Schematic diagrams for the circulation and rainfall (A) without and (B) with OGWD parameterization in the WRF model. Thin black vectors and thick green arrows denote horizontal wind fields and moisture transport, respectively. Blue arrows represent the mesoscale cyclonic circulation within the Sichuan Basin. Red arrows indicate the local anticyclonic circulation due to enhanced blocking high. The region of heavy rainfall is shaded in light gray.
