| 摘 要： | 运用多普勒雷达的基本反射率(R)、风暴相对径向速度(SRM)、垂直积分液态含水量(VIL)等产品,分析了2004年6月20日华北南部罕见的冰雹大风天气过程。结果表明:这次冰雹大风天气过程主要是由超级单体回波中的中尺度气旋引起的;该过程持续时间比较长的原因是“指状”回波和超级单体回波的依次发生、发展。

| Abstract: | By using the Doppler radar echo about Base Reflectivity(R),Storm Relative Vel Map(SRM),Vert Integrated Liquid(VIL)etc,a severe hail and wind weather process which occured in the south of North China on June 20,2004 is analyzed.The result shows that the hail and severe wind weather process was mainly caused by mesoscale cyclone in supercell storm echo.The reason that the process lasts so long is the development of "finger" echoes and supercell storm echoes. |
