What is it about?
Our study examines the significant atmospheric features that led to extreme weather events across Europe in early September 2023, highlighting the role of an omega blocking pattern producing heavy precipitation in Spain, dust outbreak from Sahara Desert, extreme precipitation in Greece, extreme precipitation in Libya, dust outbreak from Western Egyptian Desert, and heatwave conditions in Northern France and Britain.

Why is it important?
We show that although mesoscale conditions are relevant to formation and intensification of some atmospheric phenomena, the establishment of an omega blocking pattern in early September 2023 showed how large-scale atmospheric dynamics can produce abnormal weather conditions on a continental scale over several days.
Perspectives
This case study highlights the importance of synoptic conditions, namely the omega blocking pattern location for the occurrence of extreme precipitation events, dust outbreaks, and heatwave conditions.
