Figure 1.Mean warm-season MHW properties over the 1985-2014 period. (a-d) the mean duration of the continuous warm-season MHW (Dc, day); (e-h) the mean annual peak HS (HSpeak, °C); (i-l) the mean accumulated heat stress of the continuous warm-season MHW (Ac, °C·day). The mean states from the first to last rows correspond to the properties observed and simulated by GFDL-ESM4, CESM2-WACCM and MRI-ESM2, respectively.
