    In order to find the echo characteristics of convective short-time torrential rainfall and typhoon short-time torrential rainfall,the two types of Doppler weather radar data in NingBo during summers in 2004 and 2005 are analyzed based on these echoes' evolution,intensity,products and so on.The results indicate that they have significant differences in characteristics of products,such as Z,TOP and VIL etc.The estimated precipitation from those products,such as OHP and STP were lower than the reals,and the bigger the precipitation,the bigger errors there are;there were also big errors while using the relationship between Z and I to estimate precipitation,especially in the cases of typhoon.Finally,in order to improve the precipitation estimate in summer in Ningbo,the relationships between Z and I under convective and typhoon weather cases are established respectively.
