| We analyze five solar Explosive Events observed in the Si IV emission line at 139.37 nm during SUMER/SoHO raster scans near disk center. The Doppler velocities from ‒45 km s⁻¹ to +45 km s⁻¹ were sorted into eleven symmetrically organized velocity bins, five equally-sized bins on each side and one bin for the line at rest. The radiance values along the NS oriented slit around the maximum of each EE are used to build one-dimensional distributions. We study these distributions and their development in space and time for different velocity bins to unveil the 3D-structure and evolution of Explosive Events. The spatial radiance distributions for the EE maximum and around it were made. For some Explosive Events the dispersion direction is not oriented orthogonally to the slit direction; consequently, the blueshifted emission is in a linear way offset from the redshifted emission by several pixels. The largest offset (~5’’) is observed between distributions whose velocities differ by ~36 km s⁻¹. The linear relation agrees with an scenario of flows inside magnetic arcs. | |
