Fig. 6: Greater SSI values occurred under relatively cool and wet conditions, with low spring precipitation fractions.

a–d VIC-forcing average air temperature anomaly (horizontal axis) versus average precipitation anomaly (vertical axis), averaged by SSI anomaly percentile across the entire study area, and for the fall (SON), winter (DJF), and spring (MAM) seasons, respectively. Panels e–g show the average SSI value per SSI anomaly percentile bin (horizontal axis) versus the fraction of annual precipitation occurring within the fall, winter, and spring seasons, respectively, also across the entire study area. All data points are colored by the respective SSI anomaly percentile bin with larger SSI anomalies in blue and lower SSI anomalies in red. Each gray line represents the respective average temperature and precipitation anomaly values, and precipitation fraction and SSI values per individual ecoregion also grouped by SSI anomaly percentile bin.
