Map of the column-integrated water vapour (mass of water per cross-section area, colour scale) for the T1:T1e simulation (left). The following two plots show the change in water-vapour column content for ProC:T1e (middle) and Sun:T1e (right) with the equivalent water-vapour column content of T1:T1e if it were at the same temperature profile as ProC:T1e and Sun:T1e, respectively, at the same relative humidity as T1:T1e. The percentage is calculated from the total water-vapour content of the column. A positive difference (blue) indicates a moister column than the T1:T1e, removing the effect of temperature on moisture from the Clausius-Clapeyron relation. The sub-stellar point is located at (0°, 0°). The scale for ProC:T1e and Sun:T1e is different.
