a,b, Boreal summer (JAS) SST (shading), air pressure at surface (PS, shading) and 850-hPa wind (vector) anomalies at Pmin from transient experiment CESM_ghg. c, JAS δ18Op differences between Pmin and Pmax from two equilibrium experiments of iCESM (Pmin minus Pmax)36. d–i, Outputs from transient experiment GISS_ghg, including JAS SST (d), PS & 850 hPa wind (e), evaporated vapour δ18O (δ18Oevap) (f), precipitation (g), vertical integrated atmospheric vapour content (h), and evaporation (i). Except for c, white shading denotes areas not significant at 95% confidence level of two-tail t-test. These patterns are shown as regression coefficients against the normalized time series of precession parameter, which are multiplied by −1 to demonstrate the effect of Pmin relative to Pmax. Yellow and black boxes are used to define those time series of IPWP (5°S-15°N, 140°E-170°E) and of East Asia (15°N-40°N, 85°E-125°E) in Extended Data Fig. 8, respectively.
