中文摘要: 在给出近海急剧加强热带气旋定义的基础上，对1949～2004年在华南近海急剧加强的46个热带气旋的区域和源地、路径和强度、风雨分布等进行分析，得到一些有意义的统计事实。综合分析还发现:热带气旋近海急剧加强主要发生在东高西低、北高南低和弱背景环流中;不同的环境背景下，西南季风、越赤道气流、东风波、弱冷空气、西风槽是诱发近海急剧加强的主要系统。
中文关键词: 热带气旋，近海加强，统计特征，诱发系统
Abstract:Based on the definition of rapidly intensified offshore tropical cyclone (RIO-TC), statistics of the characteristics is made for the 46 RIO-TC cases close to South China coast from 1949 to 2004, and some valuable facts are found. The general circulation of the cases is studied statistically and found the RIO-TCs occur in three patterns of high-east-low-west, high-north-low-south and weak environmental flow, and the inducing systems are mainly southwest monsoon, cross-equatorial flow, easterly wave, weak cold-air and westerly trough under the different patterns.
