The scale of photospheric convection in red giants is generally associated, by analogy with the Sun, with the atmospheric pressure scale height and the thickness of the superadiabatic transition layer(SAL). As pointed out by Schwarzschild(1975), both of these quantities are relatively much larger in terms of the stellar radius in a red giant then in the Sun. (omitted)
