Same as Figure 2, but for the mechanism-suppression experiments. (a), (e) show the 80° obliquity experiment with fixed surface temperature which is the annual mean surface temperature in the default experiment. The experiment setups in (b), (f) are the same as (a), (e), except that the surface temperature distribution is flipped over about 45° north/south. (c), (g) show the fixed-SST zero-obliquity experiment without equatorial cold trap. (d), (h) show the 80° obliquity experiment forced by annually averaged insolation.
