Short summary

This study investigates the intense heatwaves of 2022 in the Pyrenees. The interplay of the synoptic circulation with the complex topography and the pre-existing soil moisture deficits played an important role in driving the spatial variability of their temperature anomalies. Moreover, human-driven climate change has made these heatwaves more severe compared to the past. This research helps us better understand how climate change affects extreme weather in mountainous regions.
