Fig. 3: Comparsion of the EAWM variability with the prehistorical cultural development in the CEC.

Detrended SST in Core SD-01 represented by 250–700 a band-pass filter of the detrended SST (A), density cultural 14C probability (B), and RGR (C) in central plain and eastern China represented by 200–1000 a band-pass filter of the detrended RGR.
