Fig. 2: Annual frequency and trend of AHW and MHW events by concurrence type.
From: Mediterranean marine heatwaves intensify in the presence of concurrent atmospheric heatwaves

Annual number of AHW (May–September) and MHW (all year) events by concurrency type for the Mediterranean and its different subregions (ASEA = Adriatic Sea, WMED = Western Mediterranean, and ESEA = Eastern Mediterranean). Points size denotes event duration. Concurrent events show an increase for AHWs while MHW concurrent events also increased their frequency and duration.
