a Correlation of boreal summer-averaged daily maximum temperature in central-eastern China based on the Berkeley Earth data with that measured data from the Xujiahui Meteorological Observatory in Shanghai. The blue outline indicates the area of Central-eastern China (20°–40°N, 90°–120°E) in this study. b Sequences of the 11-year smoothed mean CECSH (yellow line; days), and detrended AMOCORE (green line; °C), WPSST (blue line; °C) anomalies in the boreal summer during the period 1900–2019. Correlation of boreal summer extreme heat days in central-eastern China with the detrended boreal summer c AMOCORE and d WPSST anomalies after 11-year smoothed mean during the period 1900–2019. The black dot indicates the correlation coefficient above the 95% confidence interval based on effective degrees of freedom.
