Abstract: Based on the best track TC (tropical cyclone) data ( 1949-2006 ) , rapid intensification (RI) process (≥10 m/s in 12 hours) occurring over the coastal waters of China are statistically analysed to determine their geographic and decadal distribution characteristics, as well as the relationship between ENSO and these RITCs occurrence. Different intensity scale of these RITCs are examined to determine their inter-decadal distribution of their occurrence of month. The statistics reveal that ENSO and the distribution of RITC_s origin location have an important impact on the activity of these RITC_s.

Key words: tropical cyclone over the coastal waters of China, rapid intensification, ENSO

摘要： 利用 1949?2006 年西北太平洋热带气旋资料, 对强度迅速加强过程(12小时热带气旋中心附近最大风速增值≥10 m/ s) 发生在我国近海范围内的热带气旋进行了统计分析。总结了近海迅速加强热带气旋地理分布特点、发生时间和强度分布特征, 以及近海迅速加强热带气旋活动与 ENSO 的关系, 并简要分析了ENSO 以及近海热带气旋起源位置对近海迅速加强热带气旋活动的影响机制。
