Fig. 1: Annual trends for AHW and MHW intensities.
From: Mediterranean marine heatwaves intensify in the presence of concurrent atmospheric heatwaves

AHWs and MHWs (a) mean (Imean) and maximum intensity (Imax) mean values annual trend with linear regression (shadowed area shows the 95% confidence interval) and (b) regional distribution of Imean trend (dots show 99% statistically significant values). All plots show trends for the 1940–2022 period with reference period 1961–1990. A general positive trend is observed throughout the basin, being more intense for MHWs and especially for maximum intensity.
