Projected Change in Mean Annual Precipitation; 2041-2070 relative to 1971-2000
Projected change in mean annual precipitation (%) for the contiguous United States, for 2041–2070 with respect to the reference period of 1971–2000. These are multi-model means using CMIP3 SRES A2, A1B, and B1 scenarios (left column), and CMIP5 RCP8.5, 6.0, 4.5, and 2.6 scenarios (right column). Color only (category 1) indicates that less than 50% of the models show a statistically significant change. Whited out areas (category 2) indicate that more than 50% of the models show a statistically significant change, but less than 67% agree of the sign of the change. Color with hatching (category 3) indicates that more than 50% of the models show a statistically significant change, and more than 67% agree on the sign of the change (see Section 3).
