Atmospheric aerosol particles affect the formation of precipitation through influencing on microphysical properties of water and ice clouds. In early May of 2018, we observed the coincident of strong dust and rain events in the Nile Delta area. We also used Hybrid-Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model, NMMB/BSC-dust model and NOAA-18 Cloud Height product to validate this same movement of dust and clouds that induced precipitation. In addition, Niño 3.4 index with historical rain and dust anomalous events during 1980–2017 were analyzed to reveal the relationship between these events and global climate system. The results revealed an obvious matching in both intensity and movement for both dust and precipitation events in early May 2018. Extreme precipitation anomalies during 1990–1999 occurred in company with positive Niño indices and less dust events.
