| 摘 要： | 本文对2010年8月12日清晨桦南县发生的局地突发短时冰雹天气进行了天气成因分析,表明冷锋前强烈上升气流为冰雹云形成提供了动力条件,锋前新生对流云团发展形成冰雹云。利用雷达基本数据产品揭示了冰雹云形成发展、成熟和消散全过程的主要回波特征,并应用雷达产品对冰雹的识别及与人工识别进行对比,其产品比人工提前10分钟识别冰雹,具有很高的临近冰雹预警应用性能。

| Abstract: | This paper analyzed the hail weather causes occurred on the early morning on August 12th,2010 in Huanan.It showed that the increased airflow before cold front can provided the dynamic conditions for the formation of hail cloud,and before the front a new formative convective cloud can develop into hailstorm.Radar base data products revealed the formation of hail cloud development,maturity and dissipation characteristics of the whole process of the main echo.And the identification and recognition between the ... |
