利用NCEP再分析资料、常规观测资料、区域气象观测站资料和多普勒天气雷达资料等，对2016年6月13—14日山东强对流天气过程的中尺度特征、触发条件及雷达回波等进行了分析。结果表明，冷涡前部高空槽和地面气旋造成13日强对流天气，高空冷涡和地面气旋造成14日强对流天气。高空干冷、低层暖湿气流有利于大气对流不稳定度加大。13日对流系统由2个独立的MαCS组成，14日则是由MβCS演变而成的MαCS系统。辐合线和干线是强对流天气的触发条件，两者重合处能诱发对流单体强烈发展。移动路径右偏中层引导风向、高空西北风的切入和地形因素是导致强降雹超级单体发展及持续存在的原因。6 h前的400～1 200 J·kg-1对流有效位能区域与降水落区对应较好。两日强对流天气过程的水汽均以西南向输入、南北向辐合为主；14日过程中渤海湾的水汽输送也很重要。高层更宽阔的MPV异常及显著下传、高低层正负位涡差的增大会造成更强的上升运动和对流不稳定。
The mesoscale features, triggering conditions and radar echoes of strong convective weather processes occurred in Shandong from 13 to 14 June 2016 are analyzed by using the NCEP reanalysis data, conventional observation data, regional automatic station data and Doppler weather radar data. Results show that the upper trough in front of cold vortex and ground cyclones cause the convective weather on 13 June. The upper cold vortex and ground cyclones lead to the convective weather on 14 June. High-level dry cold air and low-level warm air flow are conducive to the increase of convection instability. The convection system(MαCS) is composed of two MαCSs on 13 June and the convection system(MαCS) is evolved from MβCS on 14 June. The convergence line and dry line are the trigger conditions of strong convective weathers, and the strong development of convective cells can be induced where they overlap. The right deflection of high-level wind moving path, the invasion in of upper northwest wind and the topographic factor are the reason of the development and persistent existence of supercell thunderstorms. The precipitation area has a good corresponding to the area with CAPE(convective available potential energy) of 400-1 200 J·kg-1 before 6 h. The water vapor is dominated by the southwest input and the north-south convergence during the strong convective weather processes on 13 and 14 June. Besides, the moisture transport from Bohai Bay is also important for the weather process on 14 June. The wider MPV anomaly at the upper level and its significant downward transmission, and the increase of positive and negative vorticity difference at high and low levels can cause stronger ascending motion and convective instability.
