Fig. 5: Comparisons of water balance signals and supporting data.
From: Patterns and drivers of Holocene moisture variability in mid-latitude eastern North America
a Water balance synthesis curves (dotted lines; five-point running mean is indicated with a solid line) with 95% error margins (shaded bands) for the Midwest, Great Lakes, and Northeast regions, expressed as deviations from the preindustrial (0.25–0.75 ka) mean. The gray bar indicates the centennial event at 5.5–5.0 ka. b Centennial-scale variations in the Midwest, Great Lakes, and Northeast water-balance reconstructions, calculated as the residuals of LOESS smoothers with a 2-ka span (dashed lines in panel a). c–d Regional forcing factors including June insolation at 45°N78 (c) and Laurentide ice sheet (LIS) extent during deglaciation79 (d). The insolation values in panel (c) are overlain by sample values for PC1 of the water balance reconstructions, and the LIS extent in (d) is overlain by PC2 (dashed lines).
