Short summary
Atmospheric rivers, narrow and long corridors of intense horizontal moisture transport, may produce heavy precipitation where they are forced to rise over the orography. This has been recently shown to occur also in the Mediterranean basin, especially over the Alps and Apennines in Italy. The present study analyses the presence of atmospheric rivers in this area, in the period 1961–2024, and reveals a strong connection with extreme rainfall over northern-central Italy.
