General Information

Simulated percentage difference in the mean annual number of days with precipitation of greater than 0.3 inches for the Northwest region, for the 2041-2070 time period with respect to the reference period of 1980-2000 (top). Color only (category 1) indicates that less than 50% of the models show a statistically significant change in the number of days. Color with hatching (category 3) indicates that more than 50% of the models show a statistically significant change in the number of days, and more than 67% agree on the sign of the change (see text). Mean annual number of days with precipitation of greater than 0.3 inches for the 1980-2000 reference period (bottom left). Simulated mean annual number of days with precipitation of greater than 0.3 inches for the 2041-2070 future time period (bottom right). These are multi-model means from 8 NARCCAP regional climate simulations for the high (A2) emissions scenario. The models simulated increases for the central part of the region, with the greatest increases occurring in southeastern Oregon. There are simulated decreases in the southwestern part of the region and in central Idaho.
