US-U.K. Cooperative Research: Structure and Dynamic of the Earth's Interior Long-term Research Visit to Cambridge

该奖项将支持佛罗里达州立大学大卫·洛珀博士和英国剑桥大学应用数学和理论物理系H.K.莫法特教授之间的合作研究。在剑桥大学为期一年的研究访问期间，洛珀博士将研究地球内部的结构和动力学，包括由成分浮力驱动的核心运动的结构，流体运动的发电机作用，以及部分凝固系统的基础研究。在过去的十年里，由于应用了物理原理和数学分析，我们对地球内部深处的结构和动力学的理解取得了重大进展。洛珀博士之前曾对发电机能量供应的性质和地幔底部的D“层结构进行过研究。在拟议的访问期间，这些专题将向几个方向延伸。特别是，他将研究地球外核中可能支持地球发电机的特定运动场。莫法特博士和他在剑桥大学的同事在这一研究领域拥有丰富的专业知识。洛珀博士是一名应用数学家，通过对地核和地幔的动力学和热力学性质的研究，他已经成为一名专业的理论地球物理学家。

This award will support collaborative research between Dr. David Loper Florida State University and Professor H. K. Moffatt, Department of Applied Mathematics and Theoretical Physics, University of Cambridge, England. During a one year research visit at Cambridge, Dr. Loper will study the structure and dynamics of the Earth's interior, including the structure of core motions driven by compositional buoyancy, dynamo action of fluid motions and fundamental studies of partially solidified systems. The past decade has seen significant advances in our understanding of the structure and dynamics of the Earth's deep interior, brought about by the application of physical principles and mathematical analysis. Dr. Loper has carried out previous work on the nature of the dynamo energy supply and the structure of the D" layer at the base of the mantle. During the proposed visit, these topics will be extended in several directions. In particular, he will investigate specific motion fields in the Earth's outer core which may sustain the geodynamo. Dr. Moffat and his colleagues at Cambridge have significant expertise in this area of research. Dr. Loper is an applied mathematician, who has become an expert theoretical geophysicist through his research on dynamical and thermodynamical properties of the core and mantle of the Earth.
