摘　　要：利用海拉尔天气雷达2007—2020年强对流天气过程的雷达资料,通过雷达回波形态识别、特征值统计等方法分析不同季节的雷达回波强度最大值、垂直累积液态水含量、回波顶高、冰雹指数、中气旋等产品特征,并统计强对流过程中回波形状特征,得出海拉尔天气雷达的临近预报预警指标,旨在有效利用雷达产品提升强对流天气预警能力。Using the radar data of the Hailar weather radar during the period of 2007-2020,the maximum radar echo intensity,vertical accumulated liquid water content,echo top height,hail index,mesocyclone and other product characteristics of different seasons were analyzed through radar echo morphology recognition,feature value statistics,and other methods.The echo shape characteristics during the strong convective process were also analyzed to obtain the proximity prediction and warning indicators of the Hailar weather radar,Intended to effectively utilize radar products to enhance strong convective weather warning capabilities.

关 键 词：强对流 回波强度最大值 回波顶高 垂直累积液态含水量
