一次局地突发短时冰雹过程雷达回波分析

Radar Echo Analysis for a Local Short Time Hailstone

本文利用佳木斯雷达站的观测资料,对2010年8月12日清晨桦南县出现的局地突发短时冰雹云的初生、发展、成熟和消亡各阶段的回波演变进行了分析。重点讨论了这次过程中产生冰雹的对流单体回波特征,结合大尺度天气背景及相关雷达产品分析,揭示了此次局地突发短时冰雹天气发生的主要原因,并得出了对突发性冰雹天气的临近预报有参考意义的结论。

we analyzed the radar echo data of Jiamusi Doppler radar station on 12th august 2010 to study a local suddenly happened hail cloudy process from the beginning to disappear.And we focused on both the convective single echo characteristics of this process and the weather situation and the relative radar data,we founded the main forming reason of this short time hailstone weather,and got the conclusion which would be useful for the short-time suddenly happened hailstorm weather prediction.
