Fig. 1: Deglacial evolution of East Asian monsoon in iTRACE and paleoclimate proxy.
From: Deglacial variability of South China hydroclimate heavily contributed by autumn rainfall
a Forcing: June insolation at 60°N (red), atmospheric CO2 concentration (green), and meltwater fluxes in the Northern Hemisphere (blue) and Southern Hemisphere (orange); b cave \({\delta }^{18}{O}_{c}\) in iTRACE (purple) and observation (black) at Hulu cave10; c South China [20–35°N, 108–120°E] summer (blue) and autumn (red) precipitation and the leading PC of Mg/Ca, Sr/Ca, and Ba/Ca records observed in Haozhu9, a proxy for South China monsoon precipitation (green); d EAWM index (blue) in iTRACE, SCS SST-gradient index (dots)13, and sediment Ti content (green) from Lake Huguang Maar4, proxies for EAWM; e simulated AMOC intensity (blue) and observed 231Pa/230Th in sediment core GGC5 as a proxy for AMOC intensity (black)11. In c, the ice sheet and ocean bathymetry effect is removed in autumn precipitation (see supplementary). In d the EAWM index is defined as region average [20–35°N, 108–130°E] of the near-surface (925-1000hPa) meridional wind. The SST gradient and EAWM index are normalized for presentation.
