Fig. 1: Annual variations of SEPHCE (sequential extreme precipitation–heatwave compound events) frequencies in China from 1975 to 2020.
From: Unveiling the dynamics of sequential extreme precipitation-heatwave compounds in China
a The annual SEPHCE frequencies; b the ratios of the mean SEPHCE frequencies in the latter 10 years to the former 10 years. Due to data limitations, the last mean ratio only takes into account the average from 2015 to 2020.
