Fig. 5: Vertical distribution of surface‒subsurface compound marine heatwaves (MHWs) and proportion of single-layer MHW events involved in compound events.
From: Intensification of future subsurface marine heatwaves in an eddy-resolving model
Spatial distributions of the vertical extended depth of surface‒subsurface compound MHWs (a) in the historical period and the future change (2071‒2100 minus 1993‒2020) based on (c) the future threshold. Note that the color-bar range is different in each plot. The box-and-whisker panels (b, d) depict the proportion of SMHWs that are compound MHW events at different depths for (b) the historical period and the future change using (d) the future threshold, with the minimum and maximum (line endpoints), 25th and 75th percentiles (boxes), medians (horizontal lines), and averages (gray triangles) marked. The gray dots on right-hand side of panels (b, d) represent the proportion of SMHWs in each layer that does not occur synchronously with surface MHWs.
