GEM Postdoc: Magnetosphere-Ionosphere Coupling Aspects of Traveling Convection Vortices

本计画将研究产生行对流涡旋（TCVs）的中尺度磁层-电离层耦合过程。tcv最初被认为是磁层顶通量转移事件的电离层特征，但现在这在很大程度上已经被忽视了。该项目将寻找可以结合地面电离层观测使用共轭卫星数据的TCV事件。将使用包括FAST、DMSP、Oersted和CHAMPS卫星在内的几颗卫星的数据。GEOTAIL卫星提供的数据也将用于统计信息。磁流体动力学（MHD）建模将用于确定观测到tcv时M-I系统的动态状态。

This project will examine the meso-scale magnetosphere-ionosphere coupling processes which create traveling convection vortices (TCVs). TCVs were originally thought to be the ionospheric signature of flux transfer events at the magnetopause, but this has now been largely discounted. The project will search for TCV events where conjugate satellite data can be used in conjunction with the ground-based ionospheric observations. Data from several satellites will be used including the FAST, DMSP, Oersted and CHAMPS satellites. Data from the GEOTAIL satellite will also be for statistical information. Magnetohydrodynamic (MHD) modeling will be done to determine the dynamical state of the M-I system when TCVs are observed.
