In this paper, a sever hail event happened in central Shandong province on June 14, 2016 was analyzed based on the conventional observations, sounding data of Zhangqiu station and new generation SA weather radar detections in Binzhou and Jinan. The results show that: The significant increase of atmospheric unstable energy and the strong vertical wind shear are the favorable environmental conditions for generation of strong convection. The longlived hail monomer moved along the valley between two mountains, which played an important role in air mass uplifting, monomer sustaining, and monomer track leading. The VIL (vertically integrated liquid) leap before the occurrence of thunderstorm is favorable to the formation and growth of hail particles. The long TBSS (three body scatter signature), deep and persistent mesocyclone, overhanging strong reflectivity center, bounded weak echo regions and strong divergence at the top of the storm are significant characteristics of this strong hail event.
