摘要：Four consecutive days of rainstorm happened in the eastern part of the Qinghai-Tibet Plateau from 08:00 on July 24 to 08:00 on July 27,2017,and the high-altitude circulation situation,sounding data,ground station data,physical quantity field,and satellite cloud picture were analyzed.It is concluded that the triggering environment of this rainstorm weather was formed under the common effect of the stable restriction of the confrontational weather scale of the Western Pacific subtropical high and the Middle East continental high,and the continuous forced disturbance of the wide low-value area over Eurasia;the indicators of water vapor,unstable energy,and upward movement in Qinghai Province had certain indications on whether heavy precipitation will be triggered;meanwhile,the special topography of the Hehuang valley in the east played an important role in the triggering of local heavy precipitation.
