Two scenarios with the least (SSP245COOLER_NEAR) and most (SSP585HOTTER_FAR) impacts are shown here as examples. Basins are divided into six regions for the regional analysis. a1–d1 Warming impacts on mean air temperature and annual precipitation. a2–d2 Warming impacts on MD characteristics (total duration and mean severity). a3–d3 Warming impacts on AD characteristics. a4–d4 Warming impacts on HD characteristics. Note that the air temperature and precipitation changes shown are mean annual values; seasonal patterns can differ significantly. For example, in the SW, projections indicate wetter winters and drier summers. See Supplementary Figs. 2–5 for seasonal air temperature and precipitation changes.
