Extended Data Fig. 1: Relationships of precipitation and δ18Op in East Asia with SST and upper OHC of the IPWP over 1970–2010.

a, Sea surface temperature anomaly (SSTA) of the annual mean ERSST (V4)86. b, Annual mean OHC anomaly above 20 °C isotherm depth over IPWP (15°S-15°N, 110°E-160°W), calculated from the SODA reanalysis dataset63. c,d, Annual mean anomalies of East Asian precipitation (black, d) and associated δ18Op (blue, c) (15°N-40°N, 85°E-125°E), based on the SWING2 GISS historical nudged simulation (over the years ~1970–2008)85. Time series in a–d are calculated by subtracting the temporal average of each variable. Vertical bars indicate the major periods of global warming hiatus. Dashed thick lines are long-term trends of 3-order polynomial fitting. e, Modern La Niña-associated annual mean OHC anomalies above 20 °C isotherm depth from SODA dataset, shown as regression coefficients against normalized time series of Southern Oscillation Index87 (SOI, grey line in b). f, As in e, but for La Niña-associated annual mean precipitation changes from the GISS historical simulation.
