Horizontal structure of stationary waves simulated by the Venus PCM, averaged over 5 Venus days. Panels show air temperatures (a), vertical winds (b), zonal winds (c), and meridional winds (d) at three altitude levels: deep atmosphere (−30 km), lower clouds (~50 km), and cloud top (~70 km). Black contours indicate the underlying surface topography, with elevations corresponding to major highland regions. Undulations on each horizontal slice represent the absolute values of anomalies scaled by two standard deviations (〈X〉′/2σ) to enhance visibility in the 3D perspective.
