efficiently, SiO nucleation is terminated and seeds form more efficiently in the middle atmosphere at $\approx 1$bar. KCl seeds do form on the night side in the low-pressure atmosphere but with a rate that is too low to be significant (Fig. \[fig:NucRateDayNight\])

Asymmetric cloud coverage and non-homogeneous cloud properties
--------------------------------------------------------------

The equatorial cut (Fig. \[TpNuc\], middle right) shows the day-night and west-east ($\phi=270^o\rightarrow 90^o$) asymmetry in the formation rate of condensation seeds in the atmosphere of WASP-43b. The equatorial asymmetry in the seed formation rate is less strong (Fig. \[TpNuc\], bottom). Based on the present 1D profiles, the eastern dayside of WASP-43b ($\phi=0^o\rightarrow 90^o$) forms condensation seeds in a narrow range at p$_{\rm gas}<10^{-4}$bar. The western dayside ($\phi=0^o\rightarrow 270^o$) features a wider seed formation zone compared to the eastern dayside which deepens with increasing longitude $\phi$ in the equatorial region of WASP-43b.
