Abstract: Statistic analyses on a large number of hailstorm echoes show that the differences exist in the cloud top height, the echo area,the intense core height and the thickness when strong convection develops and evolves with the reflectivity Ze>30 dBz of their radar echo for different hailcloud processes. The statistics attained the intensity structure of hailstorm echoes and their parameters of echo characteristics.These parameters of echo characteristics can be used to the hail process as criteria for identifying hailstorms among severe thunderstorm evolution,the accuracy is 92% for identifyirig strong hailstorms.
