Abstract: Abstract: 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.
