Longitudinal variations (top) and global means (bottom) of the vertical enthalpy flux F_ℋ profiles for three exemplary HD 209458b-like models: 0.125Ω₀ (left), Ω₀ (middle), and 15Ω₀ (right). In the top row, we plot vertical enthalpy flux profiles at five different longitudes, ranging from the sub-stellar point to just west of the anti-stellar point, as well as the mean enthalpy flux profile. However, since the mean flux is significantly smaller than the local fluxes, we replot the mean profiles in the bottom row such as to better demonstrate the vertical variations in enthalpy transport.
