the terminator profiles. We also show the dayside (red dash-dot) and the nightside (blue dash-dot) averages which are poor representations of the day- and the nightside temperature distributions, respectively.

The inspection of the equatorial temperature distribution (Fig. \[TpNuc\] bottom left) suggests a west-east asymmetry with the east ($\phi\rightarrow 90^o$ ) being warmer than the westerly ($\phi\rightarrow 270^o$) dayside. The day-night temperature difference can clearly be seen from this 2D plots, and the changing temperature throughout the whole terminator regions that is probed by transmission spectroscopy is best seen in Fig. \[TpNuc\] (middle left).

Setting the JWST target WASP-43b in perspective, we further demonstrate that, within the uncertainty of the GCM temperature structures, WASP-43b’s day- and nightside are on average cooler than those of a ultra-hot Jupiter like WASP-18b (Fig. \[TpDP\]). We also note that the vertical extension of the GCM profiles fall short of what 1D atmosphere simulations can provide by comparing to our 1D [Drift-Phoenix]{} model (Fig. \[TpDP\], solid gray lines). [@2019arXiv190413334C] have demonstrated the effect of the inner boundary on the flow regimes in the atmosphere of WASP-43b. This has substantial impact also on the local thermodynamic conditions inside the atmosphere and we will need to return to
