomalies has been controversial in the past. The difficulties stem partly from the fact that the natural variability of the midlatitude atmosphere is very large, thus there is a small signal to noise ratio. This problem is also clouded by the fact that general circulation model (GCM) experiments with fixed extratropical SST anomalies do not always produce a consistent response. This project will concentrate on the North Pacific SST anomalies and their possible impact on the Pacific and North American climate. One novel aspect of the research is that it will make use of a series of modeling tools, including a linear steady state model, a dry GCM and a full GCM. The PI will also, for the first time, look int the effect the North Pacific SST anomalies for the summer season. The results of this research are expected to improve the seasonal forecasting for the Pacific and North American region. In particular, the results from the summer season will help the long range prediction of the mid-west drought and flood potentials. The education plan consists of innovative undergraduate teaching and developing a graduate course that is currently not available in the PI's department. One novel aspect in the undergraduate teaching plan will be to introduce students from various disciplines to the current weather information through the computer network at the University of Illinois and to help students interpret the data. The main objective of the new graduate course is to introduce the graduate students to the most up-to date research topics in an area that is rapidly evolving, namely the coupled ocean-atmosphere processes. The topics include the coupled air-sea interaction in the tropical Pacific, i.e, the El Nino/Southern Oscillation phenomenon, the air-sea coupling in the midlatitude, and the air-sea coupling for the tropical 30-60 day oscillations.
