Study of the Tropical Atmospheric Boundary Layer During Various Phases of the Indian Monsoon, A Guest Scientist Award in Indian Currency

描述：该项目支持一名美国科学家从他的大学到印度两所著名的学术机构--班加罗尔的印度科学研究所(IIS)和新德里的印度理工学院(IIT)--休假。在此期间，拉曼博士将继续他目前在行星边界层(PBL)、季风动力学和空气污染方面的研究，与IIS班加罗尔和IIT德里的大气科学中心(CAS)的科学家们合作。他将增加关于对流和稳定条件以及季风动力学的陆地热带边界结构的工作。他将参与中科院一项为期三年的实验的设计，以研究印度西南季风期间通常位于恒河平原的季风槽中的边界层结构。在德里，他将进行空气污染气象学研究和区域尺度天气预报模式的PBL参数化工作。他的联系人是中科院、班加罗尔的R.N.艾扬格教授和印度理工学院德里的M.P.辛格教授。范围：P.I.是美国热带天气模拟方面的领先专家之一，尤其是与印度次大陆有关的热带天气模拟。他在与印度科学家一起进行研究方面有很长的经验，这些研究得到了美国国家科学基金会的几笔拨款。其中一位印度合作者(艾扬格博士)是印度科学研究所大气科学中心的代理主任，该研究所是印度顶尖的研究机构之一，拥有优秀的工作人员和设施，并有精心规划的研究议程。新德里印度理工学院的M.P.Singh博士是大气科学中心主任，拥有一大批主要从事大气模型和空气污染研究的工作人员。辛格博士和拉曼多年来一直在一个项目上合作，该项目涉及将美国学生送到印度进行实地考察。这个项目有可能产生重大成果。

Description: This project supports a U.S. scientists to spend a sabbatical from his university at two prestigious academic institutions in India, namely the Indian Institute of Science (IIS) in Bangalore, and the Indian Institute of Technology (IIT) in New Delhi. During that period Dr. Raman will continue his current collaborative research on planetary boundary layer (PBL), monsoon dynamics and air pollution, with scientists from the Center for Atmospheric Sciences (CAS) at IIS Bangalore and at IIT Delhi. He will increase his work on tropical boundary structures over land for both convective and stable conditions and monsoon dynamics. He will participate in the design of a three-year experiment at CAS for the study of the boundary layer structure in the monsoon trough normally located along the Gangetic plains during Indian southwest monsoon. At Delhi he will conduct research on air pollution meteorology and the work on PBL parameterization for Regional Scale Weather Forecasting Models. His contacts are Professors R.N. Iyengar at CAS, Bangalore and M.P. Singh at IIT Delhi. Scope: The P.I. is one of the leading experts in the U.S. on modeling of tropical weather, especially as related to the Indian subcontinent. He has long experience in conducting research with Indian scientists under several grants from NSF. One of the Indian collaborators (Dr. Iyengar) is Acting Head of the Center for Atmospheric Sciences at the Indian Institute of Science, one of India's top research institutes with excellent staff and facilities and with well planned research agenda. Dr. M.P. Singh at the Indian Institute of Technology in New Delhi is the Director of the Center for Atmospheric Sciences, and has a large staff engaged primarily in atmospheric modeling and air pollution studies. Drs. Singh and Raman have been collaborating for several years on a project that involved sending U.S. students for field studies in India. This project has the potential to produce significant results.
