Fig. 4: SST tendency and atmosphere–sea heat-flux components during MHW onset.
From: Mediterranean summer marine heatwaves triggered by weaker winds under subtropical ridges
a, Composites of ESA CCI SST tendency for WMed. b, Equivalent SST tendency of total fluxes for WMed. c–f, Relative importance with respect to the SST tendency (a) of the four flux components from ERA5: latent (c), sensible (d), net long-wave radiation (e) and net short-wave radiation (f). Hatching in b identifies where the equivalent flux tendency explains more than 70% of the SST tendency in a. The anomalies are calculated against the full study period (1982–2022).
