| 英文摘要 | Understanding how atmospheric moisture pathways regulate precipitation variability is essential for basin-scale water security under climate change. Here we present a global, intensity-stratified analysis of moisture sources and transport across seven major river basins using ERA5 reanalysis and the WAM-2layers model. By combining precipitationshed diagnostics with empirical orthogonal function analysis, we identify dominant and higher-order moisture transport modes and assess their roles in seasonal and extreme precipitation. River basins are classified into ocean-dominated, mixed-source, and land-dominated regimes based on the structure and variability of moisture transport. Ocean-dominated basins exhibit coherent moisture pathways and strong coupling between precipitation and the leading transport mode, whereas land-dominated and high-latitude basins show weaker coupling and a greater reliance on higher-order modes, particularly during seasonal transitions and heavy precipitation events. Mixed-source basins maintain robust precipitation-transport relationships despite pronounced seasonal shifts. We further identify regime-dependent multi-decadal shifts in moisture source regions and seasonally varying climate influences on transport modes, demonstrating that mean moisture source fractions alone cannot explain precipitation variability and extremes. These findings improve our understanding of basin-specific hydroclimatic responses and offer valuable insights for future hydrological predictions and climate adaptation. |
