摘要

Based on conventional observation data and MICAPS data,disaster characteristics,circulation situation and dynamic mechanism of heavy rainstorm process during June 22-23,2019 were analyzed.The analysis showed that dynamic mechanism of the heavy rainstorm was 200 hPa of high-pressure divergence area,high-altitude shallow trough,850 hPa of low-level shear line and ground cold front.The radar echo showed that the"train effect"of strong banded echo caused a continuous heavy rainstorm.
