Properties of two distinct SSHEs in the LRM and HRM over their lifetimes which start to occur in two different locations of the solar atmosphere. The properties of the SSHE_A with a lifetime of 30 s are shown in the two left columns and the properties of the SSHE_B with a lifetime of 150 s are shown in the two right columns. The asterisks in the first and third columns from the left give the energy dissipation at the maximum energy dissipation location of the SSHEs, the total energy at each instant, and the directional change of the magnetic field lines on the two sides of the current sheet in the local maximum dissipation region. The second and fourth columns from the left represent the density (ρ), temperature , and vertical component of the velocity (U_z) in the vicinity of each SSHE’s local maximum at each instant. The different colored lines represent the variables in the 27 cells that correspond to the core region of the SSHE over time. The asterisks in these groups of panels correspond to the value of the variables in the local maximum locations of the SSHEs every 10 s during their lifetime.
