Figure 3

The proxy record of summer rainfall in eastern-Central Asia inferred from δ13C of Chaiwobu peat cellulose (c) and its comparison with related proxy climate records. The orange triangles show the calibrated 14C age-control points of the Chaiwobu time series. (a) The drift ice record of the North Atlantic. The numbers from 1 to 5 indicate the five ice-rafted debris (IRD) events of the North Atlantic27. (b) The proxy temperature record from δ18O of the Hani peat cellulose29. (d) The proxy record of the East Asian summer monsoon from δ13C of the Hani peat cellulose23. (e) The proxy record of the Indian summer monsoon from δ13C of the Hongyuan peat cellulose21. (f) The climate index of the westerlies from the flux of the >25 μm fraction in the Lake Qinghai sediments7. The grey curve shows the solar radiation difference between March and September at the equator as a measure of seasonality in the cold tongue of the eastern Equatorial Pacific45. The grey bars trace the teleconnection between the summer rainfall in eastern-Central Asia, the Asian monsoon, the westerlies, and the air temperature.
