| 摘 要： | 台风暴雨最重要的两个因素是雨强和降雨分布，后者即为暴雨的落区。影响台风暴雨落区的因子主要有3个：1）台风涡旋内部结构；2）台风周围环境大气影响；3）台风下垫面强迫作用。本文对这3类因子的作用和影响作了总结。台风暴雨可分为台风环流内的暴雨和台风环流之外的暴雨两大类。本文把台风环流内的暴雨概括为5个落区，包括眼壁暴雨、螺旋雨带暴雨、小涡暴雨、倒槽暴雨、切变暴雨。把台风环流之外的暴雨分为台前飑线暴雨、远距离暴雨和变性下游效应暴雨。地形可能会改变两类暴雨的强度和落区。本文对每一个落区的暴雨特点和形成机理作了总结，对台风暴雨业务预报有一定的参考价值。

| Abstract: | Typhoon rainfall rate and distribution are the two major components in the operational typhoon rainfall forecast. The distribution of typhoon rainfall is mainly affected by three factors: 1) typhoon inner structure; 2) peripheral atmospheric circulation and systems; and 3) underlying surface topography. The rainfalls inside typhoon circulation are grouped into five categories including eyewall rain, spiral band rain, small vortex rain, inverted trough rain, and shear line rain. Typhoon-associated rainfall outside typhoon circulation are divided into squall line rain (about 600 km in front of typhoon center), typhoon remote precipitation (TRP, about one thousand kilometers away from a typhoon), and downstream-effect rainfall (several thousand kilometers away from an extratropical transition typhoon). This paper reviews research progress on the impact of the three factors that may affect typhoon rainfall, the features and formation mechanism of the above different types of typhoon rainfall, which could be helpful for typhoon rainfall operational forecast. |
