Simulated difference in the mean annual maximum number of consecutive days with a maximum temperature greater than 95F

Simulated difference in the mean annual maximum number of consecutive days with a maximum temperature greater than 95F (Tmax > 95F) 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 consecutive days. Color with hatching (category 3) indicates that more than 50% of the models show a statistically significant change in the number of consecutive days, and more than 67% agree on the sign of the change (see text). Mean annual maximum number of consecutive days with Tmax > 95F for the 1980-2000 reference period (bottom left). Simulated mean annual maximum number of consecutive days with Tmax > 95F 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. Note that top and bottom color scales are different. Increases are largest in the southeastern portion of the region.
