Fig. 9: Changes in background clouds.

Horizontal maps of ensemble-averaged changes in DJF background a–c total cloudiness (shading, unit: %); d–f high cloudiness (shading, unit: %); g–i middle cloudiness (shading, unit: %); and j–l low cloudiness (shading, unit: %) in three selected time slices in the CESM1.2 model. The Δ symbol indicates the ensemble-average change relative to the control simulation ensemble average. Stippled areas denote changes exceeding the 95% confidence level.
