Temperature evolution for the 225 simulations of the rain bow using the geometry S47 (stereoscopically reconstructed shape, with a maximum area expansion A_max = 47), a constant heating rate H₀ = 15.5 μW m⁻³, and a stratified heating rate H₁ = 2560H₀ = 39.7 μW m⁻³. (a) Overview of the simulations performed with λ₁ and λ₂ each varying from 1% to 20% of the loop length L. Each sub-plot shows the evolution of temperature as a function of the position along the loop s (x-axis, ranging from 0 to L = 635.36 Mm) and of time (y-axis, ranging from 0 to 72 h). Event types are marked by coloured squares: TNE cycles with no coronal rain (), cycles with rain (), and prominence-like structures (). The white dashed line corresponds to λ₁ = λ₂. (b) Sample simulation showing TNE cycles without coronal rain. (c) Sample simulation showing TNE cycles with coronal rain. (d) Sample simulation showing the formation of a prominence-like structure.
