| 摘 要： | 采用1949～1990年42年的台风资料,对入侵海南岛的台风作了气候统计,得出以下结果:①12年在海南岛登陆的台风有67次,平均每年1.59次;对海南岛有较大影响的台风有48次,平均每年1.14次;两者合计115次,平均每年2.73次。②50至70年代,台风登陆和影响的次数有以10年为周期的规律性变化,即每个年代前5年为高峰期,后5年为低峰期;80年代周期性不明显,说明这种周期性变化只局限在一定时期内。③8,9,10月三个月台风登陆和影响的次数较多,为台风高发季节;8月中旬至10月下旬为台风高发期。④台风入侵海南岛的基本路径有三条:北路、中路、南路。⑤台风登陆地点分布是不均匀的,万宁县港北港至文昌县清澜港、陵水县水口港至三亚市景母角、文昌县翁田至铺前林场三段海岸线较为密集。

| Abstract: | Some climatic characteristics of typhoon invading Hainan Island are discussed by using 42 years of typhoon data (f rom 1949-1990). There were 67 typhoons landing on Hainan Island in the past 42 years,averagely 1.59 per year. There were another 48 typhoons that didn't make their landfall on Hainan but had obvious influence to the island, averagely 1.14 per year. The sum of the two totalled 115 with an average of 2.73 per year. The time of typhoon's landing and its influence presented a regular pattern over each ten years cycle from 1950's to 1970's. The first 5 years were the active period and the later 5 years inactive period in each cycle. The regularity was not clear in 1980's, however. The months August, September and October were the high typhoon season, especially between mid-August to late October. There were three paths of typhoon's invading Hainan Island, i.e. the northern path, the central path and the southern path. No constancy was recorded in typhoon's landing places. The dence places seemed to be from Gangbei port of Wanning County to Qinglan port of Wenchang County, from Shuihou port of Lingshui county to Jingmu promontory of Sanya City, from Wengtian to Puqian Forestry Farm of Wenchang County. |
