| 摘 要： | 本文通过对环流背景和广州CINRAD-SA多普勒天气雷达资料的详细分析,探讨了发生在广州市的一次短时大暴雨的成因.结果表明：广州市夏季短时大暴雨在低空急流、低层辐合以及高空辐散和抽吸作用的有利环流背景下,多个单体接连穿越同一地区所造成,单体排列方向与单体移动方向一致.弱中气旋特征、逆风区和能量锋对对流的维持和加强起到了十分重要的作用.另外本文还对暴雨预警信号的发布技巧进行了探讨.

| Abstract: | The circulation background and data from the Doppler weather radar(CINRAD-SA) in Guangzhou are analyzed and the causes of very-short torrential rains in Guangzhou are analyzed.Results show that the severe rainstorm occurred in Guangzhou in summer was caused by favorable synoptic conditions with multi-cells passing by the same site,being consistent with its moving direction.Weak mesocyclone,the "inverse-wind region" and the energy front plays an important part in convection development and maintenance.In the paper,the skills for issuing rainstorm warning signal are discussed also. |
