US-India Cooperative Research: Effect of Realistic Eurasian Snow Cover on Indian Summer Monsoon-- Numerical Experiments with Regional Model, Award in Indian Currency

9732685冲刺描述：该奖项支持美印合作研究：现实的欧亚积雪对印度夏季风的影响--区域模式的数值试验。合作者是马里兰大学气象系的US Pi Anandu D.Vernekar和新德里印度理工学院大气科学中心的India Pi S.K.Dash。这项研究考察了欧亚积雪对印度季风年际变化的影响。关于冬季欧亚积雪过多对随后的印度夏季风降水有不利影响的假设，将通过与全球大气环流模式相联系的高分辨率区域模式的数值试验来研究。这一结果将对印度季风的爆发和强度具有重要的预报价值。范围：这是一个连接马里兰大学气象系和德里印度理工学院大气科学中心的新合作项目。该项目将马里兰州的Vernekar小组在用一般和区域模式进行数值试验方面的开创性专门知识与德里小组在模拟大气和海洋过程方面的能力结合起来。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。***

9732685 Dash 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. ***
