Parameterization of Processes in Models for Medium-Range Prediction and Global Climate Seminar, August 6-10, 1990 in Pune, India, Group Travel Award in U.S. & Indian Currenc

项目说明：本项目支持20名美国科学家参加将在浦那举行的“中期预测和全球气候动力学模式中亚网格尺度过程参数化”两国研讨会。印度，1990年8月6日至10日。印度合作科学家是印度浦那印度热带气象研究所（IITM）所长Dr. r. Sikka博士。研讨会计划讨论以下领域：对流（大尺度和积云尺度）、辐射、地形学、边界层通量、水文循环和生物圈过程。这些物理过程的参数化将在中期预报（通常长达10天）和全球气候的全球模式中进行研究。重点将放在热带地区，那里的动力场与参数化的对流、辐射和边界层过程之间的相互作用非常迅速。预计将对热带气候的控制有更好的了解，从而进一步改进中期预报和我们对全球气候变化的总体认识。讲习班还将设法确定合作研究的领域。讲习班会议记录预定出版。范围：美印在大气研究方面的合作可以追溯到20世纪70年代，以及1978年冬季和1979年夏季为期两年的MONEX实验。印度人对预测天气状况的兴趣是众所周知的，包括长期和中期预报。美国对季风环流的兴趣也非常浓厚，季风环流本身就是一个行星尺度的特征。浦那的印度理工学院有着悠久的热带研究历史。印度最近还在德里建立了一个国家中期天气预报中心（NCMRF），该中心拥有一台新获得的超级计算机。因此，美国和印度都有强烈的兴趣和资源来处理研讨会主题的研究问题。他们的合作可能会使两国受益。

Description: This project supports participation of 20 U.S. scientists in a binational workshop on "Parameterization of Subgrid-Scale Processes in Dynamical Model of Medium Range Prediction and Global Climate" to be held in Pune. India, August 6 to 10, 1990. The Indian cooperating scientist is Dr. D.R. Sikka, Director, Indian Institute of Tropical Meteorology (IITM), Pune, India. The workshop is planned to discuss the following areas: convection (large scale and cumulus scale), radiation, orography, boundary layer fluxes, hydrological cycle, and biosphere processes. The parameterization of these physical processes will be examined in global models for medium range forcasting (normally up to 10 days), and for global climate. Emphasis will be on the conditions in the tropics where the interaction between the dynamical fields and the parameterized convective, radiative and boundary layer processes is very rapid. It is expected that better understanding of the controls of tropical climate will result, leading to further improvements in medium range forcasting, and in our general understanding of global climate change. The workshop will also seek to identify areas for cooperative research. Workshop proceedings are scheduled to be published. Scope: U.S.-Indian cooperation in atmoshperic research stretches back to the 1970's and to the two year MONEX experiments in the winter of 1978 and summer of 1979. Indian interest in predicting weather conditions, both long-term and medium term forcasts, is well known. U.S. interest in the monsoon circulation, itself a planetary scale feature, is also very strong. The IITM in Pune has long history of tropical research. India also has recently established a National Center for Medium Range Weather Forcasting (NCMRF) in Delhi which has a newly acquired supercomputer. Thus both the U.S. and India have the strong interest and resources to deal with research problems of the workshop topic. Their collaboration is likely to benefit the two countries.
