Extended Data Fig. 5: CESM 1.2 annual cycle of equatorial Pacific SST under different combinations of tilt and distance effects.
From: Two annual cycles of the Pacific cold tongue under orbital precession

Plotted is climatological monthly mean SST averaged over 6°S–6°N across the Pacific. In all cases, LOP = 0°. To facilitate comparison, an offset is added to each panel so that the annual mean SST averaged over 145°E–85°W is the same as for the observational data as shown in Extended Data Fig. 1a, 27.44 °C. (a) e = 0.05, obliquity = 23.439° (tilt and distance run); (b) e = 0.05, obliquity = 0° (distance-only run); (c) e = 0.00, obliquity = 23.439° (tilt-only run); (d) sum of the annual cycles of (b) and (c), added to the annual mean of (a); and (e) e = 0, obliquity = 0° (zero annual forcing run).
