Fig. 3: Spatial trends of SEPHCE (sequential extreme precipitation–heatwave compound events) frequency in China from 1975 to 2020.
From: Unveiling the dynamics of sequential extreme precipitation-heatwave compounds in China
a Spatial trends of SEPHCE frequency at the 7-day interval; b spatial trends of SEPHCE frequency at the 5-day interval; c spatial trends of SEPHCE frequency at the 3-day interval; d spatial trends of SEPHCE frequency at the 1-day interval. The black squares show the variation trend was statistically significant at the 1% significance level.
