Dynamical processes for coupling energy and momentum of the solar wind into the magnetosphere, for transporting and heating the plasma within its boundaries, and for coupling the motions of magnetopause and ionosphere have received increasing attention in recent years. This grant is for studies to examine a variety of processes that are important for the coupling of solar wind plasma through the magnetosphere and the magnetospheric cavity and into the ionosphere. Because of the nature of the studies, this grant will be part of the GEM (Geospace Environment Modelling) program. The project will focus on: 1) How pressure pulses in the solar wind affects the magnetosphere and ionosphere, 2) The structure and the ionospheric signatures of disturbances called Flux Transfer Events (FTE's) that are produced by bursty reconnection on the magnetopause, and 3) ionospheric boundaries conditions for ultralow frequency waves. ***

近年来，将太阳风的能量和动量耦合到磁层、在其边界内传输和加热等离子体以及耦合磁层顶和电离层运动的动力学过程受到越来越多的关注。这笔赠款用于研究各种对太阳风等离子体通过磁层和磁层空穴耦合并进入电离层的重要过程。由于研究的性质，这笔赠款将是GEM(地球空间环境建模)计划的一部分。该项目的重点是：1)太阳风中的压力脉冲如何影响磁层和电离层，2)磁层顶爆发重联产生的称为通量转移事件(FTE)的扰动的结构和电离层特征，以及3)超低频波的电离层边界条件。***
