Extended Data Fig. 4: Modelled summer precipitation rate (JJA, mm yr−1) in isoCAM simulations.
From: Decadal warming events extended into central North America during the last glacial period
Plotted are modelled precipitation rate during GI (middle), GS (bottom) and the differences (GI minus GS, top). The simulated increase of the precipitation at COM originates from both Eastern Tropical Pacific and Gulf of Mexico, and therefore bring more positive δ18O from tropics to COM.
