| 摘 要： | 对6月26日发生在湘中的一次大风过程进行多普勒天气雷达回波分析发现,中低层切变线、地面干线和较强垂直风切变是发生大风的主要背景形势,回波的快速移动、"V"形槽口是雷达回波的总体特征;大风易发生在风暴相对减弱的时期,在雷达产品上具有较低的雷达反射率因子(Z)值,以及较低的垂直积分液态水含量(VIL)和回波顶高(ET)。

| Abstract: | The analysis on Doppler radar products during a strong wind weather event which takes place in the midland of Hunan Province on June,26 shows that middle and low layer wind shear,the surface dry line and more strong vertical wind shear are the main weather situations,and quick moving echoes and "V" notch are the assemble characteristics.Moreover,the strong wind easily takes place in the course of the relative weak phase of thunderstorm.In addition,there are characteristics of lower reflectivity(Z),Vertical Integrated Liquid water(VIL)r and Echo Top values by comparison. |
