Abstract: Based on the disaster reports,meteorological observation data and Doppler radar data from 2010 to 2021,the spatial and temporal distribution of hail and radar echo characteristics of hail cloud in Ili River Valley are analyzed.The results show that:（1）The high incidence period of hail is from May to August.The daily variation is almost from 16:00 to 19:00（BJT）,and the peak is at 17:00.（2）It is easy to occur on the sides of the valley.The hail in Zhaosu County accounts for more than half of the total hail in Ili River Valley,and most of them are ordinary and multi storms,while line storms and superstorms mostly occur in Huocheng County.（3） When the reflectivity is greater than 50 dBZ,the echo height is greater than 8 km,and the VIL jumps,the occurrence of hail should be warned. When the echo height develops more than 11 km,the probability of hail is high.（4）Most ordinary single storms are high hanging centroids; Multi-cell storms have a long life history and may repeatedly affect the same area; The line storm is poorly organized,with loose structure,and hook echo often appears in the lower layer; Super storms basically have all typical echo characteristics,but cyclones are not evident in some cases.
