Surface boundary configurations used in this study. Middle column: map view of continental distribution and topography with the substellar point centered at 0° longitude, or on the dayside. Left column: identical surface realizations centered on the nightside. Right column: corresponding three-dimensional renderings of the topography. Rows show (top) Baseline flat continent, (middle) Steep Uplift, and (bottom) Dayside Plateau. The mean elevation is comparable in the bottom two cases.
