Distribution of interface magnetic curvature values for our sample of M_cl ∼ 10⁶ M_⊙ clouds (main panel). The black curve is based on all interface gas, while the other curves show values derived using gas with different relative positions with respect to the direction of motion of the cloud. The purple curves show κ for the head or upstream regions, while the yellow curves show κ in the tail or downstream regions. The inset compares the upstream interface magnetic curvature from our simulations (κ_GIBLE) to a simple theoretical model (κ_DP08).
