(a) The precipitation distribution in the Tianshan region from 12:00 on July 31 to 12:00 on August 1, 2016 (shadow, unit: mm). (b) The geopotential height of 500 hPa (solid line; unit, dagpm), wind field (wind pole; unit, m·s−1), and high-altitude jet stream at 200 hPa at 12:00 on July 31, 2016 (shadow; unit, m·s−1) (the blue rectangle represents the location of the rainstorm area, the brown solid line represents the groove line, and the red solid line is the temperature groove line).
