Short summary

This paper presents a study of extremely hot days (EHDs) in Spain and their connection with atmospheric dynamics. In addition, this work proposes a method that allows the detection of trends in the frequency of extreme events and their attribution to changes in atmospheric dynamics characterized through circulation types (CTs). The main CT-driven EHDs are identified. The increase in the EHD appearance is linked to the increase of the extreme CTs; however this only partially explains the trends.
