Extended Data Fig. 6: Seasonality of subsurface heatwave characteristics in the Great Lakes.

Characteristics are shown for heatwave events that span a single season (a1-d1) and two seasons (a2-d2). We show the seasonal variability in each of the lake heatwave characteristics, namely their (a) average occurrence, (b) average duration, (c) average intensity, and (d) average cumulative intensity. The values are the annual means during 1980-2022.
