Short summary
This work presents the identification of Saharan warm-air intrusions in the western Mediterranean, which are the displacement of air masses formed over the Sahara toward the west of the Mediterranean region. We focus on the recent past and obtain a catalogue of intrusion days. The results show the existence of different types of intrusions, important impacts on extremely high temperatures in the Mediterranean and Europe, and the dynamic mechanisms that can cause the onset of these events.
