Abstract:
Based on the conventional and non-conventional observation data,the squall event occurring on June 7,2004 in Hengshui of Hebei Province is analyzed.The results show that the low vortex shear line and the cold front are the synoptic systems that caused the squall event.A cloud line is constructed by several convective cloud clusters on the cloud picture.The typical bow echo and adverse wind regions appeared on the map of Doppler radar reflectivity and velocity.By analyzing the cloud picture,lightning location data and Doppler radar echo,a conclusion can be drawn that the three kinds of non-conventional observation data have close relationship to the influence time,change of intensity and moving direction of synoptic system.
