This is a project to develop a model that specifies and forecasts the conditions of the magnetospheric bow shock, magnetosheath, magnetosphere, and ionosphere for given upstream solar wind conditions. The study extends work currently being funded under the High Performance Computing and Communication (HPCC) program. While this code is utilizing advanced numerical schemes to achieve the best efficiency and accuracy, additional work is needed to apply it to space weather objectives. The effort consists of three major components. First, realistic physical parameters and boundary conditions will be used to guide the model development. Second, the physical understanding of space weather events will be used to develop other theoretical models. And third, the investigators will compare the model output with observations for specific space weather events. The end product of the project is a global MHD simulation code able to both specify and forecast the state of the near-Earth space environment.

这是一个开发模型的项目，该模型可以指定和预测给定上游太阳风条件下磁层弓形激波、磁鞘、磁层和电离层的条件。 这项研究扩展了目前在高性能计算和通信（HPCC）计划下资助的工作。 虽然该代码利用先进的数值方法来实现最佳效率和准确性，但还需要开展更多的工作将其应用于空间气象目标。 这项工作包括三个主要部分。 首先，将使用真实的物理参数和边界条件来指导模型开发。 其次，对空间气象事件的物理理解将用于开发其他理论模型。 第三，研究人员将把模型输出与特定空间天气事件的观测结果进行比较。 该项目的最终产品是一个全球磁流体动力学模拟代码，能够说明和预测近地空间环境的状态。
