The research will use a variable-resolution stretched-grid general circulation model (SG-GCM) to conduct climate studies on anomalous regional events. The following issues will be addressed: (a) numerical experimentation with new emerging SG-GCMs incorporating land-surface models; (b) simulation at seasonal and interannual temporal scales, and regional-to-global spatial scales; (c) improved understanding and modeling of processes that affect regional climate variability. The major goals are simulating the 1997-1999 El Nino Southern Oscillation and related monsoon circulation with 25-40 km and finer resolution; studying intraseasonal and interannual regional climate variability for the extended multiyear SG-GCM simulations; studying the impact of sea surface temperatures and land-surface forcing on SG-GCM simulations; studying the impact of ensemble integrations; and developing educational tools for students. The work is important because the SG-GCM formalism may prove to be a viable new approach to regional and subregional climate studies and applications.

该研究将使用可变分辨率拉伸网格大气环流模型（SG-GCM）对异常区域事件进行气候研究。将解决以下问题： (a) 采用结合陆地表面模型的新型 SG-GCM 进行数值实验； (b) 季节和年际时间尺度以及区域到全球空间尺度的模拟； (c) 更好地了解影响区域气候变化的过程并对其进行建模。主要目标是模拟1997-1999年厄尔尼诺南方涛动和相关的季风环流，分辨率为25-40公里；研究季节内和年际区域气候变化，以进行扩展的多年 SG-GCM 模拟；研究海面温度和陆地表面强迫对 SG-GCM 模拟的影响；研究集成集成的影响；为学生开发教育工具。这项工作很重要，因为 SG-GCM 形式可能被证明是区域和次区域气候研究和应用的可行新方法。
