H-15-150 simulation (α_lat = 15° and α_lon = 150°). Top: Comparative maps showing the reconstructed topography from the first five spherical harmonic orders of altitude and the quadrupolar pressure anomaly at various times of day. The topography is displayed as the colored background, while the pressure anomaly is indicated by red (positive) and blue (negative) contours. Bottom: Atmospheric thermal torque as function of the subsolar point longitude. The dotted red lines indicate the longitude of the subsolar point for the six maps presented in the top panel. Letter A-E indicate the locations of the principal provinces of Venus, as defined in the caption of Fig. 1.
