A Three-Dimensional, Global-Scale Hybrid Code of the Earth's Magnetosphere

研究人员将开发一种完整的三维混合代码来模拟磁鞘-磁层-电离层耦合系统的动力学。其目的是填补我们对空间天气现象认识上的空白，并为新一代空间天气预报系统奠定基础。该项目是成功应用二维全球尺度混合代码来模拟午夜子午面磁层的结果。该代码将有可能对磁层对太阳风通量和嵌入的行星际磁场变化的响应进行建模。该模型的扩展将允许对磁感应效应进行预测，这对电力行业非常重要。该代码将为北极地区超级计算机中心的一台大规模并行计算机开发。所开发的技术将对实验室设备中的等离子体模拟和微波设备的设计产生重要的副产品。

The investigators will develop a full, three-dimensional hybrid code to simulate the dynamics of the coupled magnetosheath-magnetosphere-ionosphere system. The objective is to fill in the gaps in our understanding of space weather phenomena and provide a foundation for a new generation of space weather forecasting systems. The project is an outgrowth of a successful application of a two-dimensional global-scale hybrid code to model the magnetosphere in the midnight meridian plane. The code will make it possible to model the response of the magnetosphere to variations in the solar wind flux and imbedded interplanetary magnetic field. Extensions of the model will allow predictions of magnetic induction effects, which are of importance to the electric power industry. The code will be developed for a massively parallel computer at the Arctic Region Supercomputer Center. The techniques developed will have important spin-offs for simulation of plasmas in laboratory devices and design of microwave devices.
