Fig. 2: Subsurface evolution of lake heatwaves.
a–d, The vertical variability of each lake heatwave metric from 1980 to 2022, with the central line representing the median and the shaded region representing the median absolute deviation (MAD). Shown as the vertical profiles of total heatwave days (a), average heatwave duration (b), average heatwave intensity (c) and heatwave cumulative intensity (d). e–h, The interannual variability in each lake heatwave metric at different depths (negative depths are below the lake surface), showing the changes with depth in total heatwave days (e), average heatwave duration (f), average heatwave intensity (g) and heatwave cumulative intensity (h). Here we compare only the vertical profiles of each heatwave metric across lakes that are shallower or equal to 10 m.
