Time-averaged total (black dash-dotted), convective (black), enthalpy (blue), radiative (dark purple), kinetic energy (light purple), and cooling (green) fluxes from Runs S7 (solid) and S7m (dashed). The vertical dotted lines indicate the bottoms of the buoyancy (BZ) and Deardorff zones (DZ). The bottom of the overshoot zone (OZ) for Run S7 (S7m) is denoted by the dashed (dot-dashed) vertical line.
