Figure 9. Community Atmosphere Model version 5 DJF idealized uniform warming responses.

CAM5 (left) uniform SST warming; (centre) uniform warming with fixed tropical Pacific SSTs; and (right) tropical Pacific SST warming responses for (a–c) precipitation (mm day⁻¹); (d–f) U300 (m s⁻¹); (g–i) V300 (m s⁻¹); and (j–l) pp (hPa²). Symbols represent significance at the 90% (diamond), 95% (X) or 99% (+) confidence level, based on a t-test for the difference of means. Climatological U300, V300 and pp values are also included as thin black contour lines.
