Longitudinally averaged gas temperature [K] (left) and particle number density (right) for the standard HD 209458 b model at the end of the transparent cloud stage at t_cloud = 50 days (see Table 1 and Sect. 2.6) and the radiatively active stage at t_cloud = 100 days. For each time, three profiles are plotted that cover latitudes of ϕ = 0° (black), ϕ = 45° (blue), and ϕ = 90° (red).
