摘　　要：2008年1月10日～2月5日桂林出现了一次持续的低温雨雪冰冻天气,通过对桂林新一代天气雷达资料降雪回波的特征进行了详细分析,总结出桂林市冬季降雪的回波特征,着重提出了"牛眼"的意义及在降雪量分析中的特征和风廓线产品对预报的指示作用,并对新一代天气雷达在降雪监测、降雪预报的应用方面进行了讨论,为南方降雪天气的雷达回波特征做一些总结。A sustained low-temperature freezing rain and snow weather occurred in Guilin from January 10^thto February 5^th of 2008. The echo characteristics of snowfall in Guilin based on a new generation of weather radar data were analyzed in detail. The echo characteristics of winter snowfall in Gullin were sum up. The significance of ＂bovine eye＂ and its characteristics in the snowfall analysis and the role of wind outline product in the prediction were proposed. And the application of a new generation of weather radar in snow monitoring and snow forecasting were discussed. The radar echo characteristics of snowfall in South China were sum up.
