US-India Cooperative Research: Studies of Mesoscale (beta and gamma) Weather Systems over Indian Region Using Regional Atmospheric Modelling System of Colorado State University

该合同支持美印合作研究项目：利用科罗拉多州立大学（CSU）的区域大气模拟系统（RAMS）研究印度地区的中尺度天气系统。科罗拉多州立大学的美国PI William Cotton将与印度热带气象研究所（IITM）的PI S.S. Singh合作。利用印度次大陆的RAMS，研究人员希望确定中尺度天气系统的可预测性、边界层的夹带以及控制季风月份降水日变化的机制。范围：科罗拉多州立大学将接待印度联合项目负责人，让他熟悉RAMS，美国项目负责人将访问印度理工学院，就RAMS的应用发表演讲。科罗拉多州立大学是RAMS计算机模型的开发者，拥有对天气系统进行复杂模拟的资源。印度理工学院的科学家对印度次大陆的天气系统非常有经验，并且已经确定了我们对这些天气系统的理解中的关键未知因素。这种合作可能会对我们了解该地区的天气系统做出重大贡献，并确定如何改进预测。

US PI William Cotton, Colorado State University will collaborate with Indian PI S.S. Singh, Indian Institute of Tropical Meteorology (IITM). Using RAMS for the Indian sub-continent, the researchers expect to identify-- predictability of mesoscale weather systems, entrainment in the boundary layer, and mechanisms controlling diurnal variations in precipitation during monsoon months. Scope: Colorado State will host the Indian co-PI to acquaint that person with RAMS and the US PI will visit the IITM to present lectures on applications of RAMS. Colorado State is the developer of the RAMS computer model and has the resources to perform complex simulations of weather systems. The IITM scientists are very experienced with weather systems over the Indian sub-continent and have identified key unknowns in our understanding of those weather systems. This collaboration is likely to make a major contribution to our understanding of weather systems in that region and identify how predictions can be improved upon.
