Modeling analysis reveals distinct moisture sources for cold vortex rainstorms in Northeast China, suggesting regional uptake patterns govern precipitation distribution.
Key Points
Moisture sources for northeast cold vortex rainstorms differ markedly between northern and southern centers, with regional uptake determining precipitation distribution.
East-central China provides 45.16% of moisture to the southern center, while Northeast Asia contributes 35.66% to the northern northeast cold vortex rainstorm center.
