Characteristic of Radar Echo for a Severe Convective Weather in Shiyan, Hubei Province

By using the 714C radar echo data in Shiyan and other weather data, a severe convective weather event in Shiyan on 6, July 2004 is analyzed. The result shows that the severe convective storm occurred under the advantageous large scale weather conditions, with local large CAPE index and strong vertical shear of horizontal wind. Severe hail is caused by multicell severe storm. It has the intensive radar echo, high cloud top, affectation echo on the cloud top caused by radar sidelobe and weak echo region in the lower layer. Hail cloud moves in the right side of the high level wind with right-behind or right-forward propagation. Severe hail is caused by the second propagation, the original echo occurs in the high layer. The cloud top is high and the center of echo locates in the high and middle layer of cloud.
