Description: This award is to support a collaborative research between Drs. Sethu Raman and Leonard Pietrafesa of the North Carolina State University (NCSU), Raleigh, and Dr. P.A. Aswathanarayana of the Indian Institute of Technology, Madras (IITM), India. These scientists, in collaboration with the Indian National Institute of Ocean Technology (NIOT) on the IITM campus, plan to study Indian sea breezes, atmospheric convection along the see breeze front, and to also study the storm surge processes along the East coast of India (Bay of Bengal). In the first part, the scientists plan to investigate the horizontal extent of the sea breezes in relation to land-sea temperature differences and the ambient wind, and to study the formation of deep convection along the sea breeze front and its dependence on other factors such as land use pattern and upper air stability. They plan to primarily use a hydrostatic numerical model developed at NCSU and transferred to the IITM. This model will be extended to a 3-dimension state and used with atmospheric observations in India that is taken every three hours, and dating back for 30 years. The model may be supplemented with a non-hydrostatic model as needed. In the second part, the scientists will utilize a storm surge model available at the NIOT and based on Sea, Lake and Overland Surges from Hurricanes (SLOSH) model originally developed in the United States. They will develop methods to prescribe meteorological forces that drive the ocean model, and will also use a simple hydrodynamic model developed at NCSU and used in North Carolina during the occurrence of Hurricane Emily in 1993, with satisfactory results, in predicting this tropical storm surge. Scope: This award is to allow cooperation between a U.S. team that is quite active in modeling various atmospheric-sea-land phenomena, and an Indian team at the Madras campus that has excellent analytical capability as well as access to extensive data sources from numerous Indian research organizations. These governmental organizations operate radar, satellite, and other atmospheric and ocean measurement instrumentation on a continuous basis. The research is of significant scientific benefit to the United States and India, and is of particular importance to the meteorological activities of the Indian authorities in predicting severe climatic and weather conditions. The project involves eminent scientists and graduate students on both sides.

描述：该奖项是为了支持博士之间的合作研究。罗利市北卡罗来纳州立大学（NCSU）的Sethu Raman和Leonard Pietrafesa，以及印度马德拉斯印度理工学院（IITM）的P.A. Aswathanarayana博士。这些科学家与印度理工学院（IITM）的印度国家海洋技术研究所（NIOT）合作，计划研究印度海风、沿海风锋面的大气对流，以及沿印度东海岸（孟加拉湾）的风暴潮过程。在第一部分中，科学家计划调查海风的水平范围与海陆温差和环境风的关系，并研究沿海风锋形成的深层对流及其对土地利用模式和高空稳定性等其他因素的依赖。他们计划主要使用NCSU开发并转移到IITM的流体静力学数值模型。该模型将扩展到三维状态，并用于每三小时进行一次的印度大气观测，可追溯到30年前。该模型可根据需要补充非流体静力模型。在第二部分，科学家们将利用NIOT提供的风暴潮模型，该模型基于最初在美国开发的海、湖和陆地飓风（SLOSH）模型。他们将开发方法来规定驱动海洋模型的气象力量，并将使用NCSU开发的一个简单的流体动力学模型，该模型在1993年艾米丽飓风发生时在北卡罗来纳州使用，并取得了令人满意的结果，以预测这次热带风暴潮。范围：该奖项允许在模拟各种大气-海洋-陆地现象方面相当活跃的美国团队与马德拉斯校区的印度团队进行合作，该团队具有出色的分析能力，并可以从众多印度研究机构获得广泛的数据来源。这些政府组织在持续的基础上操作雷达、卫星和其他大气和海洋测量仪器。这项研究对美国和印度具有重要的科学意义，对印度当局预测恶劣气候和天气条件的气象活动尤其重要。这个项目涉及双方的著名科学家和研究生。
