| 摘 要： | 利用逐时雨量分布图，对登陆珠江三角洲的热带气旋暴雨中尺度特征进行分类、对比和合成分析。实际资料证实了大范围的热带气旋暴雨是由若干中尺度雨团、雨带造成的，纯热带气旋环流形成的中尺度雨团、雨带具有与热带气旋云带大体一致的分布特征；有冷空气与之配合时，热带气旋环流北缘形成东西向的中尺度雨带；热带气旋登陆后的３ｈ可能出现最大中尺度雨团；随热带气旋环流的填塞减弱，中尺度而团也逐渐减弱消失；山地对中尺度雨团的移动起阻滞加强作用，有利的地形与暖湿气流配合，将激发生成新的中尺度雨带。

| Abstract: | The classification,contrast and composite analyses of the meso-scale rainfall characteristics of typhoons which landed in the Zhujiang River Delta are made by 1-hour precipitation charts. The diagnostic analysis of the conventional data around the meso-scale system verify that the storm rainfall of typhoons is composed by several meso-scale rain belts and clusters; These meso-scale belts and clusters which ensued into a pure typhoon circulation manifests similar distribution characteristics as those in a typhoon ; When the relatively cold air invades the typhoon, the meso-scale rain belt will develop at the eastwest in the northern part of the typhoon. And the largest memo-scale rain cluster would appear within three hours after landing. Then, with weakening of the typhoon circulation, the meso-scale rain clusters and belts will also decay and disappear gradually. Hilly area will block the movement of meso-scale rain clusters and make them stronger, so that by coordination of favourable topography and warm humid air, a new meso-scale rain belt will be stimulated. |
