| 摘 要： | 利用1949-2006年登陆中国的热带气旋（TC）资料，分析登陆TC台风季参数的气候特征，结论如下：1) 登陆中国的初旋①以南海生成为主（占5成半），终旋以西太平洋为主（高达8成），近50多年来初、终旋源地分别呈现向东北、西北移动的趋势；2) 广东（浙江）初旋最早（晚），广西、浙江（广东、海南）终旋较早（晚），广东（浙江）台风季最长（短）。近50多年来除浙江台风季呈延长的线性趋势外，其余各省台风季变短或变化不明显。

| Abstract: | According to the data of tropical cyclone (TC) landfalling in China for 1949-2006, climatologically statistical parameters of typhoon season, including the first-landfall TC date (FLTD), the last-landfall TC date (LLTD) and the duration of typhoon season (TSD) were analyzed. The first-landfall (last-landfall) TCs in China are mainly from the South China Sea (the Western Pacific). Moreover, the two source regions show a linear trend of northeastward and northwestward shift, respectively. FLTD in Guangdong (Zhejiang) is the earliest (latest), while LLTD in Guangxi and Zhejiang (Guangdong and Hainan) is earlier (later) than other provinces. TSD in Guangdong (Zhejiang) is longer (shorter) than those in other regions in the recent 58 years. TSD has shortened or shown no obvious change in all provinces except Zhejiang, where it has become longer. |
