[Method] In allusion to the occurrence of hailstorm in Guilin and considering the observation data of a new generation of Doppler weather radar in Guilin, the weather situation and radar echo characteristics in Guilin was summarized so as to explore the short time forecast method. [Result] There were one or two icy storms every year in Guilin. The occurrence of icy storm was distinctly influenced by terrain. A new generation of Doppler weather radar detection ice storm was very effective. The singular intensity of echo of icy storm in Guilin was above or equal to 50 dBz and the height of echo was above or equal to 10 km. The vertical liquid content was above or equal to 40 kg/m2, accompanied by mild cyclone. When there was strong icy storm, there were three flux characteristics. The forecast of icy storm was mainly short time forecast. [Conclusion] The study offered reference for the forecast of icy storm, artificial storm and disaster prevention and mitigation work.展开更多
