Abstract This paper uses conventional meteorological data,Hefei S-band Doppler weather radar and Wuhu X-band phased array weather radar data to analyze the 2022-06-05 rainstorm process in Wuhu.The results show that:there is an obvious warm and wet air flow transport on the south side of the middle and low level shear line,and the cold and warm air flow convergence makes the ground convergence line maintain in Wuhu area for a long time,forming the short-term heavy rainstorm.The X-band phased array radar has high detection accuracy,and the three-dimensional inverted wind field can reflect the dynamic structure of small and medium-sized convective storms.During this process,the X-band phased array radar observed that the wind field in the middle layer of Yijiang District,Wuhu,had obvious convergence and rise,which made the storm move here and strengthen its development,forming the "train effect",which was the dynamic reason for the rainstorm here.
