Space Weather: Effects of the Solar Wind Variability on Magnetosphere-Ionosphere Weather Predictions

本项目将利用磁层-电离层系统的磁流体动力学（MHD）模拟来检验MHD模拟对太阳风驱动变率的敏感性。这项工作将比较由内在的、内部的磁层动力学引起的变率与由太阳风的时空变率引起的变率。案例研究将在真实事件中进行，以便将模拟与现实情况进行比较。这项工作将提供一种机制，用于确定MHD模型在未来能够预测空间天气条件的准确性。

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.
