Analysis of Severe Convection Process in Weifang, Shandong Province

Based on the data from Qihe Doppler radar, Weifang radar and automatic meteorological stations, an analysis of severe convection event in Weifang, Shandon Province on May 19,2003 is made. The results show that the eastwards quick moving transversal trough and its train cold wave strengthened the instability, while, low-layer warm and wet current provided dynamical and water vapor condition for its development.
