Investigations of the Geodynamo

Bloxham公司的E-0073988调查的地球发电机过程，是负责产生地球磁场的建议。将讨论以下方面：1.地球发电机最新数值模型中磁场产生的基本机制研究。2.研究数值发电机模型的参数状态，特别是寻求进一步理解惯性和粘性效应对地球发电机的作用。3.研究热核幔相互作用及其在控制主磁场形态和长期变化中的作用。4.内核引力耦合对地球发电机影响的研究。5.用数值发电机模型分析核幔边界磁场图中观测到的特征。6.冻结通量近似的分析。7. Dynamo代码开发，包括开发适合在基于Intel x86的机器网络上运行的分布式内存版本的代码，以及社区Dynamo模型的初始开发。

Bloxham EAR -0073988 Investigations of the geodynamo process that is responsible for generation of the Earth's magnetic field are proposed. The following areas will be addressed: 1. Investigation of the basic underlying mechanisms of magnetic field generation in recent numerical models of the geodynamo. 2. Investigation of the parameter regime of numerical dynamo models, seeking in particular to further our understanding of the role of inertial and viscous effects on the geodynamo. 3. Investigation of thermal core-mantle interactions and their role in controlling the morphology of the main field and its secular variation. 4. Investigation of the effect of inner core gravitational coupling on the geodynamo. 5. Analysis of features observed in maps of the magnetic at the core-mantle boundary using a numerical dynamo model. 6. Analysis of the frozen-flux approximation. 7. Dynamo code development, including development of a distributed memory version of the code suitable for running on a network of Intel x86 based machines, and initial development of a community dynamo model.
