Understanding extreme precipitation event (EPE) propagation is crucial for hazard early warning. This study uses climate networks based on event synchronization to analyze global EPE propagation patterns, identifying 16 major pathways linked to regional weather systems, topography, and Rossby waves. The study demonstrates substantial EPE predictability in certain areas (e.g., Appalachians, Andes) and highlights the power of climate network approaches for studying extreme event connectivity.
