Abstract:
The severe convective predictive equation is set up with the method of stepwise discrimination analysis by using the TBB data from 2005 to 2008，to decide if a cloud cluster in the monitoring area will produce regional severe weather with the indicator superposition method. Based on the statistics of radar parameters during hail and gust events with thunderstorms for many years in Fujian， the radar parameter thresholds for severe convective weather， such as big hail， hail， and gust with thunderstorm， are decided.According to the height difference between the height of the 0 ℃ level and the storm top and that between the height of the -20 ℃ level and the storm top， the storms captured by CINRAD are chosen one by one，so to identify the area that will be influenced in the next one hour by storms that may bring about big hail， hail or gust weather.
