US-India Cooperative Research: The Effects of Realistic Eurasian Snow Cover on the Indian Monsoon- A Numerical Experiment with A Regional Model

该奖项支持美国-印度合作研究：欧亚大陆实际积雪对印度夏季风的影响——一个区域模式的数值试验。合作者是美国马里兰大学气象系的PI Anandu D. Vernekar和印度新德里印度理工学院大气科学中心的PI S.K. Dash。本研究考察了欧亚大陆积雪对印度季风年际变化的影响。关于欧亚大陆冬季过度积雪对随后的印度夏季季风降雨有不利影响的假设，将通过与全球环流模式相联系的高分辨率区域模式的数值实验进行研究。研究结果对印度季风的发生和强度具有重要的预测价值。范围：这是马里兰大学气象系和德里印度理工学院大气科学中心的一个新的合作项目。该项目结合了Vernekar在马里兰的小组在数值实验方面的开创性专业知识，以及德里小组在模拟大气和海洋过程方面的能力。美国国家大气研究中心（NCAR）将提供克雷超级计算机设备来支持这项研究。＊＊＊

9728755 Vernekar Description: This award supports the US-India Cooperative Research: The Effects of Realistic Eurasian Snow Cover on the Indian Summer Monsoon-- A Numerical Experiment with a Regional Model. The collaborators are US PI Anandu D. Vernekar, Department of Meteorology, University of Maryland and Indian PI S.K. Dash, Centre for Atmospheric Sciences, Indian Institute of Technology, New Delhi. This research examines the effect of the Eurasian snow cover on the interannual variability of the Indian monsoon. The hypothesis that excessive winter Eurasian snow cover has adverse effect on the subsequent summer monsoon rainfall over India will be studied through numerical experiments on a high resolution regional model linked to a global general circulation model. The results will have important predictive value about the onset and strength of the Indian monsoon. Scope: This is a new collaboration linking the Department of Meteorology, University of Maryland and the Center for Atmospheric Sciences, Indian Institute of Technology, Delhi. This project combines the pioneering expertise of Vernekar's group at Maryland in numerical experiments with general and regional models with the capability of the Delhi group in modeling atmospheric and ocean processes. The National Center for Atmospheric Research (NCAR) will provided Cray supercomputer facilities to support this research. ***
