Fig. 4: The intensities of hot extremes associated with similar heat domes increase faster than global mean temperature.

a The distribution of the maximum temperature anomalies (detrend, unit: °C) for flow analog days (analogs, unshaded) generated using eddy geopotential height anomalies at 500 hPa from 27 June–3 July and randomly picked days (control, shaded) for ERA5 reanalysis and CESM1 simulations. b The distribution of the maximum temperature anomalies (unit: °C) for flow analog days in given levels of projected global warming. The black line corresponds to ∆Tmax = ∆Tmean, indicating the increase in extreme temperature is equal to global mean temperature. The red line indicates the maximum temperature anomalies of the average of 27 June–3 July 2021 from ERA5 in both figures.
