Simulated Number of Days with Tmin
Simulated multi-model mean change in the mean annual number of days with a minimum temperature less than 0°C (Tmin < 0°C) for the contiguous United States, for 2046–2065 with respect to the reference period of 1981–2000, using the CLIMDEX RCP8.5 scenario (top). Color only (category 1) indicates that less than 50% of the models show a statistically significant 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).
