This project will utilize magnetohydrodynamic (MHD) simulations of the magnetosphere-ionosphere system to examine the sensitivity of MHD simulations to variability of the solar wind driver. The work will compare the variability induced by intrinsic, internal magnetospheric dynamics with the variability caused by both temporal and spatial variability in the solar wind. Case studies will be done with real events to allow for comparisons of the simulations with realistic conditions. This work will provide a mechanism for determining the accuracy with which MHD models might in the future be able to predict space weather conditions.

该项目将利用磁层-电离层系统的磁流体动力学(MHD)模拟来检查MHD模拟对太阳风驱动器的可变性的敏感性。这项工作将比较由内在的内部磁层动力学引起的变异性与由太阳风的时间和空间变异性引起的变异性。将用真实事件进行案例研究，以便将模拟与现实条件进行比较。这项工作将提供一种机制，用于确定MHD模型未来可能能够预测空间天气条件的精度。
