Left panels: convective flux in units of total flux, root mean square vertical velocity in units of km s−1, and dissipation rate ϵ from Eq. (11) relative to a value computed from Eqs. (5) and (6) with α as given in the figure legend. Right panels: same quantities as left panels, however, the downgradient approximation (DGA) is used to compute third order moments instead of the full model used in Kupka & Montgomery (2002). The results are for one of the A-star envelope models discussed in Kupka & Montgomery (2002).
