摘要
对1951-2005年登陆中国的初、终热带气旋①的季节变化、地理分布及年代际变化等作了初步分析。结果表明,初旋发生在4-8月,以6月份频次最多;终旋在8-12月出现,以9月份频次最多。初、终旋在广东、海南和台湾等地登陆最为频繁,尤其以海南岛东南部最为突出。初旋日期表现出明显的年代际变化和偏晚的长期趋势,终旋日期也表现出明显的年代际变化,但无显著的变化趋势。
Study on the geographical distribution, seasonal changes and interdecadal changes of the first-landfall and last-landfall tropical cyclones （TCs） in China were done. Results show that the first-landfall TCs generally occured between April and August, with the maximum frequency in June, while the last-landfall TCs generally appeared between August and December, with the maximum frequency in September. As for geographical distribution, the first-landfall and last-landfall TCs made landfall frequently in coasts of Guangdong, Hainan and Taiwan of China, especially in the southeast coast of Hainan. The date of first-landfall showed obvious interdecadal change and a long-term delaying trend, while the date of last-landfall displayed no long-term trend.
