摘 要: | 利用3824-C单多普勒天气雷达资料,分析了暴雨过程中的中尺度系统:低空急流、暖平流、暖切变、冷切变、逆风区的雷达回波特征;通过对它们的识别及与降水特征、暴雨落区的比较研究,表明这些中尺度系统在暴雨的临近预报中都有明确的指示意义。

Abstract: | Based on the data by a single Doppler weather radar 3824 C,the characteristics of the echo of measoscale systems, including low jet, warm advection,warm shear,cold shear and contrary wind area during a rainstorm are analyzed.It shows that these mesoscale systems are obvious signals for rainstorm feature. |

Keywords: | Doppler weather radar mesoscale system nowcasting of rainstorm |
