The products of CINRADSA Doppler Radar located at Xinle, Hebei Province are used to analyze 8 hail processes in the midsouth part of Heibei Province. Some characteristic indexes of Doppler radar echoes for hail weather are summed up. Hailfall is likely to occur when the echo intensify is above 50 dBz, echo top is greater than 10 km, and vertically integral liquid water (VIL) is above 35 kg/m2. The diameter of hail is bigger when VIL is larger. During the initial stage of echo development, about 2 to 3 volume scanning, the value of VIL increases rapidly. Generally, it is a feature of hailfall that echo intensity for each of volume scanning increases about 10 to 30 kg/m2.
