| 摘 要： | 华南暴雨第六次加强观测期间 (IOP-6), 1998年6月9日在福建长乐地区出现了一次局地性的强降水过程.该文应用单多普勒天气雷达资料及其风场反演结果对此次过程进行了初步分析, 从多普勒雷达反演的风场结构看, 这次过程与出现在3~5 km高度上的风切变有关, 在低层雷达回波图像上出现中尺度气旋波的结构, 强降水是气旋波活动的结果.

| Abstract: | During the sixth intensive observation of HUAMEX(IOP 6), a local heavy precipitation happened on June 9,1998 in the Changle area of Fujian Province. The process is analyzed preliminarily by using single Doppler weather radar data and retrieved results of the wind field. From the structure of the wind field retrieved from Doppler radar data, we can see that this precipitation was related to the wind shear on the 3-5 km height and was resulted from the activity of a mesoscale cyclone wave which can be identified on the radar echo images. |
