| 摘 要： | 介绍了使用多普勒天气雷达对濮阳2005年7月22日暴雨天气过程进行连续监测的情况,利用基本反射率、组合反射率和回波顶、垂直积分液态水、基本速度等雷达产品进行分析。结果表明,此次降水回波持续时间较长,有＂人＂字形回波特征。径向速度产品图上,逆风区与辐合区出现、发展,预示强风暴的出现。速度场的强弱变化早于回波强度变化,可更早得到风暴的发展情况,追踪多普勒径向速度场上的逆风区、辐合区的运动路径,可以大致确定强降水的落区,从而提前预报出灾害性天气。垂直积分液态含水量相对稳定,大值区与强回波区有一定的对应关系。通过分析得出此次暴雨的一些雷达回波特征,可为今后暴雨识别、预报提供参考和依据。

| Abstract: | A rainstorm happened in July 22th 2005 in Puyang which was detected by Doppler Radar was introduced.The radar products such as Vertically Integrated Liquid,Composite Reflectivity,Reflectivity,Velocity,Reflectivity Cross Section and Echo Tops etc were analyzed to find out how to use these products to predict the rainstorm.The results showed that liquid water corresponds to the vertical integration of the resolution of crisis,which continued high liquid water and the vertical integration corresponding to the ... |
