We use the global magnetohydrodynamic (MHD) code BATS‐R‐US to model multipoint observations of Flux Transfer Event (FTE) signatures. Simulations with high spatial and temporal resolution predict that cavities of weak magnetic field strength protruding into the magnetosphere trail FTEs. These predictions are consistent with recently reported multi‐point Cluster observations of traveling magnetopause erosion regions (TMERs).
