Fig. 3: Meridional‒depth profiles of zonal-mean historical values and projected changes in subsurface marine heatwaves (SMHWs).
From: Intensification of future subsurface marine heatwaves in an eddy-resolving model
Historical values and projected changes in mean intensity (a, b, c) and annual days (d, e, f) of MHWs over the historical period (a, d), future changes based on the mean warming-inclusive threshold (b, e) and future threshold (c,f) from CESM-HR in the upper 1000 m of the Pacific, Atlantic, and Indian oceans. The solid horizontal lines in the panels divide the latitudinal ranges into tropical (black) and western boundary current and frontal regions (green). The dashed gray line represents a depth of 100 meters. Results show a general increase based on the future threshold for both the annual MHW days and mean MHW intensity.
