Number of summer heat wave days (HWs) (direct link to dataset not available)

Heat waves are defined as periods with at least 6 consecutive days where daily maximum temperature exceeds a given threshold during the summer period (June-July-August), set as the 90th percentile of daily maximum temperature for the baseline period (1986-2005). Heat wave days were computed for seven high-resolution (0.11°) regional climate model simulations from EURO-CORDEX and then averaged over the 2-year summer periods by calculating the multi-model-median values. The variability across the different model simulations is displayed through the interquartile range which is shown in the legend.
