利用中国台风网（www.typhoon.gov.cn）的“CMA-STI 热带气旋最佳路径数据集”获取1949-2013年间登陆广东省的热带气旋的登陆位置、强度、路径长度等主要的特征参数，利用模糊 C 聚类（FCM）法建立了登陆广东省热带气旋路径分类方法，并对分类得到的6个路径类型热带气旋在空间分布特征、强度和生命史以及活动时间等方面进行了对比分析。结果表明各类热带气旋特征量有明显的差异。从65年的变化趋势看，广东省热带气旋存在着西多东少的频次规律，而强度分布却是东强西弱。

Based on the best-track dataset from the www.typhoon.gov.cn between 1 949 -201 3,a method is established for objective classification of tropical cyclone (TC)tracks striking Guangdong province by Fuzzy c-means (FCM)that takes into account such characteristic parameters as the position,intensity,path length,etc. Six clusters from classification are analyzed for comparison in terms of the TC’s genesis and landfall position,inten-sity and lifespan,the temporal characteristics was analyzed.These parameters are quite different among the clus-ters.From the trends in the 65 years,the frequency of the western is more than the eastern,while the intensity is opposite.
