The coupling mechanisms of the solar wind to the magnetosphere and thence to the ionosphere are one of the primary problems in space physics today. The research program proposed here will examine this topic by using a very sophisticated computer model, which is being developed my mission Research Corporation. The model, referred to as the integrated Space Weather prediction model (ISM), used MHD global simulations to simulate the solar wind-magnetosphere system. it also can use a physics based ionospheric model to control the coupling of the magnetosphere to the ionosphere. The specific topics which will be investigated under this proposal include the mechanism by which plasma from the solar wind gains entry to the magnetosphere, and the macroscale properties of the dayside merging line and associated structures such as the plasma mantle and weak magnetic field regions (the "magnetospheric sash"0)

太阳风与磁层以及磁层与电离层的耦合机制是当今空间物理学的主要问题之一。这里提出的研究计划将通过使用一个非常复杂的计算机模型来研究这个问题，这个模型是我的使命研究公司正在开发的。该模型被称为综合空间气象预测模型，使用磁流体动力学全球模拟来模拟太阳风-磁层系统。它还可以使用基于物理学的电离层模型来控制磁层与电离层的耦合。根据这一建议，将研究的具体课题包括太阳风等离子体进入磁层的机制，以及昼侧合并线和相关结构（如等离子体地幔和弱磁场区（“磁层环带“））的宏观性质
