Fig. 4: Attribution of changes in snowmelt flood timing.
From: Warming leads to both earlier and later snowmelt floods over the past 70 years
a–d | Histograms of trends in onset of seasonal warming (tow), snowmelt flood timing (tsf), the maximum snow water equivalent (SWEmax) and snowmelt rate in catchments with (a), advanced tsf and tow, (b) advanced tsf and delayed tow, c, delayed Tsf and advanced tow, and (d), delayed tsf and tow. The vertical dashed lines represent the mean trends. e | Spatial distribution of dominant factors contributing to earlier Tsf. f | Spatial distribution of dominant factors contributing to later Tsf. The number in parentheses indicates the number of catchments. Source data is provided as a Source Data file.
