Figure 4 Spatial patterns of droughts and floods in eastern China in cold and warm periods over a centennial scale (Hao et al., 2016). (a) Ensemble mean for all five cold periods (AD 440-540, 780-920, 1390-1460, 1600-1700, 1800-1900). (b) Ensemble mean for all four warm periods (AD 650-750, 1000-1100, 1190-1290, 1900-2000). (c) Difference between warm and cold periods (warm minus cold). The shaded area is the 90% significance level based on a chi-square test.
