Fig. 6: Periodicities in proxy datasets and model simulations.
From: Patterns and drivers of Holocene moisture variability in mid-latitude eastern North America
Distribution of significant periodicities between 8.0 and 0.25 ka is shown for six high-resolution fossil pollen sequences from the (a) Midwest and (b) Northeast regions, and for the three transient model simulations in the (c) Midwest and (d) Northeast. The thin vertical lines mark significant periodicities found for either water balance (dotted line) or July temperature (dashed line), with the color identifying the fossil site or climate model. The thick black curves show kernel density estimates fitted to the significant periodicities found for water balance (dotted line), July temperature (dashed line), or both combined (solid line). All detected periodicities are presented in Supplementary Table 3, the wavelet power spectra of the individual reconstructions and simulations in Supplementary Figs. 18–25, and the mean power plots in Supplementary Fig. 26.
