(a) Pacific-Japan (PJ) teleconnection patterns in JA from 1979 to 2017 (shadings) (b) JA precipitation (shadings, units: m·day−1) regressed on the corresponding PJ index. Red and blue contour lines indicate positive and negative anomalies of (a) 850 hPa relative vorticity (units: 10−6 s−1) and (b) 500 hPa height (units: gpm) generated by COM experiment on day 15. Dark (light) stippling indicates values significantly exceeding the 99% (90%) confidence level using Student’s t test; the variance fraction explained by EOF1 is denoted at the top-right corner in (a).
