Abstract:
The evolutionary trends of storm cells in three severe weather events occurred in 2005 and 2006 in Shandong Province are analyzed by means of CINRAD/SA data from the Jinan radar station. The results indicate that there appeared synchronous increase in cellbased CVIL and maximumreflectivity heights in some severe storm cells before hailing on the ground, with the height being 6 km or higher and CVIL being over 18 kg/m2; and there appeared synchronous decrease before violent surface wind occurring with the height being 2 km or lower and CVIL being at least 10 kg/m2. The lead time of 7 to 20 minutes for hailwarning and that of 0 to 9 minutes for violent surface wind warning are obtained.
