The 500 hPa GPHs (red contours; unit: gpm) and wind (black vectors; unit: m/s) from ERA-Interim reanalysis data and gauge-based precipitation data (green contours for 10 mm and blue contours for 50 mm) in forecast for next 90–108 h (4-time average, 1800 UTC 17 July–1200 UTC 18 July) after the initial time of 0000 UTC 14 July 2013. (a) Composite of six stronger members with the lowest values of TPMVI. (b) Composite of six members with the highest values of TPMVI. (c) Difference by six stronger members minus six weaker members. The blue rectangle indicates the Sichuan Province. The shaded areas show the terrain elevations (shaded every 1000 m) in eastern Eurasia.
