摘　　要：2016年6月22—23日南昌市出现了全市范围的暴雨、大暴雨天气,造成了严重的积涝、内涝。利用天气实况、区域自动站资料以及NCEP 1°×1°再分析资料,对6月22日南昌市大暴雨天气过程的物理量进行诊断分析,着重根据此次过程的时空分布特征进行研究,得出结论:(1)此次过程主要受高空槽东移、中低层西南气流以及低层切变共同影响;(2)充足的水汽条件、能量条件以及垂直运动条件均有利于触发暴雨;(3)在高空槽东移、西南气流以及切变线共同影响的环流背景下,南昌地区整层湿度较大,地面辐合线及倒槽位于南昌附近,有利于南昌成为强降水中心。From June 22 to 23,2016,rainstorm and heavy rainstorm occurred in Nanchang,causing serious overwork and waterlogging.In this paper,the physical quantities of the heavy rainstorm weather process in Nanchang on June 22 were diagnosed and analyzed by using the weather reality,regional automatic station data and NCEP 1°×1° reanalysis data,focusing on the spatial-temporal distribution characteristics of this process,and the conclusions were drawn:(1) This process was mainly affected by the eastward movement of the high trough,the southwest airflow in the middle and low levels,and the shear in the low levels;(2)Sufficient water vapor conditions,energy condition and vertical motion conditions were conducive to triggering the rainstorm;(3) Under the background of circulation influenced by the eastward movement of the high altitude trough,southwest airflow,and shear line,the overall humidity in the Nanchang area was relatively high,and the ground convergence line and inverted trough were located near Nanchang,which was conducive to Nanchang becoming a center of heavy precipitation.
