Distributions of current density | j | and velocity deviations δv(x,z) around one of the energy release regions. Top left plot shows the global current density distribution at x = 0 plane and the location of the sampled region. Current density distribution and magnetic field lines in the selected region are shown in the top right panel. Distributions of the ρ²T-weighted velocity deviations (see text for details) are shown in the bottom left (x-component) and bottom right (z-component) panels. (Here the units of the current density colour scale are 3.6 × 10^-3 A m^-2 and the units of the ρ²T-weighted velocity colour scale are 2.8 × 10³ km s^-1). Distances are in 10⁶ m.
