晋城地区冰雹天气的多普勒雷达回波特征分析

Analysis on Doppler Radar Echo Characteristics of Hail in Jincheng Area

利用长治市新一代天气雷达CINRAD/CC的基本产品和导出产品,详细分析并归纳了晋城市冰雹雷达回波的识别特征。结果表明,冰雹云回波较高的基本反射率因子值、三体散射、垂直积分液态含水量跃增、中气旋、冰雹指数、垂直剖面产品中雹云的强回波核的结构特征可作为冰雹天气临近预报的重要依据。

Using basic products and derived products of new generation weather radar CINRAD/CC of Changzhi City,the radar echo recognition characteristics of hail in Jincheng City were analyzed and summarized in detail. The results showed that the basic reflectivity of hail cloud echo top height,TBSS,sharp increase of vertical integrated liquid water content,mesocyclone,hail index,structure characteristics of hail cloud strong center in vertical profile products could be used as important evidences for nowcasting of hail weather in Jincheng City.
