Fig. 3: Factors affecting snowmelt flood timing.
From: Warming leads to both earlier and later snowmelt floods over the past 70 years
a | Boxplot of Spearman’s correlation coefficient between snowmelt flood timing (tsf) and five key variables: onset of seasonal warming (tow), snowmelt rate, maximum snow water equivalent (SWEmax) timing, melt onset date, and SWEmax. The number above each box indicates the number of catchments where the correlation is statistically significant (p < 0.05, t-test), and the number within each box indicates the median value. b | Spatial distribution of dominant factors controlling tsf, revealed by comparing the correlation strengths between tsf and the five key variables. c–g | Spatial distribution of Spearman’s correlation coefficient between tsf and each of the five variables: (c), tow, (d), snowmelt rate, (e), SWEmax timing, (f), melt onset date, and (g), SWEmax, respectively. Source data is provided as a Source Data file.
