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

摘要ATM-9506368 Ting，伊利诺伊明方大学题目：冬季和夏季大气对北太平洋海面温度异常的响应这项建议概述了一项全面的研究和教学计划，这将促进PI在伊利诺伊大学的早期学术发展。“职业”研究包括研究冬夏两季北太平洋海温异常对温带大气的动力影响。大气对持续的中纬度SST异常的响应在过去一直存在争议。困难的部分原因是，中纬度大气的自然变率很大，因此信噪比很小。用固定的温带外SST异常进行的大气环流模式(GCM)实验并不总是产生一致的响应，这一事实也给这个问题蒙上了一层阴影。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。研究的一个新颖方面是，它将利用一系列建模工具，包括线性稳态模型、干GCM和全GCM。PI还将首次研究夏季北太平洋海温异常的影响。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旱涝潜力的长期预报。教育计划包括创新的本科教学和开发一门研究生课程，这是目前PI部门无法提供的。本科教学计划的一个新方面将是通过伊利诺伊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，并帮助学生解读这些数据。新的研究生课程的主要目标是向研究生介绍一个正在迅速发展的领域的最新研究课题，即海洋-大气耦合过程。主题包括热带太平洋的海气耦合作用，即厄尔尼诺/南方涛动现象，中纬度的海气耦合，以及热带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.
