Global wind velocity streamlines for the three topographic configurations. The black streamlines show the time-mean horizontal flow at 100 hPa, with line width proportional to wind speed (see the scale bar). The red contours outline the 273 K temperature curve. The panels show the Baseline (left), Steep Uplift (center), and Plateau (right) cases. In this regime, the Steep Uplift and Plateau cases exhibit intensified stationary waves and cross-terminator flow, while the Baseline yields a more zonally symmetric and weaker circulation.
