Results of high-resolution SWMF/BATS-R-US simulation with 1/16 R_E grid resolution in the tail and magnetopause region in order to resolve small and mesoscale structures. It shows the filamentary current structures associated with the presence of both Kelvin–Helmholtz vortices at the flanks of the magnetopause and of bursty structures in the tail. Note that the associated flow velocities are not shown (Dorelli & Buzulukova, personal communications, 2020).
