Meridional cross section of specific humidity (upper panels) and temperature (lower panels). Shown are 12 month averages in the transient simulations, centered at 1750 W m⁻² insolation forcing. (a), (d) for zero obliquity, (b), (e) for 80° obliquity annual mean, and (c), (f) for 80° obliquity February. Climatology in simulations with fixed 1750 W m⁻² insolation resembles the approximation given by the transient simulations (not shown), indicating that the climate is fairly close to the equilibrium.
