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.

本项目将研究中尺度磁层-电离层耦合过程，该过程产生移动对流涡旋（TCV）。 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被低估了。 该项目将寻找TCV事件，其中共轭卫星数据可与地面电离层观测结合使用。 将使用几颗卫星的数据，包括FAST、DMSP、Oersted和CHAMPS卫星。 来自GEOTAIL卫星的数据也将用于统计信息。 磁流体动力学（MHD）的建模将被用来确定的M-I系统的动态状态时，TCV的观察。
