项目摘要

9313256 Raman Description: This project will support two scientists, Dr. Sethu Raman, of North Carolina State University, and M.P. Singh, of the Indian Institute of Technology, New Delhi, and their graduate students, to continue and complete a collaborative research on the observations and modeling of atmospheric turbulence and diffusion at low wind speeds. The main objective of the study is to determine the variation of turbulence and diffusion processes in the surface layer during daytime convective conditions and nighttime stable conditions. Another part involves test and development of a reliable model to predict diffusion in low wind speeds. Scope: This project deals with modeling of weather conditions in a tropical area, which applies to many of the countries in South Asia and South East Asia. The two scientists have set up elaborate facilities in India for measuring atmospheric conditions at all times, and are developing and adapting computer models that can be tested and modified to best describe the prevailing conditions in the region. The completion of the work is important to reach reliable models of dispersion at low wind speeds. Such models have many applications such as in predicting dispersion of industrial or chemical pollutants in warm climates. The interaction between the U.S. and Indian sides is clearly beneficial to the research of the two scientists and in developing new human resources in the two countries. ***

9313256拉曼描述：该项目将支持两位科学家，北卡罗来纳州立大学的塞图·拉曼博士和新德里印度理工学院的M.P.辛格，以及他们的研究生，继续并完成一项关于低风速下大气湍流和扩散的观测和建模的合作研究。研究的主要目的是确定白天对流和夜间稳定条件下近地面层湍流和扩散过程的变化。另一个部分是测试和开发一个可靠的模型，以预测低风速下的扩散。范围：这个项目涉及热带地区天气条件的模拟，适用于南亚和东南亚的许多国家。这两位科学家在印度建立了精密的设备，随时测量大气条件，并正在开发和调整计算机模型，这些模型可以进行测试和修改，以最好地描述该地区的普遍条件。这项工作的完成对于在低风速下获得可靠的扩散模型是很重要的。这类模型有许多应用，例如在预测工业或化学污染物在温暖气候中的扩散。美印双方的互动显然有利于两位科学家的研究，并有助于在两国开发新的人力资源。***
