中文摘要：

大雨的三维的风领域在 2005 年 6 月 12-13 日与位于 Meizhou 和 Shantou 的城市的 dual-Doppler 雷达的卷扫描数据在广东省被检索并且学习。这被显示出中央 -- 规模和中央 -- 在低、中间的层位于对流系统的规模集中线在重降雨起一个重要作用。集中线是雨的开始并且维持的机制。三个维的运动学的结构模型也被给。

英文摘要：

The three-dimensional wind fields of the heavy rain on 12-13 June 2005 in Guangdong province are retrieved and studied with the volume scan data of the dual-Doppler radar located in the cities of Meizhou and Shantou. It is shown that the meso-β-scale and meso-γ-scale convergence lines located in the convective system at the low and middle layer play an important role in the heavy rainfall. The convergence line is the initiating and maintaining mechanism of the rain. A three dimensional kinematic structure model is also given.
