Statistical Characteristics of the Radar Echo for Severe Convective Weather in Akesu

The weather radar an important role in monitoring and early warning for severe convective weather.It can be applied to produce the refined short-term forecasting and nowcasting.The parameter of radar echo from 63 hail cloud echoes during 2005-2006 was analyzed,and the echo characteristics of the severe convective weather in May-Aug were obtained.In Akesu,the intensity of severe convective echoes concentrated in 40～60 dBz by 96.8 percent,their negative temperature area thickness were very thick,the average ratio of the thickness for the plus and minus temperature area was 1:2.0.
