Future summer mega-heatwave and record-breaking temperatures in a warmer France climate

Description

The focus of this study was on future very hot summers associated with more severe heatwaves and record-breaking temperatures in France. Historical data of daily temperature observation and future scenarios (RCP 8.5) served as an input for a simulation with a regional climate model (ALADIN). It shows the spatial distribution of extreme events (heatwaves) and their evolution till 2100.

Results show that a record maximum value could exceed 50 °C by the end of the 21st century in France. These temperatures are experienced in desert regions and it needs to be further studied how realistic these simulations are, considering vegetation and other factors that control the heatwave magnitude.
