摘　　要：文章利用1980年~2011年中国气象局上海台风研究所整编的CMA-STI热带气旋最佳路径数据集,进行西北太平洋热带气旋快速增强阈值的计算确定,并分析快速增强个例的时空分布特征。主要结果有:(1)在西北太平洋海区,选取-30h Pa/24h作为快速增强热带气旋的阈值最恰当;(2)120°E^140°E、12°N^20°N是快速增强热带气旋出现频率最高的区域;(3)9月是快速增强热带气旋出现频数最高的月份,11月是最易形成热带气旋的月份。The rapid intensification threshold vale of tropical cyclone in the northwest Pacific was determined by calculating using the best route data of CMA-STI tropical cyclone from 1980 to 2011 provided by Shanghai typhoon institute of China meteorological administration, and then the spatial and temporal characteristics of the rapid intensification tropical cyclone was analyzed. The main results show that：（1）In the northwest Pacific Ocean,-30 h Pa/24 h is the most threshold value of the rapid intensification tropical cyclone;（2） The occurrence frequency of the rapid intensification tropical cyclones is highest in the areas of 120 °E^140 °E and 12 °N^20 °N;（3） September is the month with the highest frequency of the rapid intensification tropical cyclones, and tropical cyclones is most easily formed into rapid intensification tropical cyclones in November.
