Contributions of (absolute) individual terms to the total lhs.

TKE (ω)		Convective flux (Π)		Entropy fluctuations (Φ)
Term	Contrib (%)	Term	Contrib (%)	Term	Contrib (%)
non-local	29.6	non-local	8.7	non-local	33.0
buoyancy	56.4	buoyancy	27.8	potential	66.9
shear	4 × 10⁻³	potential	26	radiation	6 × 10⁻²
pressure fluc	14.2	radiation	2 × 10⁻³	nuclear	9 × 10⁻⁴
		shear	7 × 10⁻⁶
		nuclear	1 × 10⁻⁴
		pressure fluc	37.6

Notes. Total contributions of the absolute values of the individual terms integrated over the convective region defined by the TKE boundary. The values are time averaged over five τ_conv in the sim_k simulation. The radial dependency can be seen in Figs. F.1–F.3.
